-# Contributing
-
-### Building
-
-You need either [Docker](https://github.com/docker/docker) and `make` (Method 1), or `go` (Method 2) in order to build traefik. For changes to its dependencies, the `glide` dependency management tool and `glide-vc` plugin are required.
-
-#### Method 1: Using `Docker` and `Makefile`
-
-You need to run the `binary` target. This will create binaries for Linux platform in the `dist` folder.
-
-```bash
-$ make binary
-docker build -t "traefik-dev:no-more-godep-ever" -f build.Dockerfile .
-Sending build context to Docker daemon 295.3 MB
-Step 0 : FROM golang:1.7
- ---> 8c6473912976
-Step 1 : RUN go get github.com/Masterminds/glide
-[...]
-docker run --rm  -v "/var/run/docker.sock:/var/run/docker.sock" -it -e OS_ARCH_ARG -e OS_PLATFORM_ARG -e TESTFLAGS -v "/home/emile/dev/go/src/github.com/containous/traefik/"dist":/go/src/github.com/containous/traefik/"dist"" "traefik-dev:no-more-godep-ever" ./script/make.sh generate binary
----> Making bundle: generate (in .)
-removed 'gen.go'
-
----> Making bundle: binary (in .)
-
-$ ls dist/
-traefik*
-```
-
-#### Method 2: Using `go`
-
-###### Setting up your `go` environment
-
-- You need `go` v1.7+
-- It is recommended you clone Træfik into a directory like `~/go/src/github.com/containous/traefik` (This is the official golang workspace hierarchy, and will allow dependencies to resolve properly)
-- This will allow your `GOPATH` and `PATH` variable to be set to `~/go` via:
-```bash
-$ export GOPATH=~/go
-$ export PATH=$PATH:$GOPATH/bin
-```
-
-This can be verified via `$ go env`
-- You will want to add those 2 export lines to your `.bashrc` or `.bash_profile`
-- You need `go-bindata` to be able to use `go generate` command (needed to build) : `$ go get github.com/jteeuwen/go-bindata/...` (Please note, the ellipses are required)
-
-#### Setting up `glide` and `glide-vc` for dependency management
-
-- Glide is not required for building; however, it is necessary to modify dependencies (i.e., add, update, or remove third-party packages)
-- Glide can be installed either via homebrew: `$ brew install glide` or via the official glide script: `$ curl https://glide.sh/get | sh`
-- The glide plugin `glide-vc` must be installed from source: `go get github.com/sgotti/glide-vc`
-
-If you want to add a dependency, use `$ glide get` to have glide put it into the vendor folder and update the glide manifest/lock files (`glide.yaml` and `glide.lock`, respectively). A following `glide-vc` run should be triggered to trim down the size of the vendor folder. The final result must be committed into VCS.
-
-Dependencies for the integration tests in the `integration` folder are managed in a separate `integration/glide.yaml` file using the same toolset.
-
-Care must be taken to choose the right arguments to `glide` when dealing with either main or integration test dependencies, or otherwise risk ending up with a broken build. For that reason, the helper script `script/glide.sh` encapsulates the gory details and conveniently calls `glide-vc` as well. Call it without parameters for basic usage instructions.
-
-Here's a full example:
-
-```bash
-# install the new main dependency github.com/foo/bar and minimize vendor size
-$ ./script/glide.sh get github.com/foo/bar
-# install another dependency, this time for the integration tests
-$ ( cd integration && ../script/glide.sh get github.com/baz/quuz )
-# generate (Only required to integrate other components such as web dashboard)
-$ go generate
-# Standard go build
-$ go build
-# Using gox to build multiple platform
-$ gox "linux darwin" "386 amd64 arm" \
-    -output="dist/traefik_{{.OS}}-{{.Arch}}" \
-    ./cmd/traefik
-# run other commands like tests
-```
-
-### Tests
-
-##### Method 1: `Docker` and `make`
-
-You can run unit tests using the `test-unit` target and the
-integration test using the `test-integration` target.
-
-```bash
-$ make test-unit
-docker build -t "traefik-dev:your-feature-branch" -f build.Dockerfile .
-# […]
-docker run --rm -it -e OS_ARCH_ARG -e OS_PLATFORM_ARG -e TESTFLAGS -v "/home/vincent/src/github/vdemeester/traefik/dist:/go/src/github.com/containous/traefik/dist" "traefik-dev:your-feature-branch" ./script/make.sh generate test-unit
----> Making bundle: generate (in .)
-removed 'gen.go'
-
----> Making bundle: test-unit (in .)
-+ go test -cover -coverprofile=cover.out .
-ok      github.com/containous/traefik   0.005s  coverage: 4.1% of statements
-
-Test success
-```
-
-For development purposes, you can specify which tests to run by using:
-```bash
-# Run every tests in the MyTest suite
-TESTFLAGS="-check.f MyTestSuite" make test-integration
-
-# Run the test "MyTest" in the MyTest suite
-TESTFLAGS="-check.f MyTestSuite.MyTest" make test-integration
-
-# Run every tests starting with "My", in the MyTest suite
-TESTFLAGS="-check.f MyTestSuite.My" make test-integration
-
-# Run every tests ending with "Test", in the MyTest suite
-TESTFLAGS="-check.f MyTestSuite.*Test" make test-integration
-```
-
-More: https://labix.org/gocheck
-
-##### Method 2: `go`
-
-- Tests can be run from the cloned directory, by `$ go test ./...` which should return `ok` similar to:
-```
-ok      _/home/vincent/src/github/vdemeester/traefik    0.004s
-```
-
-### Documentation
-
-The [documentation site](http://docs.traefik.io/) is built with [mkdocs](http://mkdocs.org/)
-
-First make sure you have python and pip installed
-
-```shell
-$ python --version
-Python 2.7.2
-$ pip --version
-pip 1.5.2
-```
-
-Then install mkdocs with pip
-
-```shell
-$ pip install mkdocs
-```
-
-To test documentation locally run `mkdocs serve` in the root directory, this should start a server locally to preview your changes.
-
-```shell
-$ mkdocs serve
-INFO    -  Building documentation...
-WARNING -  Config value: 'theme'. Warning: The theme 'united' will be removed in an upcoming MkDocs release. See http://www.mkdocs.org/about/release-notes/ for more details

+You need either [Docker](https://github.com/docker/docker) and `make` (Method 1), or `go` (Method 2) in order to build Traefik.
+For changes to its dependencies, the `dep` dependency management tool is required.
+
+### Method 1: Using `Docker` and `Makefile`
+
+You need to run the `binary` target. This will create binaries for Linux platform in the `dist` folder.
+
+```bash
+$ make binary
+docker build -t "traefik-dev:no-more-godep-ever" -f build.Dockerfile .
+Sending build context to Docker daemon 295.3 MB
+Step 0 : FROM golang:1.9-alpine
+ ---> 8c6473912976
+Step 1 : RUN go get github.com/golang/dep/cmd/dep
+[...]
+docker run --rm  -v "/var/run/docker.sock:/var/run/docker.sock" -it -e OS_ARCH_ARG -e OS_PLATFORM_ARG -e TESTFLAGS -v "/home/user/go/src/github.com/containous/traefik/"dist":/go/src/github.com/containous/traefik/"dist"" "traefik-dev:no-more-godep-ever" ./script/make.sh generate binary
+---> Making bundle: generate (in .)
+removed 'gen.go'
+
+---> Making bundle: binary (in .)
+
+$ ls dist/
+traefik*
+```
+
+### Method 2: Using `go`
+
+##### Setting up your `go` environment
+
+- You need `go` v1.9+
+- It is recommended you clone Træfik into a directory like `~/go/src/github.com/containous/traefik` (This is the official golang workspace hierarchy, and will allow dependencies to resolve properly)
+- Set your `GOPATH` and `PATH` variable to be set to `~/go` via:
+
+```bash
+export GOPATH=~/go
+export PATH=$PATH:$GOPATH/bin
+```
+
+> Note: You will want to add those 2 export lines to your `.bashrc` or `.bash_profile`
+
+- Verify your environment is setup properly by running `$ go env`.  Depending on your OS and environment you should see output similar to:
+
+```bash
+GOARCH="amd64"
+GOBIN=""
+GOEXE=""
+GOHOSTARCH="amd64"
+GOHOSTOS="linux"
+GOOS="linux"
+GOPATH="/home/<yourusername>/go"
+GORACE=""
+## more go env's will be listed
+```
+
+##### Build Træfik
+
+Once your environment is set up and the Træfik repository cloned you can build Træfik. You need get `go-bindata` once to be able to use `go generate` command as part of the build.  The steps to build are:
+
+```bash
+cd ~/go/src/github.com/containous/traefik
+
+# Get go-bindata. Please note, the ellipses are required
+go get github.com/containous/go-bindata/...
+
+# Start build
+
+# generate
+# (required to merge non-code components into the final binary, such as the web dashboard and provider's Go templates)
+go generate
+
+# Standard go build
+go build ./cmd/traefik
+# run other commands like tests
+```
+
+You will find the Træfik executable in the `~/go/src/github.com/containous/traefik` folder as `traefik`.
+
+### Updating the templates
+
+If you happen to update the provider templates (in `/templates`), you need to run `go generate` to update the `autogen` package.
+
+### Setting up dependency management
+
+[dep](https://github.com/golang/dep) is not required for building; however, it is necessary to modify dependencies (i.e., add, update, or remove third-party packages)
+
+You need to use [dep](https://github.com/golang/dep) >= O.4.1.
+
+If you want to add a dependency, use `dep ensure -add` to have [dep](https://github.com/golang/dep) put it into the vendor folder and update the dep manifest/lock files (`Gopkg.toml` and `Gopkg.lock`, respectively).
+
+A following `make dep-prune` run should be triggered to trim down the size of the vendor folder.
+The final result must be committed into VCS.
+
+Here's a full example using dep to add a new dependency:
+
+```bash
+# install the new main dependency github.com/foo/bar and minimize vendor size
+$ dep ensure -add github.com/foo/bar
+# generate (Only required to integrate other components such as web dashboard)
+$ go generate
+# Standard go build
+$ go build ./cmd/traefik
+# run other commands like tests
+```
+
+### Tests
+
+#### Method 1: `Docker` and `make`
+
+You can run unit tests using the `test-unit` target and the
+integration test using the `test-integration` target.
+
+```bash
+$ make test-unit
+docker build -t "traefik-dev:your-feature-branch" -f build.Dockerfile .
+# […]
+docker run --rm -it -e OS_ARCH_ARG -e OS_PLATFORM_ARG -e TESTFLAGS -v "/home/user/go/src/github/containous/traefik/dist:/go/src/github.com/containous/traefik/dist" "traefik-dev:your-feature-branch" ./script/make.sh generate test-unit
+---> Making bundle: generate (in .)
+removed 'gen.go'
+
+---> Making bundle: test-unit (in .)
++ go test -cover -coverprofile=cover.out .
+ok      github.com/containous/traefik   0.005s  coverage: 4.1% of statements
+
+Test success
+```
+
+For development purposes, you can specify which tests to run by using:
+
+```bash
+# Run every tests in the MyTest suite
+TESTFLAGS="-check.f MyTestSuite" make test-integration
+
+# Run the test "MyTest" in the MyTest suite
+TESTFLAGS="-check.f MyTestSuite.MyTest" make test-integration
+
+# Run every tests starting with "My", in the MyTest suite
+TESTFLAGS="-check.f MyTestSuite.My" make test-integration
+
+# Run every tests ending with "Test", in the MyTest suite
+TESTFLAGS="-check.f MyTestSuite.*Test" make test-integration
+```
+
+More: https://labix.org/gocheck
+
+#### Method 2: `go`
+
+Unit tests can be run from the cloned directory by `$ go test ./...` which should return `ok` similar to:
+
+```
+ok      _/home/user/go/src/github/containous/traefik    0.004s
+```
+
+Integration tests must be run from the `integration/` directory and require the `-integration` switch to be passed like this: `$ cd integration && go test -integration ./...`.
+
+## Documentation
+
+The [documentation site](http://docs.traefik.io/) is built with [mkdocs](http://mkdocs.org/)
+
+### Method 1: `Docker` and `make`
+
+You can test documentation using the `docs` target.
+
+```bash
+$ make docs
+docker build -t traefik-docs -f docs.Dockerfile .
+# […]
+docker run  --rm -v /home/user/go/github/containous/traefik:/mkdocs -p 8000:8000 traefik-docs mkdocs serve
+# […]
+[I 170828 20:47:48 server:283] Serving on http://0.0.0.0:8000
+[I 170828 20:47:48 handlers:60] Start watching changes
+[I 170828 20:47:48 handlers:62] Start detecting changes
+```
+
+And go to [http://127.0.0.1:8000](http://127.0.0.1:8000).
+
+### Method 2: `mkdocs`
+
+First make sure you have python and pip installed
+
+```shell
+$ python --version
+Python 2.7.2
+$ pip --version
+pip 1.5.2
+```
+
+Then install mkdocs with pip
+
+```shell
+pip install --user -r requirements.txt
+```
+
+To test documentation locally run `mkdocs serve` in the root directory, this should start a server locally to preview your changes.
+
+```shell
+$ mkdocs serve
+INFO    -  Building documentation...
+WARNING -  Config value: 'theme'. Warning: The theme 'united' will be removed in an upcoming MkDocs release. See http://www.mkdocs.org/about/release-notes/ for more details

+## PR review process:
+
+* The status `needs-design-review` is only used in complex/heavy/tricky PRs.
+* From `1` to `2`: 1 design LGTM in comment, by a senior maintainer, if needed.
+* From `2` to `3`: 3 LGTM by any maintainer.
+* If needed, a specific maintainer familiar with a particular domain can be requested for the review.
+
+We use [PRM](https://github.com/ldez/prm) to manage locally pull requests.
+
+
+## Bots
+
+### [Myrmica Lobicornis](https://github.com/containous/lobicornis/)
+
+**Update and Merge Pull Request**
+
+The maintainer giving the final LGTM must add the `status/3-needs-merge` label to trigger the merge bot.
+
+By default, a squash-rebase merge will be carried out.
+If you want to preserve commits you must add `bot/merge-method-rebase` before `status/3-needs-merge`.
+
+The status `status/4-merge-in-progress` is only for the bot.
+
+If the bot is not able to perform the merge, the label `bot/need-human-merge` is added.  
+In this case you must solve conflicts/CI/... and after you only need to remove `bot/need-human-merge`.
+
+A maintainer can add `bot/no-merge` on a PR if he want (temporarily) prevent a merge by the bot.
+
+`bot/light-review` can be used to decrease required LGTM from 3 to 1 when:
+
+- vendor updates from previously reviewed PRs
+- merges branches into master
+- prepare release
+

 - One or several files containing Certificate Authorities in PEM format are added.
 - It is possible to have multiple CA:s in the same file or keep them in separate files.

 Rules may be classified in one of two groups: Modifiers and matchers.

 - `AddPrefix: /products`: Add path prefix to the existing request path prior to forwarding the request to the backend.
 - `ReplacePath: /serverless-path`: Replaces the path and adds the old path to the `X-Replaced-Path` header. Useful for mapping to AWS Lambda or Google Cloud Functions.
+- `ReplacePathRegex: ^/api/v2/(.*) /api/$1`: Replaces the path with a regular expression and adds the old path to the `X-Replaced-Path` header. Separate the regular expression and the replacement by a space.

-- `Host: traefik.io, www.traefik.io`: Match request host. It accepts a sequence of literal hosts.
-- `HostRegexp: traefik.io, {subdomain:[a-z]+}.traefik.io`: Match request host. It accepts a sequence of literal and regular expression hosts.
-- `Method: GET, POST, PUT`: Match request HTTP method. It accepts a sequence of HTTP methods.
-- `Path: /products/, /articles/{category}/{id:[0-9]+}`: Match exact request path. It accepts a sequence of literal and regular expression paths.
-- `PathStrip: /products/`: Match exact path and strip off the path prior to forwarding the request to the backend. It accepts a sequence of literal paths.
-- `PathStripRegex: /articles/{category}/{id:[0-9]+}`: Match exact path and strip off the path prior to forwarding the request to the backend. It accepts a sequence of literal and regular expression paths.

-#### Path Matcher Usage Guidelines
+You can optionally enable `passHostHeader` to forward client `Host` header to the backend.
+You can also optionally enable `passTLSCert` to forward TLS Client certificates to the backend.
+
+##### Path Matcher Usage Guidelines
 
 This section explains when to use the various path matchers.
 
 Use `Path` if your backend listens on the exact path only. For instance, `Path: /products` would match `/products` but not `/products/shoes`.
 
-Use a `*Prefix*` matcher if your backend listens on a particular base path but also serves requests on sub-paths. For instance, `PathPrefix: /products` would match `/products` but also `/products/shoes` and `/products/shirts`. Since the path is forwarded as-is, your backend is expected to listen on `/products`.
+Use a `*Prefix*` matcher if your backend listens on a particular base path but also serves requests on sub-paths.
+For instance, `PathPrefix: /products` would match `/products` but also `/products/shoes` and `/products/shirts`.
+Since the path is forwarded as-is, your backend is expected to listen on `/products`.
 
-Use a `*Strip` matcher if your backend listens on the root path (`/`) but should be routeable on a specific prefix. For instance, `PathPrefixStrip: /products` would match `/products` but also `/products/shoes` and `/products/shirts`. Since the path is stripped prior to forwarding, your backend is expected to listen on `/`.
-If your backend is serving assets (e.g., images or Javascript files), chances are it must return properly constructed relative URLs. Continuing on the example, the backend should return `/products/shoes/image.png` (and not `/images.png` which Traefik would likely not be able to associate with the same backend). The `X-Forwarded-Prefix` header (available since Traefik 1.3) can be queried to build such URLs dynamically.

-Instead of distinguishing your backends by path only, you can add a Host matcher to the mix. That way, namespacing of your backends happens on the basis of hosts in addition to paths.

+#### Combining multiple rules
 
 As seen in the previous example, you can combine multiple rules.
 In TOML file, you can use multiple routes:
 
 ```toml
-[frontends.frontend3]
-backend = "backend2"
-  [frontends.frontend3.routes.test_1]
-  rule = "Host:test3.localhost"
-  [frontends.frontend3.routes.test_2]

+    rule = "Host:test3.localhost"
+    [frontends.frontend3.routes.test_2]
+    rule = "Path:/test"
 ```
 
 Here `frontend3` will forward the traffic to the `backend2` if the rules `Host:test3.localhost` **AND** `Path:/test` are matched.
+
 You can also use the notation using a `;` separator, same result:
 
 ```toml
-[frontends.frontend3]
-backend = "backend2"
-  [frontends.frontend3.routes.test_1]
-  rule = "Host:test3.localhost;Path:/test"

+  backend = "backend2"
+    [frontends.frontend3.routes.test_1]
+    rule = "Host:test3.localhost;Path:/test"
 ```
 
 Finally, you can create a rule to bind multiple domains or Path to a frontend, using the `,` separator:
 
 ```toml
-[frontends.frontend2]
-   [frontends.frontend2.routes.test_1]
-   rule = "Host:test1.localhost,test2.localhost"

+```
+
+Here, `frontend1` will be matched before `frontend2` (`(3 + 10 == 13) > (4 + 5 == 9)`).
+
+#### Custom headers
+
+Custom headers can be configured through the frontends, to add headers to either requests or responses that match the frontend's rules.
+This allows for setting headers such as `X-Script-Name` to be added to the request, or custom headers to be added to the response.
+
+!!! warning
+    If the custom header name is the same as one header name of the request or response, it will be replaced.
+
+In this example, all matches to the path `/cheese` will have the `X-Script-Name` header added to the proxied request, and the `X-Custom-Response-Header` added to the response.
 
 ```toml
 [frontends]
   [frontends.frontend1]

-  passHostHeader = true

-Here, `frontend1` will be matched before `frontend2` (`10 > 5`).
+In this second  example, all matches to the path `/cheese` will have the `X-Script-Name` header added to the proxied request, the `X-Custom-Request-Header` removed to the request and the `X-Custom-Response-Header` removed to the response.
 
-## Backends
+```toml
+[frontends]
+  [frontends.frontend1]
+  backend = "backend1"
+    [frontends.frontend1.headers.customresponseheaders]
+    X-Custom-Response-Header = ""
+    [frontends.frontend1.headers.customrequestheaders]
+    X-Script-Name = "test"
+    X-Custom-Request-Header = ""
+    [frontends.frontend1.routes.test_1]
+    rule = "PathPrefixStrip:/cheese"
+```
+
+#### Security headers
+
+Security related headers (HSTS headers, SSL redirection, Browser XSS filter, etc) can be added and configured per frontend in a similar manner to the custom headers above.
+This functionality allows for some easy security features to quickly be set.
+
+An example of some of the security headers:
+
+```toml
+[frontends]
+  [frontends.frontend1]
+  backend = "backend1"
+    [frontends.frontend1.headers]
+    FrameDeny = true
+    [frontends.frontend1.routes.test_1]
+    rule = "PathPrefixStrip:/cheddar"
+  [frontends.frontend2]
+  backend = "backend2"
+    [frontends.frontend2.headers]
+    SSLRedirect = true
+    [frontends.frontend2.routes.test_1]
+    rule = "PathPrefixStrip:/stilton"
+```
+
+In this example, traffic routed through the first frontend will have the `X-Frame-Options` header set to `DENY`, and the second will only allow HTTPS request through, otherwise will return a 301 HTTPS redirect.
+
+!!! note
+    The detailed documentation for those security headers can be found in [unrolled/secure](https://github.com/unrolled/secure#available-options).

+### Why ?
+
+In order to help us learn more about how Træfik is being used and improve it, we collect anonymous usage statistics from running instances.
+Those data help us prioritize our developments and focus on what's more important (for example, which configuration backend is used and which is not used).

+### What ?
+
+Once a day (the first call begins 10 minutes after the start of Træfik), we collect:
+
+- the Træfik version
+- a hash of the configuration
+- an **anonymous version** of the static configuration:
+    - token, user name, password, URL, IP, domain, email, etc, are removed
+
+!!! note
+    We do not collect the dynamic configuration (frontends & backends).

+
+!!! note
+    Even if `TLS-SNI-01` challenge is [disabled](https://community.letsencrypt.org/t/2018-01-11-update-regarding-acme-tls-sni-and-shared-hosting-infrastructure/50188) for the moment, it stays the _by default_ ACME Challenge in Træfik.
+    If `TLS-SNI-01` challenge is not re-enabled in the future, it we will be removed from Træfik.
+
+!!! note
+    If `TLS-SNI-01` challenge is used, `acme.entryPoint` has to be reachable by Let's Encrypt through the port 443.
+    If `HTTP-01` challenge is used, `acme.httpChallenge.entryPoint` has to be defined and reachable by Let's Encrypt through the port 80.
+    These are Let's Encrypt limitations as described on the [community forum](https://community.letsencrypt.org/t/support-for-ports-other-than-80-and-443/3419/72).
+
+### Let's Encrypt downtime
+
+Let's Encrypt functionality will be limited until Træfik is restarted.
+
+If Let's Encrypt is not reachable, these certificates will be used :
+
+  - ACME certificates already generated before downtime
+  - Expired ACME certificates
+  - Provided certificates
+
+!!! note
+    Default Træfik certificate will be used instead of ACME certificates for new (sub)domains (which need Let's Encrypt challenge).
+
+### `storage`
+
+```toml
+[acme]
+# ...
+storage = "acme.json"
+# ...
+```
+
+The `storage` option sets where are stored your ACME certificates.
+
+There are two kind of `storage` :
+
+- a JSON file,
+- a KV store entry.
+
+!!! danger "DEPRECATED"
+    `storage` replaces `storageFile` which is deprecated.
+
+!!! note
+    During Træfik configuration migration from a configuration file to a KV store (thanks to `storeconfig` subcommand as described [here](/user-guide/kv-config/#store-configuration-in-key-value-store)), if ACME certificates have to be migrated too, use both `storageFile` and `storage`.
+
+    - `storageFile` will contain the path to the `acme.json` file to migrate.
+    - `storage` will contain the key where the certificates will be stored.
+
+#### Store data in a file
+
+ACME certificates can be stored in a JSON file which with the `600` right mode.
+
+There are two ways to store ACME certificates in a file from Docker:
+
+- create a file on your host and mount it as a volume:
+```toml
+storage = "acme.json"
+```
+```bash
+docker run -v "/my/host/acme.json:acme.json" traefik
+```
+- mount the folder containing the file as a volume
+```toml
+storage = "/etc/traefik/acme/acme.json"
+```
+```bash
+docker run -v "/my/host/acme:/etc/traefik/acme" traefik
+```
+
+!!! warning
+    This file cannot be shared per many instances of Træfik at the same time.
+    If you have to use Træfik cluster mode, please use [a KV Store entry](/configuration/acme/#storage-kv-entry).
+
+#### Store data in a KV store entry
+
+ACME certificates can be stored in a KV Store entry.
+
+```toml
+storage = "traefik/acme/account"
+```
+
+**This kind of storage is mandatory in cluster mode.**
+
+Because KV stores (like Consul) have limited entries size, the certificates list is compressed before to be set in a KV store entry.
+
+!!! note
+    It's possible to store up to approximately 100 ACME certificates in Consul.
+
+### `acme.httpChallenge`
+
+Use `HTTP-01` challenge to generate/renew ACME certificates.
+
+The redirection is fully compatible with the HTTP-01 challenge.
+You can use redirection with HTTP-01 challenge without problem.
+
+```toml
+[acme]
+# ...
+entryPoint = "https"
+[acme.httpChallenge]
+  entryPoint = "http"
+```
+
+#### `entryPoint`
+
+Specify the entryPoint to use during the challenges.
+
+```toml
+defaultEntryPoints = ["http", "http"]
+
+[entryPoints]
+  [entryPoints.http]
+  address = ":80"
+  [entryPoints.https]
+  address = ":443"
+    [entryPoints.https.tls]
+# ...
+
+[acme]
+  # ...
+  entryPoint = "https"
+  [acme.httpChallenge]
+    entryPoint = "http"
+```
+
+!!! note
+    `acme.httpChallenge.entryPoint` has to be reachable by Let's Encrypt through the port 80.
+    It's a Let's Encrypt limitation as described on the [community forum](https://community.letsencrypt.org/t/support-for-ports-other-than-80-and-443/3419/72).
+
+### `acme.dnsChallenge`
+
+Use `DNS-01` challenge to generate/renew ACME certificates.
+
+```toml
+[acme]
+# ...
+[acme.dnsChallenge]
+  provider = "digitalocean"
+  delayBeforeCheck = 0
+# ...
+```
+
+#### `provider`
+
+Select the provider that matches the DNS domain that will host the challenge TXT record, and provide environment variables to enable setting it:
+
+| Provider Name                                          | Provider code  | Configuration                                                                                                             |

+
+Enable on demand certificate.
+
+This will request a certificate from Let's Encrypt during the first TLS handshake for a host name that does not yet have a certificate.
+
+!!! warning
+    TLS handshakes will be slow when requesting a host name certificate for the first time, this can lead to DoS attacks.
+
+!!! warning
+    Take note that Let's Encrypt have [rate limiting](https://letsencrypt.org/docs/rate-limits).
+
+### `onHostRule`
+
+```toml

+# ...
+```
+
+Enable certificate generation on frontends `Host` rules (for frontends wired on the `acme.entryPoint`).
+
+This will request a certificate from Let's Encrypt for each frontend with a Host rule.
+
+For example, a rule `Host:test1.traefik.io,test2.traefik.io` will request a certificate with main domain `test1.traefik.io` and SAN `test2.traefik.io`.

+If you want that Træfik uses Consul tags correctly you need to defined them like that:
+```json
+traefik.enable=true
+traefik.tags=api
+traefik.tags=external
+```
+
+If the prefix defined in Træfik configuration is `bla`, tags need to be defined like that:
+```json
+bla.enable=true
+bla.tags=api
+bla.tags=external
+```

+## Labels: overriding default behaviour
+
+!!! note
+    If you use a compose file, labels should be defined in the `deploy` part of your service.
+
+    This behavior is only enabled for docker-compose version 3+ ([Compose file reference](https://docs.docker.com/compose/compose-file/#labels-1)).
+
+```yaml
+version: "3"
+services:
+  whoami:
+    deploy:
+      labels:
+        traefik.docker.network: traefik
+```
+
+### On Containers
+
+Labels can be used on containers to override default behaviour.
+

+!!! note
+    If a label is defined both as a `container label` and a `service label` (for example `traefik.<service-name>.port=PORT` and `traefik.port=PORT` ), the `service label` is used to defined the `<service-name>` property (`port` in the example).
+
+    It's possible to mix `container labels` and `service labels`, in this case `container labels` are used as default value for missing `service labels` but no frontends are going to be created with the `container labels`.
+
+    More details in this [example](/user-guide/docker-and-lets-encrypt/#labels).
+
+!!! warning
+    When running inside a container, Træfik will need network access through:
+
+    `docker network connect <network> <traefik-container>`

+
+## Table Items
+
+Items in the `dynamodb` table must have three attributes:
+
+- `id` (string): The id is the primary key.
+- `name`(string): The name is used as the name of the frontend or backend.
+- `frontend` or `backend` (map): This attribute's structure matches exactly the structure of a Frontend or Backend type in Traefik.  
+    See `types/types.go` for details.  
+    The presence or absence of this attribute determines its type.
+    So an item should never have both a `frontend` and a `backend` attribute.

+If `AccessKeyID`/`SecretAccessKey` is not given credentials will be resolved in the following order:
+
+- From environment variables; `AWS_ACCESS_KEY_ID`, `AWS_SECRET_ACCESS_KEY`, and `AWS_SESSION_TOKEN`.
+- Shared credentials, determined by `AWS_PROFILE` and `AWS_SHARED_CREDENTIALS_FILE`, defaults to `default` and `~/.aws/credentials`.
+- EC2 instance role or ECS task role
+
+## Policy

+
+## Configuration mode
+
+You have three choices:
+
+- [Simple](/configuration/backends/file/#simple)
+- [Rules in a Separate File](/configuration/backends/file/#rules-in-a-separate-file)
+- [Multiple `.toml` Files](/configuration/backends/file/#multiple-toml-files)
+
+To enable the file backend, you must either pass the `--file` option to the Træfik binary or put the `[file]` section (with or without inner settings) in the configuration file.
+
+The configuration file allows managing both backends/frontends and HTTPS certificates (which are not [Let's Encrypt](https://letsencrypt.org) certificates generated through Træfik).
+
+### Simple
+
+Add your configuration at the end of the global configuration file `traefik.toml`:
+
+```toml
+defaultEntryPoints = ["http", "https"]
+
+[entryPoints]
+  [entryPoints.http]
+    # ...
+  [entryPoints.https]
+    # ...
+
+[file]
+
+# rules
+[backends]
+  [backends.backend1]
+    # ...
+  [backends.backend2]
+    # ...
+
+[frontends]
+  [frontends.frontend1]
+  # ...
+  [frontends.frontend2]
+  # ...
+  [frontends.frontend3]
+  # ...
+
+# HTTPS certificate
+[[tls]]
+  # ...
+
+[[tls]]
+  # ...
+```
+
+!!! note
+    adding certificates directly to the entrypoint is still maintained but certificates declared in this way cannot be managed dynamically.
+    It's recommended to use the file provider to declare certificates.
+
+### Rules in a Separate File
+
+Put your rules in a separate file, for example `rules.toml`:
+
+```toml
+# traefik.toml
+defaultEntryPoints = ["http", "https"]
+
+[entryPoints]
+  [entryPoints.http]
+    # ...
+  [entryPoints.https]
+    # ...
+
+[file]
+  filename = "rules.toml"
+```
+
+```toml
+# rules.toml
+[backends]
+  [backends.backend1]
+    # ...
+  [backends.backend2]
+    # ...
+
+[frontends]
+  [frontends.frontend1]
+  # ...
+  [frontends.frontend2]
+  # ...
+  [frontends.frontend3]
+  # ...
+
+# HTTPS certificate
+[[tls]]
+  # ...
+
+[[tls]]
+  # ...
+```
+
+### Multiple `.toml` Files
+
+You could have multiple `.toml` files in a directory (and recursively in its sub-directories):
+
+```toml
+[file]
+  directory = "/path/to/config/"
+```
+
+If you want Træfik to watch file changes automatically, just add:
+
+```toml
+[file]
+  watch = true
+```

+# filename = "kubernetes.tmpl"
+```
+
+### `endpoint`
+
+The Kubernetes server endpoint as URL.
+
+When deployed into Kubernetes, Traefik will read the environment variables `KUBERNETES_SERVICE_HOST` and `KUBERNETES_SERVICE_PORT` to construct the endpoint.
+
+The access token will be looked up in `/var/run/secrets/kubernetes.io/serviceaccount/token` and the SSL CA certificate in `/var/run/secrets/kubernetes.io/serviceaccount/ca.crt`.
+Both are provided mounted automatically when deployed inside Kubernetes.
+
+The endpoint may be specified to override the environment variable values inside a cluster.
+
+When the environment variables are not found, Traefik will try to connect to the Kubernetes API server with an external-cluster client.
+In this case, the endpoint is required.
+Specifically, it may be set to the URL used by `kubectl proxy` to connect to a Kubernetes cluster using the granted autentication and authorization of the associated kubeconfig.
+
+### `labelselector`
+
+By default, Traefik processes all Ingress objects in the configured namespaces.
+A label selector can be defined to filter on specific Ingress objects only.
+
+See [label-selectors](https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/#label-selectors) for details.
+
+## Annotations
+
+### General annotations
+
+The following general annotations are applicable on the Ingress object:
+
+- `traefik.frontend.rule.type: PathPrefixStrip`
+    Override the default frontend rule type. Default: `PathPrefix`.
+- `traefik.frontend.priority: "3"`
+    Override the default frontend rule priority.
+- `traefik.frontend.redirect.entryPoint: https`:
+    Enables Redirect to another entryPoint for that frontend (e.g. HTTPS).
+- `traefik.frontend.redirect.regex: ^http://localhost/(.*)`:
+    Redirect to another URL for that frontend. Must be set with `traefik.frontend.redirect.replacement`.
+- `traefik.frontend.redirect.replacement: http://mydomain/$1`:
+    Redirect to another URL for that frontend. Must be set with `traefik.frontend.redirect.regex`.

+    A comma-separated list of IP ranges permitted for access. all source IPs are permitted if the list is empty or a single range is ill-formatted.
+
+!!! note
+    Please note that `traefik.frontend.redirect.regex` and `traefik.frontend.redirect.replacement` do not have to be set if `traefik.frontend.redirect.entryPoint` is defined for the redirection (they will not be used in this case).

+
+### Authentication
+
+Is possible to add additional authentication annotations to the Ingress object.
+The source of the authentication is a Secret object that contains the credentials.
+
+- `ingress.kubernetes.io/auth-type`: `basic`
+    Contains the authentication type. The only permitted type is `basic`.
+- `ingress.kubernetes.io/auth-secret`: `mysecret`
+    Contains the username and password with access to the paths defined in the Ingress object.
+
+The secret must be created in the same namespace as the Ingress object.
+
+The following limitations hold:
+
+- The realm is not configurable; the only supported (and default) value is `traefik`.
+- The Secret must contain a single file only.

+## Labels: overriding default behaviour
+
+Marathon labels may be used to dynamically change the routing and forwarding behaviour.
+
+They may be specified on one of two levels: Application or service.
+
+### Application Level
+
+The following labels can be defined on Marathon applications. They adjust the behaviour for the entire application.

+
+!!! note
+    If Traefik needs access to the Rancher API, you need to set the `endpoint`, `accesskey` and `secretkey` parameters.
+
+    To enable Traefik to fetch information about the Environment it's deployed in only, you need to create an `Environment API Key`.
+    This can be found within the API Key advanced options.
+
+    Add these labels to traefik docker deployment to autogenerated these values:

+# Service Fabric Backend
+
+Træfik can be configured to use Service Fabric as a backend configuration.
+
+See [this repository for an example deployment package and further documentation.](https://aka.ms/traefikonsf)
+
+## Service Fabric
+
+```toml
+################################################################
+# Service Fabric provider
+################################################################
+
+# Enable Service Fabric configuration backend
+[serviceFabric]
+
+# Service Fabric Management Endpoint
+#
+# Required
+#
+clusterManagementUrl = "https://localhost:19080"
+
+# Service Fabric Management Endpoint API Version
+#
+# Required
+# Default: "3.0"
+#
+apiVersion = "3.0"
+
+# Service Fabric Polling Interval (in seconds)
+#
+# Required
+# Default: 10
+#
+refreshSeconds = 10
+
+# Enable TLS connection.
+#
+# Optional
+#
+# [serviceFabric.tls]
+#   ca = "/etc/ssl/ca.crt"
+#   cert = "/etc/ssl/servicefabric.crt"
+#   key = "/etc/ssl/servicefabric.key"
+#   insecureskipverify = true
+```
+
+## Labels
+
+The provider uses labels to configure how services are exposed through Træfik.
+These can be set using Extensions and the Property Manager API
+
+#### Extensions
+
+Set labels with extensions through the services `ServiceManifest.xml` file.
+Here is an example of an extension setting Træfik labels:
+
+```xml
+<StatelessServiceType ServiceTypeName="WebServiceType">
+  <Extensions>
+      <Extension Name="Traefik">
+        <Labels xmlns="http://schemas.microsoft.com/2015/03/fabact-no-schema">
+          <Label Key="traefik.frontend.rule.example2">PathPrefixStrip: /a/path/to/strip</Label>
+          <Label Key="traefik.expose">true</Label>
+          <Label Key="traefik.frontend.passHostHeader">true</Label>
+        </Labels>
+      </Extension>
+  </Extensions>
+</StatelessServiceType>
+```
+
+#### Property Manager 
+
+Set Labels with the property manager API to overwrite and add labels, while your service is running.
+Here is an example of adding a frontend rule using the property manager API. 
+
+```shell
+curl -X PUT \
+  'http://localhost:19080/Names/GettingStartedApplication2/WebService/$/GetProperty?api-version=6.0&IncludeValues=true' \
+  -d '{
+  "PropertyName": "traefik.frontend.rule.default",
+  "Value": {
+    "Kind": "String",
+    "Data": "PathPrefixStrip: /a/path/to/strip"
+  },
+  "CustomTypeId": "LabelType"
+}'
+```
+
+!!! note
+    This functionality will be released in a future version of the [sfctl](https://docs.microsoft.com/en-us/azure/service-fabric/service-fabric-application-lifecycle-sfctl) tool.
+
+## Available Labels
+
+Labels, set through extensions or the property manager, can be used on services to override default behaviour.

+# Web Backend
+
+!!! danger "DEPRECATED"
+    The web provider is deprecated, please use the [api](/configuration/api.md), the [ping](/configuration/ping.md), the [metrics](/configuration/metrics) and the [rest](/configuration/backends/rest.md) provider.
+
+Træfik can be configured:
+
+- using a RESTful api.
+- to use a monitoring system (like Prometheus, DataDog or StatD, ...).
+- to expose a Web Dashboard.
+
+## Configuration
+
+```toml
+# Enable web backend.
+[web]
+
+# Web administration port.
+#
+# Required
+# Default: ":8080"
+#
+address = ":8080"
+
+# SSL certificate and key used.
+#
+# Optional
+#
+# certFile = "traefik.crt"
+# keyFile = "traefik.key"
+
+# Set REST API to read-only mode.
+#
+# Optional
+# Default: false
+#
+readOnly = true
+
+# Set the root path for webui and API
+#
+# Deprecated
+# Optional
+#
+# path = "/mypath"

+
+### Authentication
+
+!!! note
+    The `/ping` path of the API is excluded from authentication (since 1.4).
+
+#### Basic Authentication
+
+Passwords can be encoded in MD5, SHA1 and BCrypt: you can use `htpasswd` to generate those ones.
+
+Users can be specified directly in the TOML file, or indirectly by referencing an external file;
+ if both are provided, the two are merged, with external file contents having precedence.
+
+```toml
+[web]
+# ...
+
+# To enable basic auth on the webui with 2 user/pass: test:test and test2:test2
+[web.auth.basic]
+users = ["test:$apr1$H6uskkkW$IgXLP6ewTrSuBkTrqE8wj/", "test2:$apr1$d9hr9HBB$4HxwgUir3HP4EsggP/QNo0"]
+usersFile = "/path/to/.htpasswd"
+
+# ...
+```
+
+#### Digest Authentication
+
+You can use `htdigest` to generate those ones.
+
+Users can be specified directly in the TOML file, or indirectly by referencing an external file;
+ if both are provided, the two are merged, with external file contents having precedence
+
+```toml
+[web]
+# ...
+
+# To enable digest auth on the webui with 2 user/realm/pass: test:traefik:test and test2:traefik:test2
+[web.auth.digest]
+users = ["test:traefik:a2688e031edb4be6a3797f3882655c05", "test2:traefik:518845800f9e2bfb1f1f740ec24f074e"]
+usersFile = "/path/to/.htdigest"
+
+# ...
+```
+
+
+## Metrics
+
+You can enable Træfik to export internal metrics to different monitoring systems.
+
+### Prometheus
+
+```toml
+[web]
+# ...
+
+# To enable Traefik to export internal metrics to Prometheus
+[web.metrics.prometheus]
+
+# Buckets for latency metrics
+#
+# Optional
+# Default: [0.1, 0.3, 1.2, 5]
+buckets=[0.1,0.3,1.2,5.0]
+
+# ...
+```
+
+### DataDog
+
+```toml
+[web]
+# ...
+
+# DataDog metrics exporter type
+[web.metrics.datadog]
+
+# DataDog's address.
+#
+# Required
+# Default: "localhost:8125"
+#
+address = "localhost:8125"
+
+# DataDog push interval
+#
+# Optional
+# Default: "10s"
+#
+pushinterval = "10s"
+
+# ...
+```
+
+### StatsD
+
+```toml
+[web]
+# ...
+
+# StatsD metrics exporter type
+[web.metrics.statsd]
+
+# StatD's address.
+#
+# Required
+# Default: "localhost:8125"
+#
+address = "localhost:8125"
+
+# StatD push interval
+#
+# Optional
+# Default: "10s"
+#
+pushinterval = "10s"
+
+# ...
+```
+
+### InfluxDB
+
+```toml
+[web]
+# ...
+
+# InfluxDB metrics exporter type
+[web.metrics.influxdb]
+
+# InfluxDB's address.
+#
+# Required
+# Default: "localhost:8089"

+
+# InfluxDB push interval
+#
+# Optional
+# Default: "10s"
+#
+pushinterval = "10s"
+
+# ...
+```
+
+## Statistics
+
+```toml
+[web]
+# ...
+
+# Enable more detailed statistics.
+[web.statistics]
+
+# Number of recent errors logged.

+
+### Deprecation compatibility
+
+#### Path
+
+As the web provider is deprecated, you can handle the `Path` option like this:
+
+```toml
+defaultEntryPoints = ["http"]
+
+[entryPoints]
+  [entryPoints.http]
+  address = ":80"
+
+  [entryPoints.dashboard]
+  address = ":8080"
+
+  [entryPoints.api]
+  address = ":8081"
+
+# Activate API and Dashboard
+[api]
+entryPoint = "api"
+
+[file]
+  [backends]
+    [backends.backend1]
+      [backends.backend1.servers.server1]
+      url = "http://127.0.0.1:8081"
+
+  [frontends]
+    [frontends.frontend1]
+    entryPoints = ["dashboard"]
+    backend = "backend1"
+      [frontends.frontend1.routes.test_1]
+      rule = "PathPrefixStrip:/yourprefix;PathPrefix:/yourprefix"
+```
+
+#### Address
+
+As the web provider is deprecated, you can handle the `Address` option like this:
+
+```toml
+defaultEntryPoints = ["http"]
+
+[entryPoints]
+  [entryPoints.http]
+  address = ":80"
+
+  [entryPoints.ping]
+  address = ":8082"
+
+  [entryPoints.api]
+  address = ":8083"
+
+[ping]
+entryPoint = "ping"
+
+[api]
+entryPoint = "api"
+```
+
+In the above example, you would access a regular path, administration panel, and health-check as follows:
+
+* Regular path: `http://hostname:80/foo`
+* Admin Panel: `http://hostname:8083/`
+* Ping URL: `http://hostname:8082/ping`
+
+In the above example, it is _very_ important to create a named dedicated entry point, and do **not** include it in `defaultEntryPoints`.
+Otherwise, you are likely to expose _all_ services via that entry point.
+
+#### Authentication
+
+As the web provider is deprecated, you can handle the `auth` option like this:
+
+```toml
+defaultEntryPoints = ["http"]
+
+[entryPoints]
+  [entryPoints.http]
+  address = ":80"
+
+ [entryPoints.api]
+   address=":8080"
+   [entryPoints.api.auth]
+     [entryPoints.api.auth.basic]
+       users = [
+         "test:$apr1$H6uskkkW$IgXLP6ewTrSuBkTrqE8wj/",
+         "test2:$apr1$d9hr9HBB$4HxwgUir3HP4EsggP/QNo0",
+       ]
+
+[api]
+entrypoint="api"
+```

+- `graceTimeOut`: Duration to give active requests a chance to finish before Traefik stops.  
+Can be provided in a format supported by [time.ParseDuration](https://golang.org/pkg/time/#ParseDuration) or as raw values (digits).
+If no units are provided, the value is parsed assuming seconds.  
+**Note:** in this time frame no new requests are accepted.
+
+- `ProvidersThrottleDuration`: Backends throttle duration: minimum duration in seconds between 2 events from providers before applying a new configuration.
+It avoids unnecessary reloads if multiples events are sent in a short amount of time.  
+Can be provided in a format supported by [time.ParseDuration](https://golang.org/pkg/time/#ParseDuration) or as raw values (digits).
+If no units are provided, the value is parsed assuming seconds.
+
+- `MaxIdleConnsPerHost`: Controls the maximum idle (keep-alive) connections to keep per-host.  
+If zero, `DefaultMaxIdleConnsPerHost` from the Go standard library net/http module is used.
+If you encounter 'too many open files' errors, you can either increase this value or change the `ulimit`.
+
+- `InsecureSkipVerify` : If set to true invalid SSL certificates are accepted for backends.  
+**Note:** This disables detection of man-in-the-middle attacks so should only be used on secure backend networks.
+
+- `RootCAs`: Register Certificates in the RootCA. This certificates will be use for backends calls.

+- `defaultEntryPoints`: Entrypoints to be used by frontends that do not specify any entrypoint.  
+Each frontend can specify its own entrypoints.
+
+
+## Constraints
+
+In a micro-service architecture, with a central service discovery, setting constraints limits Træfik scope to a smaller number of routes.
+
+Træfik filters services according to service attributes/tags set in your configuration backends.
+
+Supported filters:
+
+- `tag`
+
+### Simple
+
+```toml
+# Simple matching constraint
+constraints = ["tag==api"]
+
+# Simple mismatching constraint
+constraints = ["tag!=api"]
+
+# Globbing
+constraints = ["tag==us-*"]
+```
+
+### Multiple
+
+```toml
+# Multiple constraints
+#   - "tag==" must match with at least one tag
+#   - "tag!=" must match with none of tags
+constraints = ["tag!=us-*", "tag!=asia-*"]
+```
+
+### Backend-specific
+
+Supported backends:
+
+- Docker
+- Consul K/V
+- BoltDB
+- Zookeeper
+- Etcd
+- Consul Catalog
+- Rancher
+- Marathon
+- Kubernetes (using a provider-specific mechanism based on label selectors)
+
+```toml
+# Backend-specific constraint
+[consulCatalog]
+# ...
+constraints = ["tag==api"]
+
+# Backend-specific constraint
+[marathon]
+# ...
+constraints = ["tag==api", "tag!=v*-beta"]
+```
+
+
+## Logs Definition
+
+### Traefik logs
+
+```toml
+# Traefik logs file
+# If not defined, logs to stdout
+#
+# DEPRECATED - see [traefikLog] lower down
+# In case both traefikLogsFile and traefikLog.filePath are specified, the latter will take precedence.
+# Optional
+#
+traefikLogsFile = "log/traefik.log"
+
+# Log level
+#
+# Optional
+# Default: "ERROR"
+#
+# Accepted values, in order of severity: "DEBUG", "INFO", "WARN", "ERROR", "FATAL", "PANIC"
+# Messages at and above the selected level will be logged.
+#
+logLevel = "ERROR"
+```
+
+## Traefik Logs
+
+By default the Traefik log is written to stdout in text format.
+
+To write the logs into a logfile specify the `filePath`.
+```toml
+[traefikLog]
+  filePath = "/path/to/traefik.log"
+```
+
+To write JSON format logs, specify `json` as the format:
+```toml
+[traefikLog]
+  filePath = "/path/to/traefik.log"
+  format   = "json"
+```
+
+### Access Logs
+
+Access logs are written when `[accessLog]` is defined.
+By default it will write to stdout and produce logs in the textual Common Log Format (CLF), extended with additional fields.
+
+To enable access logs using the default settings just add the `[accessLog]` entry.
+```toml
+[accessLog]
+```
+
+To write the logs into a logfile specify the `filePath`.
+```toml
+[accessLog]
+filePath = "/path/to/access.log"
+```
+
+To write JSON format logs, specify `json` as the format:
+```toml
+[accessLog]
+filePath = "/path/to/access.log"
+format = "json"
+```
+
+Deprecated way (before 1.4):
+```toml
+# Access logs file
+#
+# DEPRECATED - see [accessLog] lower down
+#
+accessLogsFile = "log/access.log"
+```
+
+### Log Rotation
+
+Traefik will close and reopen its log files, assuming they're configured, on receipt of a USR1 signal.
+This allows the logs to be rotated and processed by an external program, such as `logrotate`.
+
+!!! note
+    This does not work on Windows due to the lack of USR signals.
+
+
+## Custom Error pages
+
+Custom error pages can be returned, in lieu of the default, according to frontend-configured ranges of HTTP Status codes.
+
+In the example below, if a 503 status is returned from the frontend "website", the custom error page at http://2.3.4.5/503.html is returned with the actual status code set in the HTTP header.
+
+!!! note
+    The `503.html` page itself is not hosted on Traefik, but some other infrastructure.
+
+```toml
+[frontends]
+  [frontends.website]
+  backend = "website"
+  [frontends.website.errors]
+    [frontends.website.errors.network]
+    status = ["500-599"]
+    backend = "error"
+    query = "/{status}.html"
+  [frontends.website.routes.website]
+  rule = "Host: website.mydomain.com"
+
+[backends]
+  [backends.website]
+    [backends.website.servers.website]
+    url = "https://1.2.3.4"
+  [backends.error]
+    [backends.error.servers.error]
+    url = "http://2.3.4.5"
+```
+
+In the above example, the error page rendered was based on the status code.
+Instead, the query parameter can also be set to some generic error page like so: `query = "/500s.html"`
+
+Now the `500s.html` error page is returned for the configured code range.
+The configured status code ranges are inclusive; that is, in the above example, the `500s.html` page will be returned for status codes `500` through, and including, `599`.
+
+Custom error pages are easiest to implement using the file provider.
+For dynamic providers, the corresponding template file needs to be customized accordingly and referenced in the Traefik configuration.
+
+
+## Rate limiting
+
+Rate limiting can be configured per frontend.  
+Multiple sets of rates can be added to each frontend, but the time periods must be unique.
+
+```toml
+[frontends]
+    [frontends.frontend1]
+      # ...
+      [frontends.frontend1.ratelimit]
+        extractorfunc = "client.ip"
+          [frontends.frontend1.ratelimit.rateset.rateset1]
+            period = "10s"
+            average = 100
+            burst = 200
+          [frontends.frontend1.ratelimit.rateset.rateset2]
+            period = "3s"
+            average = 5
+            burst = 10
+```
+
+In the above example, frontend1 is configured to limit requests by the client's ip address.  
+An average of 5 requests every 3 seconds is allowed and an average of 100 requests every 10 seconds.  
+These can "burst" up to 10 and 200 in each period respectively.
+
+
+## Retry Configuration
+
+```toml
+# Enable retry sending request if network error
+[retry]
+
+# Number of attempts
+#
+# Optional
+# Default: (number servers in backend) -1
+#
+# attempts = 3
+```
+
+
+## Health Check Configuration
+
+```toml
+# Enable custom health check options.
+[healthcheck]
+
+# Set the default health check interval.
+#
+# Optional
+# Default: "30s"
+#
+# interval = "30s"
+```
+
+- `interval` set the default health check interval.  
+Will only be effective if health check paths are defined.  
+Given provider-specific support, the value may be overridden on a per-backend basis.  
+Can be provided in a format supported by [time.ParseDuration](https://golang.org/pkg/time/#ParseDuration) or as raw values (digits).  
+If no units are provided, the value is parsed assuming seconds.
+
+## Life Cycle
+
+Controls the behavior of Traefik during the shutdown phase.
+
+```toml
+[lifeCycle]
+
+# Duration to keep accepting requests prior to initiating the graceful
+# termination period (as defined by the `graceTimeOut` option). This
+# option is meant to give downstream load-balancers sufficient time to
+# take Traefik out of rotation.
+# Can be provided in a format supported by [time.ParseDuration](https://golang.org/pkg/time/#ParseDuration) or as raw values (digits).
+# If no units are provided, the value is parsed assuming seconds.
+# The zero duration disables the request accepting grace period, i.e.,
+# Traefik will immediately proceed to the grace period.
+#
+# Optional
+# Default: 0
+#
+# requestAcceptGraceTimeout = "10s"
+
+# Duration to give active requests a chance to finish before Traefik stops.
+# Can be provided in a format supported by [time.ParseDuration](https://golang.org/pkg/time/#ParseDuration) or as raw values (digits).
+# If no units are provided, the value is parsed assuming seconds.
+# Note: in this time frame no new requests are accepted.
+#
+# Optional
+# Default: "10s"
+#
+# graceTimeOut = "10s"
+```
+
+## Timeouts
+
+### Responding Timeouts
+
+`respondingTimeouts` are timeouts for incoming requests to the Traefik instance.
+
+```toml
+[respondingTimeouts]
+
+# readTimeout is the maximum duration for reading the entire request, including the body.
+#
+# Optional
+# Default: "0s"
+#
+# readTimeout = "5s"
+
+# writeTimeout is the maximum duration before timing out writes of the response.
+#
+# Optional
+# Default: "0s"
+#
+# writeTimeout = "5s"
+
+# idleTimeout is the maximum duration an idle (keep-alive) connection will remain idle before closing itself.
+#
+# Optional
+# Default: "180s"
+#
+# idleTimeout = "360s"
+```
+
+- `readTimeout` is the maximum duration for reading the entire request, including the body.  
+If zero, no timeout exists.  
+Can be provided in a format supported by [time.ParseDuration](https://golang.org/pkg/time/#ParseDuration) or as raw values (digits).
+If no units are provided, the value is parsed assuming seconds.
+
+- `writeTimeout` is the maximum duration before timing out writes of the response.  
+It covers the time from the end of the request header read to the end of the response write.
+If zero, no timeout exists.  
+Can be provided in a format supported by [time.ParseDuration](https://golang.org/pkg/time/#ParseDuration) or as raw values (digits).
+If no units are provided, the value is parsed assuming seconds.
+
+- `idleTimeout` is the maximum duration an idle (keep-alive) connection will remain idle before closing itself.  
+If zero, no timeout exists.  
+Can be provided in a format supported by [time.ParseDuration](https://golang.org/pkg/time/#ParseDuration) or as raw values (digits).
+If no units are provided, the value is parsed assuming seconds.
+
+### Forwarding Timeouts
+
+`forwardingTimeouts` are timeouts for requests forwarded to the backend servers.
+
+```toml

+- `dialTimeout` is the amount of time to wait until a connection to a backend server can be established.  
+If zero, no timeout exists.  
+Can be provided in a format supported by [time.ParseDuration](https://golang.org/pkg/time/#ParseDuration) or as raw values (digits).
+If no units are provided, the value is parsed assuming seconds.

+
+### Idle Timeout (deprecated)
+
+Use [respondingTimeouts](/configuration/commons/#responding-timeouts) instead of `IdleTimeout`.
+In the case both settings are configured, the deprecated option will be overwritten.
+
+`IdleTimeout` is the maximum amount of time an idle (keep-alive) connection will remain idle before closing itself.
+This is set to enforce closing of stale client connections.
+
+Can be provided in a format supported by [time.ParseDuration](https://golang.org/pkg/time/#ParseDuration) or as raw values (digits).
+If no units are provided, the value is parsed assuming seconds.

+
+```shell
+--entryPoints='Name:http Address::80'
+--entryPoints='Name:https Address::443 TLS'
+```
+
+!!! note
+    Whitespace is used as option separator and `,` is used as value separator for the list.  
+    The names of the options are case-insensitive.
+
+In compose file the entrypoint syntax is different:
+
+```yaml
+traefik:
+    image: traefik
+    command:
+        - --defaultentrypoints=powpow
+        - "--entryPoints=Name:powpow Address::42 Compress:true"
+```
+or
+```yaml
+traefik:
+    image: traefik
+    command: --defaultentrypoints=powpow --entryPoints='Name:powpow Address::42 Compress:true'
+```
+
+#### All available options:
+
+```ini

+
+## Basic
+
+```toml
+# Entrypoints definition
+#
+# Default:
+# [entryPoints]
+#   [entryPoints.http]
+#   address = ":80"
+#
+[entryPoints]
+  [entryPoints.http]
+  address = ":80"
+```
+
+## Redirect HTTP to HTTPS
+
+To redirect an http entrypoint to an https entrypoint (with SNI support).
+
+```toml
+[entryPoints]
+  [entryPoints.http]
+  address = ":80"
+    [entryPoints.http.redirect]
+    entryPoint = "https"
+  [entryPoints.https]
+  address = ":443"
+    [entryPoints.https.tls]
+      [[entryPoints.https.tls.certificates]]
+      certFile = "integration/fixtures/https/snitest.com.cert"
+      keyFile = "integration/fixtures/https/snitest.com.key"
+      [[entryPoints.https.tls.certificates]]
+      certFile = "integration/fixtures/https/snitest.org.cert"
+      keyFile = "integration/fixtures/https/snitest.org.key"
+```
+
+!!! note
+    Please note that `regex` and `replacement` do not have to be set in the `redirect` structure if an entrypoint is defined for the redirection (they will not be used in this case).
+
+## Rewriting URL
+
+To redirect an entrypoint rewriting the URL.
+
+```toml
+[entryPoints]
+  [entryPoints.http]
+  address = ":80"
+    [entryPoints.http.redirect]
+    regex = "^http://localhost/(.*)"
+    replacement = "http://mydomain/$1"
+```
+
+!!! note
+    Please note that `regex` and `replacement` do not have to be set in the `redirect` structure if an `entrypoint` is defined for the redirection (they will not be used in this case).
+
+Care should be taken when defining replacement expand variables: `$1x` is equivalent to `${1x}`, not `${1}x` (see [Regexp.Expand](https://golang.org/pkg/regexp/#Regexp.Expand)), so use `${1}` syntax.
+
+Regular expressions and replacements can be tested using online tools such as [Go Playground](https://play.golang.org/p/mWU9p-wk2ru) or the [Regex101](https://regex101.com/r/58sIgx/2).
+
+## TLS
+
+### Static Certificates
+
+Define an entrypoint with SNI support.
+
+```toml
+[entryPoints]
+  [entryPoints.https]
+  address = ":443"
+    [entryPoints.https.tls]
+      [[entryPoints.https.tls.certificates]]
+      certFile = "integration/fixtures/https/snitest.com.cert"
+      keyFile = "integration/fixtures/https/snitest.com.key"
+```
+
+!!! note
+    If an empty TLS configuration is done, default self-signed certificates are generated.
+
+
+### Dynamic Certificates
+
+If you need to add or remove TLS certificates while Traefik is started, Dynamic TLS certificates are supported using the [file provider](/configuration/backends/file).
+
+
+## TLS Mutual Authentication
+
+TLS Mutual Authentication can be `optional` or not.
+If it's `optional`, Træfik will authorize connection with certificates not signed by a specified Certificate Authority (CA).
+Otherwise, Træfik will only accept clients that present a certificate signed by a specified Certificate Authority (CA).
+`ClientCAFiles` can be configured with multiple `CA:s` in the same file or use multiple files containing one or several `CA:s`.
+The `CA:s` has to be in PEM format.
+
+By default, `ClientCAFiles` is not optional, all clients will be required to present a valid cert.
+The requirement will apply to all server certs in the entrypoint.
+
+In the example below both `snitest.com` and `snitest.org` will require client certs
+
+```toml
+[entryPoints]
+  [entryPoints.https]
+  address = ":443"
+  [entryPoints.https.tls]
+    [entryPoints.https.tls.ClientCA]
+    files = ["tests/clientca1.crt", "tests/clientca2.crt"]
+    optional = false
+    [[entryPoints.https.tls.certificates]]
+    certFile = "integration/fixtures/https/snitest.com.cert"
+    keyFile = "integration/fixtures/https/snitest.com.key"
+    [[entryPoints.https.tls.certificates]]
+    certFile = "integration/fixtures/https/snitest.org.cert"
+    keyFile = "integration/fixtures/https/snitest.org.key"
+```
+
+!!! note
+    The deprecated argument `ClientCAFiles` allows adding Client CA files which are mandatory.
+    If this parameter exists, the new ones are not checked.
+
+## Authentication
+
+### Basic Authentication
+
+Passwords can be encoded in MD5, SHA1 and BCrypt: you can use `htpasswd` to generate them.
+
+Users can be specified directly in the TOML file, or indirectly by referencing an external file;
+ if both are provided, the two are merged, with external file contents having precedence.
+
+```toml
+# To enable basic auth on an entrypoint with 2 user/pass: test:test and test2:test2
+[entryPoints]
+  [entryPoints.http]
+  address = ":80"
+  [entryPoints.http.auth.basic]
+  users = ["test:$apr1$H6uskkkW$IgXLP6ewTrSuBkTrqE8wj/", "test2:$apr1$d9hr9HBB$4HxwgUir3HP4EsggP/QNo0"]
+  usersFile = "/path/to/.htpasswd"
+```
+
+### Digest Authentication
+
+You can use `htdigest` to generate them.
+
+Users can be specified directly in the TOML file, or indirectly by referencing an external file;
+ if both are provided, the two are merged, with external file contents having precedence
+
+```toml
+# To enable digest auth on an entrypoint with 2 user/realm/pass: test:traefik:test and test2:traefik:test2
+[entryPoints]
+  [entryPoints.http]
+  address = ":80"
+  [entryPoints.http.auth.digest]
+  users = ["test:traefik:a2688e031edb4be6a3797f3882655c05", "test2:traefik:518845800f9e2bfb1f1f740ec24f074e"]
+  usersFile = "/path/to/.htdigest"
+```
+
+### Forward Authentication
+
+This configuration will first forward the request to `http://authserver.com/auth`.
+
+If the response code is 2XX, access is granted and the original request is performed.
+Otherwise, the response from the authentication server is returned.
+
+```toml
+[entryPoints]
+  [entryPoints.http]
+    # ...
+    # To enable forward auth on an entrypoint
+    [entryPoints.http.auth.forward]
+    address = "https://authserver.com/auth"
+
+    # Trust existing X-Forwarded-* headers.
+    # Useful with another reverse proxy in front of Traefik.
+    #
+    # Optional
+    # Default: false
+    #
+    trustForwardHeader = true
+
+    # Enable forward auth TLS connection.
+    #
+    # Optional
+    #
+    [entryPoints.http.auth.forward.tls]
+    cert = "authserver.crt"
+    key = "authserver.key"
+```
+
+## Specify Minimum TLS Version
+
+To specify an https entry point with a minimum TLS version, and specifying an array of cipher suites (from [crypto/tls](https://godoc.org/crypto/tls#pkg-constants)).
+
+```toml
+[entryPoints]
+  [entryPoints.https]
+  address = ":443"
+    [entryPoints.https.tls]
+    minVersion = "VersionTLS12"
+    cipherSuites = [
+      "TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256",
+      "TLS_RSA_WITH_AES_256_GCM_SHA384"
+    ]
+      [[entryPoints.https.tls.certificates]]
+      certFile = "integration/fixtures/https/snitest.com.cert"
+      keyFile = "integration/fixtures/https/snitest.com.key"
+      [[entryPoints.https.tls.certificates]]
+      certFile = "integration/fixtures/https/snitest.org.cert"
+      keyFile = "integration/fixtures/https/snitest.org.key"
+```
+
+## Compression
+
+To enable compression support using gzip format.
+
+```toml
+[entryPoints]
+  [entryPoints.http]
+  address = ":80"
+  compress = true
+```
+
+Responses are compressed when:
+
+* The response body is larger than `512` bytes
+* And the `Accept-Encoding` request header contains `gzip`
+* And the response is not already compressed, i.e. the `Content-Encoding` response header is not already set.
+
+## Whitelisting
+
+To enable IP whitelisting at the entrypoint level.
+
+```toml
+[entryPoints]
+  [entryPoints.http]
+  address = ":80"
+  whiteListSourceRange = ["127.0.0.1/32", "192.168.1.7"]
+```
+
+## ProxyProtocol
+
+To enable [ProxyProtocol](https://www.haproxy.org/download/1.8/doc/proxy-protocol.txt) support.
+Only IPs in `trustedIPs` will lead to remote client address replacement: you should declare your load-balancer IP or CIDR range here (in testing environment, you can trust everyone using `insecure = true`).
+
+!!! danger
+    When queuing Træfik behind another load-balancer, be sure to carefully configure Proxy Protocol on both sides.
+    Otherwise, it could introduce a security risk in your system by forging requests.
+
+```toml
+[entryPoints]
+  [entryPoints.http]
+    address = ":80"
+
+    # Enable ProxyProtocol
+    [entryPoints.http.proxyProtocol]
+      # List of trusted IPs
+      #
+      # Required
+      # Default: []
+      #
+      trustedIPs = ["127.0.0.1/32", "192.168.1.7"]
+
+      # Insecure mode FOR TESTING ENVIRONNEMENT ONLY
+      #
+      # Optional
+      # Default: false
+      #
+      # insecure = true
+```
+
+## Forwarded Header
+
+Only IPs in `trustedIPs` will be authorized to trust the client forwarded headers (`X-Forwarded-*`).
+
+```toml
+[entryPoints]
+  [entryPoints.http]
+    address = ":80"
+
+    # Enable Forwarded Headers
+    [entryPoints.http.forwardedHeaders]
+      # List of trusted IPs
+      #
+      # Required
+      # Default: []
+      #
+      trustedIPs = ["127.0.0.1/32", "192.168.1.7"]

+# Clustering / High Availability on Docker Swarm with Consul
+
+This guide explains how to use Træfik in high availability mode in a Docker Swarm and with Let's Encrypt.
+
+Why do we need Træfik in cluster mode? Running multiple instances should work out of the box?
+
+If you want to use Let's Encrypt with Træfik, sharing configuration or TLS certificates between many Træfik instances, you need Træfik cluster/HA.
+
+Ok, could we mount a shared volume used by all my instances? Yes, you can, but it will not work.
+When you use Let's Encrypt, you need to store certificates, but not only.
+When Træfik generates a new certificate, it configures a challenge and once Let's Encrypt will verify the ownership of the domain, it will ping back the challenge.
+If the challenge is not knowing by other Træfik instances, the validation will fail.
+
+For more information about challenge: [Automatic Certificate Management Environment (ACME)](https://github.com/ietf-wg-acme/acme/blob/master/draft-ietf-acme-acme.md#tls-with-server-name-indication-tls-sni)
+
+## Prerequisites
+
+You will need a working Docker Swarm cluster.
+
+## Træfik configuration
+
+In this guide, we will not use a TOML configuration file, but only command line flag.
+With that, we can use the base image without mounting configuration file or building custom image.
+
+What Træfik should do:
+
+- Listen to 80 and 443
+- Redirect HTTP traffic to HTTPS
+- Generate SSL certificate when a domain is added
+- Listen to Docker Swarm event
+
+### EntryPoints configuration
+
+TL;DR:
+
+```shell    
+$ traefik \
+    --entrypoints='Name:http Address::80 Redirect.EntryPoint:https' \
+    --entrypoints='Name:https Address::443 TLS' \
+    --defaultentrypoints=http,https
+```
+
+To listen to different ports, we need to create an entry point for each.
+
+The CLI syntax is `--entrypoints='Name:a_name Address:an_ip_or_empty:a_port options'`.
+If you want to redirect traffic from one entry point to another, it's the option `Redirect.EntryPoint:entrypoint_name`.
+
+By default, we don't want to configure all our services to listen on http and https, we add a default entry point configuration: `--defaultentrypoints=http,https`.
+
+### Let's Encrypt configuration
+
+TL;DR:
+
+```shell
+$ traefik \
+    --acme \
+    --acme.storage=/etc/traefik/acme/acme.json \
+    --acme.entryPoint=https \
+    --acme.httpChallenge.entryPoint=http \
+    --acme.email=contact@mydomain.ca
+```
+
+Let's Encrypt needs 4 parameters: an TLS entry point to listen to, a non-TLS entry point to allow HTTP challenges, a storage for certificates, and an email for the registration.
+
+To enable Let's Encrypt support, you need to add `--acme` flag.
+
+Now, Træfik needs to know where to store the certificates, we can choose between a key in a Key-Value store, or a file path: `--acme.storage=my/key` or `--acme.storage=/path/to/acme.json`.
+
+The `acme.httpChallenge.entryPoint` flag enables the `HTTP-01` challenge and specifies the entryPoint to use during the challenges.
+
+For your email and the entry point, it's `--acme.entryPoint` and `--acme.email` flags.
+
+### Docker configuration
+
+TL;DR:
+
+```shell
+$ traefik \
+    --docker \
+    --docker.swarmmode \
+    --docker.domain=mydomain.ca \
+    --docker.watch
+```
+
+To enable docker and swarm-mode support, you need to add `--docker` and `--docker.swarmmode` flags.
+To watch docker events, add `--docker.watch`.
+
+### Full docker-compose file
+
+```yaml
+version: "3"
+services:

+    image: traefik:1.5

+## Migrate configuration to Consul
+
+We created a special Træfik command to help configuring your Key Value store from a Træfik TOML configuration file and/or CLI flags.
+
+## Deploy a Træfik cluster
+
+The best way we found is to have an initializer service.
+This service will push the config to Consul via the `storeconfig` sub-command.
+
+This service will retry until finishing without error because Consul may not be ready when the service tries to push the configuration.
+
+The initializer in a docker-compose file will be:
+
+```yaml
+  traefik_init:
+    image: traefik:1.5
+    command:
+      - "storeconfig"
+      - "--api"
+      [...]
+      - "--consul"
+      - "--consul.endpoint=consul:8500"
+      - "--consul.prefix=traefik"
+    networks:
+      - traefik
+    deploy:
+      restart_policy:
+        condition: on-failure
+    depends_on:
+      - consul
+```
+
+And now, the Træfik part will only have the Consul configuration.
+
+```yaml
+  traefik:
+    image: traefik:1.5
+    depends_on:
+      - traefik_init
+      - consul
+    command:
+      - "--consul"
+      - "--consul.endpoint=consul:8500"
+      - "--consul.prefix=traefik"
+    [...]
+```
+
+!!! note
+    For Træfik <1.5.0 add `acme.storage=traefik/acme/account` because Træfik is not reading it from Consul.
+
+If you have some update to do, update the initializer service and re-deploy it.
+The new configuration will be stored in Consul, and you need to restart the Træfik node: `docker service update --force traefik_traefik`.

 # Clustering / High Availability (beta)

+This guide explains how to use Træfik in high availability mode.
+
 In order to deploy and configure multiple Træfik instances, without copying the same configuration file on each instance, we will use a distributed Key-Value store.
 
 ## Prerequisites
 
 You will need a working KV store cluster.
+_(Currently, we recommend [Consul](https://consul.io) .)_
 
 ## File configuration to KV store migration
 
 We created a special Træfik command to help configuring your Key Value store from a Træfik TOML configuration file.
+
 Please refer to [this section](/user-guide/kv-config/#store-configuration-in-key-value-store) to get more details.
 
 ## Deploy a Træfik cluster
 
 Once your Træfik configuration is uploaded on your KV store, you can start each Træfik instance.
-A Træfik cluster is based on a master/slave model.
-When starting, Træfik will elect a master. If this instance fails, another master will be automatically elected.
- 
+
+A Træfik cluster is based on a manager/worker model.
+
+When starting, Træfik will elect a manager.
+If this instance fails, another manager will be automatically elected.
+
+## Træfik cluster and Let's Encrypt
+
+**In cluster mode, ACME certificates have to be stored in [a KV Store entry](/configuration/acme/#storage-kv-entry).**
+
+Thanks to the Træfik cluster mode algorithm (based on [the Raft Consensus Algorithm](https://raft.github.io/)), only one instance will contact Let's encrypt to solve the challenges.
+
+The others instances will get ACME certificate from the KV Store entry.

+# Docker & Traefik
+
+In this use case, we want to use Træfik as a _layer-7_ load balancer with SSL termination for a set of micro-services used to run a web application.
+
+We also want to automatically _discover any services_ on the Docker host and let Træfik reconfigure itself automatically when containers get created (or shut down) so HTTP traffic can be routed accordingly.
+
+In addition, we want to use Let's Encrypt to automatically generate and renew SSL certificates per hostname.
+
+## Setting Up
+
+In order for this to work, you'll need a server with a public IP address, with Docker installed on it.
+
+In this example, we're using the fictitious domain _my-awesome-app.org_.
+
+In real-life, you'll want to use your own domain and have the DNS configured accordingly so the hostname records you'll want to use point to the aforementioned public IP address.
+
+## Networking
+
+Docker containers can only communicate with each other over TCP when they share at least one network.
+This makes sense from a topological point of view in the context of networking, since Docker under the hood creates IPTable rules so containers can't reach other containers _unless you'd want to_.
+
+In this example, we're going to use a single network called `web` where all containers that are handling HTTP traffic (including Træfik) will reside in.
+
+On the Docker host, run the following command:
+
+```shell
+docker network create web
+```
+
+Now, let's create a directory on the server where we will configure the rest of Træfik:
+
+```shell
+mkdir -p /opt/traefik
+```
+
+Within this directory, we're going to create 3 empty files:
+
+```shell
+touch /opt/traefik/docker-compose.yml
+touch /opt/traefik/acme.json && chmod 600 /opt/traefik/acme.json
+touch /opt/traefik/traefik.toml
+```
+
+The `docker-compose.yml` file will provide us with a simple, consistent and more importantly, a deterministic way to create Træfik.
+
+The contents of the file is as follows:
+
+```yaml
+version: '2'
+
+services:
+  traefik:
+    image: traefik:1.3.5
+    restart: always
+    ports:
+      - 80:80
+      - 443:443
+    networks:
+      - web
+    volumes:
+      - /var/run/docker.sock:/var/run/docker.sock
+      - /opt/traefik/traefik.toml:/traefik.toml
+      - /opt/traefik/acme.json:/acme.json
+    container_name: traefik
+
+networks:
+  web:
+    external: true
+```
+
+As you can see, we're mounting the `traefik.toml` file as well as the (empty) `acme.json` file in the container.  
+Also, we're mounting the `/var/run/docker.sock` Docker socket in the container as well, so Træfik can listen to Docker events and reconfigure its own internal configuration when containers are created (or shut down).  
+Also, we're making sure the container is automatically restarted by the Docker engine in case of problems (or: if the server is rebooted).
+We're publishing the default HTTP ports `80` and `443` on the host, and making sure the container is placed within the `web` network we've created earlier on.  
+Finally, we're giving this container a static name called `traefik`.
+
+Let's take a look at a simple `traefik.toml` configuration as well before we'll create the Træfik container:
+
+```toml
+debug = false
+
+logLevel = "ERROR"
+defaultEntryPoints = ["https","http"]
+
+[entryPoints]
+  [entryPoints.http]
+  address = ":80"
+    [entryPoints.http.redirect]
+    entryPoint = "https"
+  [entryPoints.https]
+  address = ":443"
+  [entryPoints.https.tls]
+
+[retry]
+
+[docker]
+endpoint = "unix:///var/run/docker.sock"
+domain = "my-awesome-app.org"
+watch = true
+exposedbydefault = false
+
+[acme]
+email = "your-email-here@my-awesome-app.org"
+storage = "acme.json"
+entryPoint = "https"
+OnHostRule = true
+[acme.httpChallenge]
+entryPoint = "http"
+```
+
+This is the minimum configuration required to do the following:
+
+- Log `ERROR`-level messages (or more severe) to the console, but silence `DEBUG`-level messages
+- Check for new versions of Træfik periodically
+- Create two entry points, namely an `HTTP` endpoint on port `80`, and an `HTTPS` endpoint on port `443` where all incoming traffic on port `80` will immediately get redirected to `HTTPS`.
+- Enable the Docker configuration backend and listen for container events on the Docker unix socket we've mounted earlier. However, **new containers will not be exposed by Træfik by default, we'll get into this in a bit!**
+- Enable automatic request and configuration of SSL certificates using Let's Encrypt.
+    These certificates will be stored in the `acme.json` file, which you can back-up yourself and store off-premises.
+
+Alright, let's boot the container. From the `/opt/traefik` directory, run `docker-compose up -d` which will create and start the Træfik container.
+
+## Exposing Web Services to the Outside World
+
+Now that we've fully configured and started Træfik, it's time to get our applications running!
+
+Let's take a simple example of a micro-service project consisting of various services, where some will be exposed to the outside world and some will not. 
+
+The `docker-compose.yml` of our project looks like this:
+
+```yaml
+version: "2.1"
+
+services:
+  app:
+    image: my-docker-registry.com/my-awesome-app/app:latest
+    depends_on:
+      db:
+        condition: service_healthy
+      redis:
+        condition: service_healthy
+    restart: always
+    networks:
+      - web
+      - default
+    expose:
+      - "9000"
+    labels:
+      - "traefik.backend=my-awesome-app-app"
+      - "traefik.docker.network=web"
+      - "traefik.frontend.rule=Host:app.my-awesome-app.org"
+      - "traefik.enable=true"
+      - "traefik.port=9000"
+      - "traefik.default.protocol=http"
+      - "traefik.admin.frontend.rule=Host:admin-app.my-awesome-app.org"
+      - "traefik.admin.protocol=https"
+      - "traefik.admin.port=9443"
+
+  db:
+    image: my-docker-registry.com/back-end/5.7
+    restart: always
+
+  redis:
+    image: my-docker-registry.com/back-end/redis:4-alpine
+    restart: always
+
+  events:
+    image: my-docker-registry.com/my-awesome-app/events:latest
+    depends_on:
+      db:
+        condition: service_healthy
+      redis:
+        condition: service_healthy
+    restart: always
+    networks:
+      - web
+      - default
+    expose:
+      - "3000"
+    labels:
+      - "traefik.backend=my-awesome-app-events"
+      - "traefik.docker.network=web"
+      - "traefik.frontend.rule=Host:events.my-awesome-app.org"
+      - "traefik.enable=true"
+      - "traefik.port=3000"
+
+networks:
+  web:
+    external: true
+```
+
+Here, we can see a set of services with two applications that we're actually exposing to the outside world.  
+Notice how there isn't a single container that has any published ports to the host -- everything is routed through Docker networks.  
+Also, only the containers that we want traffic to get routed to are attached to the `web` network we created at the start of this document.
+
+Since the `traefik` container we've created and started earlier is also attached to this network, HTTP requests can now get routed to these containers.
+
+### Labels
+
+As mentioned earlier, we don't want containers exposed automatically by Træfik.
+
+The reason behind this is simple: we want to have control over this process ourselves.
+Thanks to Docker labels, we can tell Træfik how to create its internal routing configuration.
+
+Let's take a look at the labels themselves for the `app` service, which is a HTTP webservice listing on port 9000:
+
+```yaml
+- "traefik.backend=my-awesome-app-app"
+- "traefik.docker.network=web"
+- "traefik.frontend.rule=Host:app.my-awesome-app.org"
+- "traefik.enable=true"
+- "traefik.port=9000"
+- "traefik.default.protocol=http"
+- "traefik.admin.frontend.rule=Host:admin-app.my-awesome-app.org"
+- "traefik.admin.protocol=https"
+- "traefik.admin.port=9443"
+```
+
+We use both `container labels` and `service labels`.
+
+#### Container labels
+
+First, we specify the `backend` name which corresponds to the actual service we're routing **to**.
+
+We also tell Træfik to use the `web` network to route HTTP traffic to this container. 
+With the `traefik.enable` label, we tell Træfik to include this container in its internal configuration.
+
+With the `frontend.rule` label, we tell Træfik that we want to route to this container if the incoming HTTP request contains the `Host` `app.my-awesome-app.org`.
+Essentially, this is the actual rule used for Layer-7 load balancing. 
+
+Finally but not unimportantly, we tell Træfik to route **to** port `9000`, since that is the actual TCP/IP port the container actually listens on.
+
+### Service labels
+
+`Service labels` allow managing many routes for the same container.
+
+When both `container labels` and `service labels` are defined, `container labels` are just used as default values for missing `service labels` but no frontend/backend are going to be defined only with these labels.
+Obviously, labels `traefik.frontend.rule` and `traefik.port` described above, will only be used to complete information set in `service labels` during the container frontends/bakends creation.
+
+In the example, two service names are defined : `default` and `admin`.
+They allow creating two frontends and two backends.
+
+- `default` has only one `service label` : `traefik.default.protocol`.
+Træfik will use values set in `traefik.frontend.rule` and `traefik.port` to create the `default` frontend and backend.
+The frontend listens to incoming HTTP requests which contain the `Host` `app.my-awesome-app.org` and redirect them in `HTTP` to the port `9000` of the backend.
+- `admin` has all the `services labels` needed to create the `admin` frontend and backend (`traefik.admin.frontend.rule`, `traefik.admin.protocol`, `traefik.admin.port`).
+Træfik will create a frontend to listen to incoming HTTP requests which contain the `Host` `admin-app.my-awesome-app.org` and redirect them in `HTTPS` to the port `9443` of the backend.
+
+#### Gotchas and tips
+
+- Always specify the correct port where the container expects HTTP traffic using `traefik.port` label.  
+    If a container exposes multiple ports, Træfik may forward traffic to the wrong port.
+    Even if a container only exposes one port, you should always write configuration defensively and explicitly.
+- Should you choose to enable the `exposedbydefault` flag in the `traefik.toml` configuration, be aware that all containers that are placed in the same network as Træfik will automatically be reachable from the outside world, for everyone and everyone to see.
+    Usually, this is a bad idea.
+- With the `traefik.frontend.auth.basic` label, it's possible for Træfik to provide a HTTP basic-auth challenge for the endpoints you provide the label for.
+- Træfik has built-in support to automatically export [Prometheus](https://prometheus.io) metrics
+- Træfik supports websockets out of the box. In the example above, the `events`-service could be a NodeJS-based application which allows clients to connect using websocket protocol.
+    Thanks to the fact that HTTPS in our example is enforced, these websockets are automatically secure as well (WSS)
+
+### Final thoughts
+
+Using Træfik as a Layer-7 load balancer in combination with both Docker and Let's Encrypt provides you with an extremely flexible, powerful and self-configuring solution for your projects.
+
+With Let's Encrypt, your endpoints are automatically secured with production-ready SSL certificates that are renewed automatically as well.

+[[acme.domains]]
+  main = "local3.com"
+[[acme.domains]]
+  main = "local4.com"
+```
+
+This configuration allows generating Let's Encrypt certificates (thanks to `HTTP-01` challenge) for the four domains `local[1-4].com`.
+
+Træfik generates these certificates when it starts.
+
+If a backend is added with a `onHost` rule, Træfik will automatically generate the Let's Encrypt certificate for the new domain (for frontends wired on the `acme.entryPoint`).
+
+### OnDemand option (with HTTP challenge)
+
+```toml
+[entryPoints]
+  [entryPoints.http]
+  address = ":80"
+  [entryPoints.https]
+  address = ":443"
+    [entryPoints.https.tls]

+[acme]
+email = "test@traefik.io"
+storage = "acme.json"
+onDemand = true
+caServer = "http://172.18.0.1:4000/directory"
+entryPoint = "https"
+  [acme.httpChallenge]
+  entryPoint = "http"
+```
+
+This configuration allows generating a Let's Encrypt certificate (thanks to `HTTP-01` challenge) during the first HTTPS request on a new domain.
+
+!!! note
+    This option simplifies the configuration but :
+
+    * TLS handshakes will be slow when requesting a host name certificate for the first time, this can leads to DDoS attacks.
+    * Let's Encrypt have rate limiting: https://letsencrypt.org/docs/rate-limits
+
+    That's why, it's better to use the `onHostRule` option if possible.
+
+### DNS challenge
+
+```toml
+[entryPoints]
+  [entryPoints.https]
+  address = ":443"
+    [entryPoints.https.tls]
+

+[[acme.domains]]
+  main = "local3.com"
+[[acme.domains]]
+  main = "local4.com"
+```
+
+DNS challenge needs environment variables to be executed.
+These variables have to be set on the machine/container which host Træfik.
+
+These variables are described [in this section](/configuration/acme/#provider).
+
+### OnHostRule option and provided certificates (with HTTP challenge)
+
+```toml
+[entryPoints]
+  [entryPoints.http]
+  address = ":80"
+  [entryPoints.https]
+  address = ":443"
+    [entryPoints.https.tls]

+onHostRule = true
+caServer = "http://172.18.0.1:4000/directory"
+entryPoint = "https"
+  [acme.httpChallenge]
+  entryPoint = "http"
+```
+
+Træfik will only try to generate a Let's encrypt certificate (thanks to `HTTP-01` challenge) if the domain cannot be checked by the provided certificates.
+
+### Cluster mode
+
+#### Prerequisites
+
+Before you use Let's Encrypt in a Traefik cluster, take a look to [the key-value store explanations](/user-guide/kv-config) and more precisely at [this section](/user-guide/kv-config/#store-configuration-in-key-value-store), which will describe how to migrate from a acme local storage *(acme.json file)* to a key-value store configuration.
+
+#### Configuration
+
+```toml
+[entryPoints]
+  [entryPoints.http]
+  address = ":80"
+  [entryPoints.https]
+  address = ":443"
+    [entryPoints.https.tls]
+
+[acme]
+email = "test@traefik.io"
+storage = "traefik/acme/account"
+caServer = "http://172.18.0.1:4000/directory"
+entryPoint = "https"
+
+[acme.httpChallenge]
+    entryPoint = "http"
+
+[[acme.domains]]
+  main = "local1.com"
+  sans = ["test1.local1.com", "test2.local1.com"]
+[[acme.domains]]
+  main = "local2.com"
+  sans = ["test1.local2.com", "test2x.local2.com"]
+[[acme.domains]]
+  main = "local3.com"
+[[acme.domains]]
+  main = "local4.com"
+
+[consul]
+  endpoint = "127.0.0.1:8500"
+  watch = true
+  prefix = "traefik"
+```
+
+This configuration allows to use the key `traefik/acme/account` to get/set Let's Encrypt certificates content.
+The `consul` provider contains the configuration.
+
+!!! note
+    It's possible to use others key-value store providers as described [here](/user-guide/kv-config/#key-value-store-configuration).

+## Ping Health Check
+
+The `/ping` health-check URL is enabled with the command-line `--ping` or config file option `[ping]`.
+Thus, if you have a regular path for `/foo` and an entrypoint on `:80`, you would access them as follows:
+
+* Regular path: `http://hostname:80/foo`
+* Admin panel: `http://hostname:8080/`
+* Ping URL: `http://hostname:8080/ping`
+
+However, for security reasons, you may want to be able to expose the `/ping` health-check URL to outside health-checkers, e.g. an Internet service or cloud load-balancer, _without_ exposing your administration panel's port.
+In many environments, the security staff may not _allow_ you to expose it.
+
+You have two options:
+
+* Enable `/ping` on a regular entry point
+* Enable `/ping` on a dedicated port
+
+### Enable ping health check on a regular entry point
+
+To proxy `/ping` from a regular entry point to the administration one without exposing the panel, do the following:
+
+```toml
+defaultEntryPoints = ["http"]
+
+[entryPoints]
+  [entryPoints.http]
+  address = ":80"
+
+[ping]
+entryPoint = "http"
+
+```
+
+The above link `ping` on the `http` entry point and then expose it on port `80`
+
+### Enable ping health check on dedicated port
+
+If you do not want to or cannot expose the health-check on a regular entry point - e.g. your security rules do not allow it, or you have a conflicting path - then you can enable health-check on its own entry point.
+Use the following configuration:
+
+```toml
+defaultEntryPoints = ["http"]
+
+[entryPoints]
+  [entryPoints.http]
+  address = ":80"
+  [entryPoints.ping]
+  address = ":8082"
+
+[ping]
+entryPoint = "ping"
+```
+
+The above is similar to the previous example, but instead of enabling `/ping` on the _default_ entry point, we enable it on a _dedicated_ entry point.
+
+In the above example, you would access a regular path and health-check as follows:
+
+* Regular path: `http://hostname:80/foo`
+* Ping URL: `http://hostname:8082/ping`
+
+Note the dedicated port `:8082` for `/ping`.
+
+In the above example, it is _very_ important to create a named dedicated entry point, and do **not** include it in `defaultEntryPoints`.
+Otherwise, you are likely to expose _all_ services via this entry point.

+# gRPC example
+
+This section explains how to use Traefik as reverse proxy for gRPC application with self-signed certificates.
+
+!!! warning
+    As gRPC needs HTTP2, we need HTTPS certificates on both gRPC Server and Træfik.
+
+<p align="center">
+<img src="/img/grpc.svg" alt="gRPC architecture" title="gRPC architecture" />
+</p>
+
+## gRPC Server certificate
+
+In order to secure the gRPC server, we generate a self-signed certificate for backend url:
+
+```bash
+openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout ./backend.key -out ./backend.cert
+```
+
+That will prompt for information, the important answer is:
+
+```
+Common Name (e.g. server FQDN or YOUR name) []: backend.local
+```
+
+## gRPC Client certificate
+
+Generate your self-signed certificate for frontend url:
+
+```bash
+openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout ./frontend.key -out ./frontend.cert
+```
+
+with
+
+```
+Common Name (e.g. server FQDN or YOUR name) []: frontend.local
+```
+
+## Træfik configuration
+
+At last, we configure our Træfik instance to use both self-signed certificates.
+
+```toml
+defaultEntryPoints = ["https"]
+
+# For secure connection on backend.local
+RootCAs = [ "./backend.cert" ]
+
+[entryPoints]
+  [entryPoints.https]
+  address = ":4443"
+    [entryPoints.https.tls]
+     # For secure connection on frontend.local
+     [[entryPoints.https.tls.certificates]]
+     certFile = "./frontend.cert"
+     keyFile  = "./frontend.key"
+
+
+[api]
+
+[file]
+
+[backends]
+  [backends.backend1]
+    [backends.backend1.servers.server1]
+    # Access on backend with HTTPS
+    url = "https://backend.local:8080"
+
+
+[frontends]
+  [frontends.frontend1]
+  backend = "backend1"
+    [frontends.frontend1.routes.test_1]
+    rule = "Host:frontend.local"
+```
+
+!!! warning
+    With some backends, the server URLs use the IP, so you may need to configure `InsecureSkipVerify` instead of the `RootCAS` to activate HTTPS without hostname verification.
+
+## Conclusion
+
+We don't need specific configuration to use gRPC in Træfik, we just need to be careful that all the exchanges (between client and Træfik, and between Træfik and backend) are HTTPS communications because gRPC uses HTTP2.
+
+## A gRPC example in go
+
+We will use the gRPC greeter example in [grpc-go](https://github.com/grpc/grpc-go/tree/master/examples/helloworld)
+
+!!! warning
+    In order to use this gRPC example, we need to modify it to use HTTPS
+
+So we modify the "gRPC server example" to use our own self-signed certificate:
+
+```go
+// ...
+
+// Read cert and key file
+BackendCert, _ := ioutil.ReadFile("./backend.cert")
+BackendKey, _ := ioutil.ReadFile("./backend.key")
+
+// Generate Certificate struct
+cert, err := tls.X509KeyPair(BackendCert, BackendKey)
+if err != nil {
+  log.Fatalf("failed to parse certificate: %v", err)
+}
+
+// Create credentials
+creds := credentials.NewServerTLSFromCert(&cert)
+
+// Use Credentials in gRPC server options
+serverOption := grpc.Creds(creds)
+var s *grpc.Server = grpc.NewServer(serverOption)
+defer s.Stop()
+
+pb.RegisterGreeterServer(s, &server{})
+err := s.Serve(lis)
+
+// ...
+```
+
+Next we will modify gRPC Client to use our Træfik self-signed certificate:
+
+```go
+// ...
+
+// Read cert file
+FrontendCert, _ := ioutil.ReadFile("./frontend.cert")
+
+// Create CertPool
+roots := x509.NewCertPool()
+roots.AppendCertsFromPEM(FrontendCert)
+
+// Create credentials
+credsClient := credentials.NewClientTLSFromCert(roots, "")
+
+// Dial with specific Transport (with credentials)
+conn, err := grpc.Dial("frontend.local:4443", grpc.WithTransportCredentials(credsClient))
+if err != nil {
+    log.Fatalf("did not connect: %v", err)
+}
+
+defer conn.Close()
+client := pb.NewGreeterClient(conn)
+
+name := "World"
+r, err := client.SayHello(context.Background(), &pb.HelloRequest{Name: name})
+
+// ...

-_Note: your cluster may have suitable ClusterRoles already setup, but the following should work everywhere_
+RoleBindings per namespace enable to restrict granted permissions to the very namespaces only that Træfik is watching over, thereby following the least-privileges principle. This is the preferred approach if Træfik is not supposed to watch all namespaces, and the set of namespaces does not change dynamically. Otherwise, a single ClusterRoleBinding must be employed.
+
+!!! note
+    RoleBindings per namespace are available in Træfik 1.5 and later. Please use ClusterRoleBindings for older versions.

+It's possible to protect access to Traefik through basic authentication. (See the [Kubernetes Ingress](/configuration/backends/kubernetes) configuration page for syntactical details and restrictions.)
 
-First lets start by launching the 3 pods for the cheese websites.
+### Creating the Secret
+
+A. Use `htpasswd` to create a file containing the username and the base64-encoded password:
+
+```shell
+htpasswd -c ./auth myusername
+```
+
+You will be prompted for a password which you will have to enter twice.
+`htpasswd` will create a file with the following:
+
+```shell
+cat auth
+```
+
+```shell
+myusername:$apr1$78Jyn/1K$ERHKVRPPlzAX8eBtLuvRZ0
+```
+
+B. Now use `kubectl` to create a secret in the `monitoring` namespace using the file created by `htpasswd`.
+
+```shell
+kubectl create secret generic mysecret --from-file auth --namespace=monitoring
+```
+
+!!! note
+    Secret must be in same namespace as the Ingress object.
+
+C. Attach the following annotations to the Ingress object:
+
+- `ingress.kubernetes.io/auth-type: "basic"`
+- `ingress.kubernetes.io/auth-secret: "mysecret"`
+
+They specify basic authentication and reference the Secret `mysecret` containing the credentials.
+
+Following is a full Ingress example based on Prometheus:
+
+```yaml
+apiVersion: extensions/v1beta1
+kind: Ingress
+metadata:
+ name: prometheus-dashboard
+ namespace: monitoring
+ annotations:
+   kubernetes.io/ingress.class: traefik
+   ingress.kubernetes.io/auth-type: "basic"
+   ingress.kubernetes.io/auth-secret: "mysecret"

+   http:
+     paths:
+     - backend:
+         serviceName: prometheus
+         servicePort: 9090
+```
+
+You can apply the example as following:

-## Disable passing the Host header
+## Specifying Routing Priorities
 
-By default Træfik will pass the incoming Host header on to the upstream resource.
-There are times however where you may not want this to be the case.
-For example if your service is of the ExternalName type.
+Sometimes you need to specify priority for ingress routes, especially when handling wildcard routes.
+This can be done by adding the `traefik.frontend.priority` annotation, i.e.:
 
-### Disable entirely
+```yaml
+apiVersion: extensions/v1beta1
+kind: Ingress
+metadata:
+  name: wildcard-cheeses
+  annotations:

+spec:
+  rules:

+      - path: /
+        backend:
+          serviceName: stilton
+          servicePort: http
+```
+
+Note that priority values must be quoted to avoid numeric interpretation (which are illegal for annotations).
+
+## Forwarding to ExternalNames
+
+When specifying an [ExternalName](https://kubernetes.io/docs/concepts/services-networking/service/#services-without-selectors),
+Træfik will forward requests to the given host accordingly and use HTTPS when the Service port matches 443.
+This still requires setting up a proper port mapping on the Service from the Ingress port to the (external) Service port.
+
+## Disable passing the Host Header
+
+By default Træfik will pass the incoming Host header to the upstream resource.

-## Excluding an ingress from Træfik
+## Partitioning the Ingress object space
 
-You can control which ingress Træfik cares about by using the `kubernetes.io/ingress.class` annotation.
-By default if the annotation is not set at all Træfik will include the ingress.
-If the annotation is set to anything other than traefik or a blank string Træfik will ignore it.
+By default, Træfik processes every Ingress objects it observes. At times, however, it may be desirable to ignore certain objects. The following sub-sections describe common use cases and how they can be handled with Træfik.
 
+### Between Træfik and other Ingress controller implementations
 
-![](http://i.giphy.com/ujUdrdpX7Ok5W.gif)
+Sometimes Træfik runs along other Ingress controller implementations. One such example is when both Træfik and a cloud provider Ingress controller are active.
+
+The `kubernetes.io/ingress.class` annotation can be attached to any Ingress object in order to control whether Træfik should handle it.
+
+If the annotation is missing, contains an empty value, or the value `traefik`, then the Træfik controller will take responsibility and process the associated Ingress object. If the annotation contains any other value (usually the name of a different Ingress controller), Træfik will ignore the object.
+
+### Between multiple Træfik Deployments
+
+Sometimes multiple Træfik Deployments are supposed to run concurrently. For instance, it is conceivable to have one Deployment deal with internal and another one with external traffic.
+
+For such cases, it is advisable to classify Ingress objects through a label and configure the `labelSelector` option per each Træfik Deployment accordingly. To stick with the internal/external example above, all Ingress objects meant for internal traffic could receive a `traffic-type: internal` label while objects designated for external traffic receive a `traffic-type: external` label. The label selectors on the Træfik Deployments would then be `traffic-type=internal` and `traffic-type=external`, respectively.
+
+## Production advice
+
+### Resource limitations
+
+The examples shown deliberately do not specify any [resource limitations](https://kubernetes.io/docs/concepts/configuration/manage-compute-resources-container/) as there is no one size fits all.
+
+In a production environment, however, it is important to set proper bounds, especially with regards to CPU:
+
+- too strict and Traefik will be throttled while serving requests (as Kubernetes imposes hard quotas)
+- too loose and Traefik may waste resources not available for other containers
+
+When in doubt, you should measure your resource needs, and adjust requests and limits accordingly.

-In general, it is possible to define [readiness checks](https://mesosphere.github.io/marathon/docs/readiness-checks.html) (available since Marathon version 1.1) per application and have Marathon take these into account during the startup phase. The idea is that each application provides an HTTP endpoint that Marathon queries periodically during an ongoing deployment in order to mark the associated readiness check result as successful if and only if the endpoint returns a response within the configured HTTP code range. As long as the check keeps failing, Marathon will not proceed with the deployment (within the configured upgrade stategy bounds).

-Unfortunately, Traefik does not respect the result of the readiness check yet. Support is expected to land in a not-too-distant future release of Traefik, however, as being tracked by [issue 1559](https://github.com/containous/traefik/issues/1559).

-A current mitigation strategy is to enable [retries](http://docs.traefik.io/toml/#retry-configuration) and make sure that a sufficient number of healthy application tasks exist so that one retry will likely hit one of those.

+Beginning with version 1.4, Traefik respects readiness check results if the Traefik option is set and checks are configured on the applications accordingly.
 
-### Shutdown

+    Due to the way readiness check results are currently exposed by the Marathon API, ready tasks may be taken into rotation with a small delay.

-It is possible to install a [termination handler](https://mesosphere.github.io/marathon/docs/health-checks.html) (available since Marathon version 1.3) with each application whose responsibility it is to delay the shutdown process long enough until the backend has been taken out of load-balancing rotation with reasonable confidence (i.e., Traefik has received an update from the Marathon event bus, recomputes the available Marathon backends, and applies the new configuration).

 Traefik already ignores Marathon tasks whose state does not match `TASK_RUNNING`; since terminating tasks transition into the `TASK_KILLING` and eventually `TASK_KILLED` state, there is nothing further that needs to be done on Traefik's end.
 
-How long HTTP requests should continue to be accepted in step 2 depends on how long Traefik needs to receive and process the Marathon configuration update. Under regular operational conditions, it should be on the order of seconds, with 10 seconds possibly being a good default value.

-A failing application always happens unexpectedly, and hence, it is very difficult or even impossible to rule out the adversal effects categorically. Failure reasons vary broadly and could stretch from unacceptable slowness, a task crash, or a network split.

 There are two mitigaton efforts:
 
 1. Configure [Marathon health checks](https://mesosphere.github.io/marathon/docs/health-checks.html) on each application.
 1. Configure Traefik health checks (possibly via the `traefik.backend.healthcheck.*` labels) and make sure they probe with proper frequency.
 
-The Marathon health check makes sure that applications once deemed dysfunctional are being rescheduled to different slaves. However, they might take a while to get triggered and the follow-up processes to complete. For that reason, the Treafik health check provides an additional check that responds more rapidly and does not require a configuration reload to happen. Additionally, it protects from cases that the Marathon health check may not be able to cover, such as a network split.

+#### Reusing Marathon health checks
 
 It may seem obvious to reuse the Marathon health checks as a signal to Traefik whether an application should be taken into load-balancing rotation or not.
 
-Apart from the increased latency a failing health check may have, a major problem with this is is that Marathon does not persist the health check results. Consequently, if a master re-election occurs in the Marathon clusters, all health check results will revert to the _unknown_ state, effectively causing all applications inside the cluster to become unavailable and leading to a complete cluster failure. Re-elections do not only happen during regular maintenance work (often requiring rolling upgrades of the Marathon nodes) but also when the Marathon leader fails spontaneously). As such, there is no way to handle this situation deterministically.

 Finally, Marathon health checks are not mandatory (the default is to use the task state as reported by Mesos), so requiring them for Traefik would raise the entry barrier for Marathon users.
 
-Traefik used to use the health check results but moved away from it as [users reported the dramatic consequences](https://github.com/containous/traefik/issues/653).

-### Draining

-Another common approach is to let a proxy drain backends that are supposed to shut down. That is, once a backend is supposed to shut down, Traefik would stop forwarding requests.

-On the plus side, this would not require any modifications to the application in question. However, implementing this fully within Traefik seems like a non-trivial undertaking. Additionally, the approach is less flexible compared to a custom termination handler since only the latter allows for the implementation of custom termination sequences that go beyond simple request draining (e.g., persisting a snapshot state to disk prior to terminating).

 The feature is currently not implemented; a request for draining in general is at [issue 41](https://github.com/containous/traefik/issues/41).
