 # Contributing
 
-## Building
+Here are some guidelines that should help to start contributing to the project.
 
-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.
+- [Submitting pull Requests](https://doc.traefik.io/traefik/contributing/submitting-pull-requests/)
+- [Submitting issues](https://doc.traefik.io/traefik/contributing/submitting-issues/)
+- [Submitting security issues](https://doc.traefik.io/traefik/contributing/submitting-security-issues/)
+- [Advocating for Traefik](https://doc.traefik.io/traefik/contributing/advocating/)
+- [Triage Process](https://github.com/traefik/contributors-guide/blob/master/issue_triage.md)
 
-### 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/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` v1.9+
-- 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/jteeuwen/go-bindata/...
-
-# Start build
-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`.
-
-### 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.
-
-Care must be taken to choose the right arguments to `glide` when dealing with 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 using glide to add a new dependency:
-
-```bash
-# install the new main dependency github.com/foo/bar and minimize vendor size
-$ ./script/glide.sh get 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/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

-## 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.

-
-## 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`.

-Træfik (pronounced like [traffic](https://speak-ipa.bearbin.net/speak.cgi?speak=%CB%88tr%C3%A6f%C9%AAk)) is a modern HTTP reverse proxy and load balancer made to deploy microservices with ease.

+Traefik (pronounced _traffic_) is a modern HTTP reverse proxy and load balancer that makes deploying microservices easy.
+Traefik integrates with your existing infrastructure components ([Docker](https://www.docker.com/), [Swarm mode](https://docs.docker.com/engine/swarm/), [Kubernetes](https://kubernetes.io), [Consul](https://www.consul.io/), [Etcd](https://coreos.com/etcd/), [Rancher v2](https://rancher.com), [Amazon ECS](https://aws.amazon.com/ecs), ...) and configures itself automatically and dynamically.
+Pointing Traefik at your orchestrator should be the _only_ configuration step you need.

 ## Overview
 
-Imagine that you have deployed a bunch of microservices on your infrastructure. You probably used a service registry (like etcd or consul) and/or an orchestrator (swarm, Mesos/Marathon) to manage all these services.
-If you want your users to access some of your microservices from the Internet, you will have to use a reverse proxy and configure it using virtual hosts or prefix paths:
+Imagine that you have deployed a bunch of microservices with the help of an orchestrator (like Swarm or Kubernetes) or a service registry (like etcd or consul).
+Now you want users to access these microservices, and you need a reverse proxy.
 
-- domain `api.domain.com` will point the microservice `api` in your private network
-- path `domain.com/web` will point the microservice `web` in your private network
-- domain `backoffice.domain.com` will point the microservices `backoffice` in your private network, load-balancing between your multiple instances
+Traditional reverse-proxies require that you configure _each_ route that will connect paths and subdomains to _each_ microservice. 
+In an environment where you add, remove, kill, upgrade, or scale your services _many_ times a day, the task of keeping the routes up to date becomes tedious. 
 
-But a microservices architecture is dynamic... Services are added, removed, killed or upgraded often, eventually several times a day.
+**This is when Traefik can help you!**
 
-Traditional reverse-proxies are not natively dynamic. You can't change their configuration and hot-reload easily.
+Traefik listens to your service registry/orchestrator API and instantly generates the routes so your microservices are connected to the outside world -- without further intervention from your part. 
 
-Here enters Træfik.
-
-![Architecture](docs/img/architecture.png)
-
-Træfik can listen to your service registry/orchestrator API, and knows each time a microservice is added, removed, killed or upgraded, and can generate its configuration automatically.
-Routes to your services will be created instantly.
-
-Run it and forget it!
+**Run Traefik and let it do the work for you!** 
+_(But if you'd rather configure some of your routes manually, Traefik supports that too!)_

 ## Quickstart
 
-You can have a quick look at Træfik in this [Katacoda tutorial](https://www.katacoda.com/courses/traefik/deploy-load-balancer) that shows how to load balance requests between multiple Docker containers. If you are looking for a more comprehensive and real use-case example, you can also check [Play-With-Docker](http://training.play-with-docker.com/traefik-load-balancing/) to see how to load balance between multiple nodes.
-
-Here is a talk given by [Emile Vauge](https://github.com/emilevauge) at [GopherCon 2017](https://gophercon.com/).
-You will learn Træfik basics in less than 10 minutes.

-## Release cycle
-
-- Release: We try to release a new version every 2 months
-  - i.e.: 1.3.0, 1.4.0, 1.5.0
-- Release candidate: we do RC (1.**x**.0-rc**y**) before the final release (1.**x**.0)
-  - i.e.: 1.1.0-rc1 -> 1.1.0-rc2 -> 1.1.0-rc3 -> 1.1.0-rc4 -> 1.1.0
-- Bug-fixes: For each version we release bug fixes
-  - i.e.: 1.1.1, 1.1.2, 1.1.3
-  - those versions contain only bug-fixes
-  - no additional features are delivered in those versions
-- Each version is supported until the next one is released
-  - i.e.: 1.1.x will be supported until 1.2.0 is out
-- We use [Semantic Versioning](http://semver.org/)

-# Basics
-
-## Concepts
-
-Let's take our example from the [overview](/#overview) again:
-
-
-> Imagine that you have deployed a bunch of microservices on your infrastructure. You probably used a service registry (like etcd or consul) and/or an orchestrator (swarm, Mesos/Marathon) to manage all these services.
-> If you want your users to access some of your microservices from the Internet, you will have to use a reverse proxy and configure it using virtual hosts or prefix paths:
-
-> - domain `api.domain.com` will point the microservice `api` in your private network
-> - path `domain.com/web` will point the microservice `web` in your private network
-> - domain `backoffice.domain.com` will point the microservices `backoffice` in your private network, load-balancing between your multiple instances
-
-> ![Architecture](img/architecture.png)
-
-Let's zoom on Træfik and have an overview of its internal architecture:
-
-
-![Architecture](img/internal.png)
-
-- Incoming requests end on [entrypoints](#entrypoints), as the name suggests, they are the network entry points into Træfik (listening port, SSL, traffic redirection...).
-- Traffic is then forwarded to a matching [frontend](#frontends). A frontend defines routes from [entrypoints](#entrypoints) to [backends](#backends).
-Routes are created using requests fields (`Host`, `Path`, `Headers`...) and can match or not a request.
-- The [frontend](#frontends) will then send the request to a [backend](#backends). A backend can be composed by one or more [servers](#servers), and by a load-balancing strategy.
-- Finally, the [server](#servers) will forward the request to the corresponding microservice in the private network.
-
-### Entrypoints
-
-Entrypoints are the network entry points into Træfik.
-They can be defined using:
-
-- a port (80, 443...)
-- SSL (Certificates, Keys, authentication with a client certificate signed by a trusted CA...)
-- redirection to another entrypoint (redirect `HTTP` to `HTTPS`)
-
-Here is an example of entrypoints definition:
-
-```toml
-[entryPoints]
-  [entryPoints.http]
-  address = ":80"
-    [entryPoints.http.redirect]
-    entryPoint = "https"
-  [entryPoints.https]
-  address = ":443"
-    [entryPoints.https.tls]
-      [[entryPoints.https.tls.certificates]]
-      certFile = "tests/traefik.crt"
-      keyFile = "tests/traefik.key"
-```
-
-- Two entrypoints are defined `http` and `https`.
-- `http` listens on port `80` and `https` on port `443`.
-- We enable SSL on `https` by giving a certificate and a key.
-- We also redirect all the traffic from entrypoint `http` to `https`.
-
-And here is another example with client certificate authentication:
-
-```toml
-[entryPoints]
-  [entryPoints.https]
-  address = ":443"
-  [entryPoints.https.tls]
-  clientCAFiles = ["tests/clientca1.crt", "tests/clientca2.crt"]
-    [[entryPoints.https.tls.certificates]]
-    certFile = "tests/traefik.crt"
-    keyFile = "tests/traefik.key"
-```
-
-- We enable SSL on `https` by giving a certificate and a key.
-- 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.
-
-### Frontends
-
-A frontend consists of a set of rules that determine how incoming requests are forwarded from an entrypoint to a backend.
-
-Rules may be classified in one of two groups: Modifiers and matchers.
-
-#### Modifiers
-
-Modifier rules only modify the request. They do not have any impact on routing decisions being made.
-
-Following is the list of existing modifier rules:
-
-- `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.
-
-#### Matchers
-
-Matcher rules determine if a particular request should be forwarded to a backend.
-
-Separate multiple rule values by `,` (comma) in order to enable ANY semantics (i.e., forward a request if any rule matches).
-Does not work for `Headers` and `HeadersRegexp`.
-
-Separate multiple rule values by `;` (semicolon) in order to enable ALL semantics (i.e., forward a request if all rules match).
-
-Following is the list of existing matcher rules along with examples:
-
-| Matcher                                                    | Description                                                                                                                                                                                                                                                                             |

-
-In order to use regular expressions with Host and Path matchers, you must declare an arbitrarily named variable followed by the colon-separated regular expression, all enclosed in curly braces. Any pattern supported by [Go's regexp package](https://golang.org/pkg/regexp/) may be used (example: `/posts/{id:[0-9]+}`).
-
-!!! note
-    The variable has no special meaning; however, it is required by the [gorilla/mux](https://github.com/gorilla/mux) dependency which embeds the regular expression and defines the syntax.
-
-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 `*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.
-
-#### Examples
-
-Here is an example of frontends definition:
-
-```toml
-[frontends]
-  [frontends.frontend1]
-  backend = "backend2"
-    [frontends.frontend1.routes.test_1]
-    rule = "Host:test.localhost,test2.localhost"
-  [frontends.frontend2]
-  backend = "backend1"
-  passHostHeader = true
-  passTLSCert = true
-  priority = 10
-  entrypoints = ["https"] # overrides defaultEntryPoints
-    [frontends.frontend2.routes.test_1]
-    rule = "HostRegexp:localhost,{subdomain:[a-z]+}.localhost"
-  [frontends.frontend3]
-  backend = "backend2"
-    [frontends.frontend3.routes.test_1]
-    rule = "Host:test3.localhost;Path:/test"
-```
-
-- Three frontends are defined: `frontend1`, `frontend2` and `frontend3`
-- `frontend1` will forward the traffic to the `backend2` if the rule `Host:test.localhost,test2.localhost` is matched
-- `frontend2` will forward the traffic to the `backend1` if the rule `Host:localhost,{subdomain:[a-z]+}.localhost` is matched (forwarding client `Host` header to the backend)
-- `frontend3` will forward the traffic to the `backend2` if the rules `Host:test3.localhost` **AND** `Path:/test` are matched
-
-#### 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 = "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"
-```
-
-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"
-  [frontends.frontend3]
-  backend = "backend2"
-    [frontends.frontend3.routes.test_1]
-    rule = "Path:/test1,/test2"
-```
-
-#### Rules Order
-
-When combining `Modifier` rules with `Matcher` rules, it is important to remember that `Modifier` rules **ALWAYS** apply after the `Matcher` rules.
-
-The following rules are both `Matchers` and `Modifiers`, so the `Matcher` portion of the rule will apply first, and the `Modifier` will apply later.
-
-- `PathStrip`
-- `PathStripRegex`
-- `PathPrefixStrip`
-- `PathPrefixStripRegex`
-
-`Modifiers` will be applied in a pre-determined order regardless of their order in the `rule` configuration section.
-
-1. `PathStrip`
-2. `PathPrefixStrip`
-3. `PathStripRegex`
-4. `PathPrefixStripRegex`
-5. `AddPrefix`
-6. `ReplacePath`
-
-#### Priorities
-
-By default, routes will be sorted (in descending order) using rules length (to avoid path overlap):
-`PathPrefix:/12345` will be matched before `PathPrefix:/1234` that will be matched before `PathPrefix:/1`.
-
-You can customize priority by frontend:
-
-```toml
-  [frontends]
-    [frontends.frontend1]
-    backend = "backend1"
-    priority = 10
-    passHostHeader = true
-      [frontends.frontend1.routes.test_1]
-      rule = "PathPrefix:/to"
-    [frontends.frontend2]
-    priority = 5
-    backend = "backend2"
-    passHostHeader = true
-      [frontends.frontend2.routes.test_1]
-      rule = "PathPrefix:/toto"
-```
-
-Here, `frontend1` will be matched before `frontend2` (`10 > 5`).
-
-#### 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.
-
-```toml
-[frontends]
-  [frontends.frontend1]
-  backend = "backend1"
-    [frontends.frontend1.headers.customresponseheaders]
-    X-Custom-Response-Header = "True"
-    [frontends.frontend1.headers.customrequestheaders]
-    X-Script-Name = "test"
-    [frontends.frontend1.routes.test_1]
-    rule = "PathPrefixStrip:/cheese"
-```
-
-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.
-
-#### 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).
-
-### Backends
-
-A backend is responsible to load-balance the traffic coming from one or more frontends to a set of http servers.
-
-Various methods of load-balancing are supported:
-
-- `wrr`: Weighted Round Robin
-- `drr`: Dynamic Round Robin: increases weights on servers that perform better than others.
-    It also rolls back to original weights if the servers have changed.
-
-A circuit breaker can also be applied to a backend, preventing high loads on failing servers.
-Initial state is Standby. CB observes the statistics and does not modify the request.
-In case the condition matches, CB enters Tripped state, where it responds with predefined code or redirects to another frontend.
-Once Tripped timer expires, CB enters Recovering state and resets all stats.
-In case the condition does not match and recovery timer expires, CB enters Standby state.
-
-It can be configured using:
-
-- Methods: `LatencyAtQuantileMS`, `NetworkErrorRatio`, `ResponseCodeRatio`
-- Operators:  `AND`, `OR`, `EQ`, `NEQ`, `LT`, `LE`, `GT`, `GE`
-
-For example:
-
-- `NetworkErrorRatio() > 0.5`: watch error ratio over 10 second sliding window for a frontend
-- `LatencyAtQuantileMS(50.0) > 50`:  watch latency at quantile in milliseconds.
-- `ResponseCodeRatio(500, 600, 0, 600) > 0.5`: ratio of response codes in range [500-600) to  [0-600)
-
-To proactively prevent backends from being overwhelmed with high load, a maximum connection limit can
-also be applied to each backend.
-
-Maximum connections can be configured by specifying an integer value for `maxconn.amount` and
-`maxconn.extractorfunc` which is a strategy used to determine how to categorize requests in order to
-evaluate the maximum connections.
-
-For example:
-```toml
-[backends]
-  [backends.backend1]
-    [backends.backend1.maxconn]
-       amount = 10
-       extractorfunc = "request.host"
-```
-
-- `backend1` will return `HTTP code 429 Too Many Requests` if there are already 10 requests in progress for the same Host header.
-- Another possible value for `extractorfunc` is `client.ip` which will categorize requests based on client source ip.
-- Lastly `extractorfunc` can take the value of `request.header.ANY_HEADER` which will categorize requests based on `ANY_HEADER` that you provide.
-
-Sticky sessions are supported with both load balancers.  
-When sticky sessions are enabled, a cookie called `_TRAEFIK_BACKEND` is set on the initial request.
-On subsequent requests, the client will be directed to the backend stored in the cookie if it is still healthy.
-If not, a new backend will be assigned.
-
-For example:
-```toml
-[backends]
-  [backends.backend1]
-    [backends.backend1.loadbalancer]
-      sticky = true
-```
-
-A health check can be configured in order to remove a backend from LB rotation as long as it keeps returning HTTP status codes other than `200 OK` to HTTP GET requests periodically carried out by Traefik.  
-The check is defined by a pathappended to the backend URL and an interval (given in a format understood by [time.ParseDuration](https://golang.org/pkg/time/#ParseDuration)) specifying how often the health check should be executed (the default being 30 seconds).
-Each backend must respond to the health check within 5 seconds.  
-By default, the port of the backend server is used, however, this may be overridden.
-
-A recovering backend returning 200 OK responses again is being returned to the
-LB rotation pool.
-
-For example:
-```toml
-[backends]
-  [backends.backend1]
-    [backends.backend1.healthcheck]
-    path = "/health"
-    interval = "10s"
-```
-
-To use a different port for the healthcheck:
-```toml
-[backends]
-  [backends.backend1]
-    [backends.backend1.healthcheck]
-    path = "/health"
-    interval = "10s"
-    port = 8080
-```
-
-### Servers
-
-Servers are simply defined using a `url`. You can also apply a custom `weight` to each server (this will be used by load-balancing).
-
-!!! note
-    Paths in `url` are ignored. Use `Modifier` to specify paths instead.
-
-Here is an example of backends and servers definition:
-
-```toml
-[backends]
-  [backends.backend1]
-    [backends.backend1.circuitbreaker]
-    expression = "NetworkErrorRatio() > 0.5"
-    [backends.backend1.servers.server1]
-    url = "http://172.17.0.2:80"
-    weight = 10
-    [backends.backend1.servers.server2]
-    url = "http://172.17.0.3:80"
-    weight = 1
-  [backends.backend2]
-    [backends.backend2.LoadBalancer]
-    method = "drr"
-    [backends.backend2.servers.server1]
-    url = "http://172.17.0.4:80"
-    weight = 1
-    [backends.backend2.servers.server2]
-    url = "http://172.17.0.5:80"
-    weight = 2
-```
-
-- Two backends are defined: `backend1` and `backend2`
-- `backend1` will forward the traffic to two servers: `http://172.17.0.2:80"` with weight `10` and `http://172.17.0.3:80` with weight `1` using default `wrr` load-balancing strategy.
-- `backend2` will forward the traffic to two servers: `http://172.17.0.4:80"` with weight `1` and `http://172.17.0.5:80` with weight `2` using `drr` load-balancing strategy.
-- a circuit breaker is added on `backend1` using the expression `NetworkErrorRatio() > 0.5`: watch error ratio over 10 second sliding window
-
-
-## Configuration
-
-Træfik's configuration has two parts:
-
-- The [static Træfik configuration](/basics#static-trfk-configuration) which is loaded only at the beginning.
-- The [dynamic Træfik configuration](/basics#dynamic-trfk-configuration) which can be hot-reloaded (no need to restart the process).
-
-### Static Træfik configuration
-
-The static configuration is the global configuration which is setting up connections to configuration backends and entrypoints.
-
-Træfik can be configured using many configuration sources with the following precedence order.
-Each item takes precedence over the item below it:
-
-- [Key-value store](/basics/#key-value-stores)
-- [Arguments](/basics/#arguments)
-- [Configuration file](/basics/#configuration-file)
-- Default
-
-It means that arguments override configuration file, and key-value store overrides arguments.
-
-!!! note 
-    the provider-enabling argument parameters (e.g., `--docker`) set all default values for the specific provider.  
-    It must not be used if a configuration source with less precedence wants to set a non-default provider value.
-
-#### Configuration file
-
-By default, Træfik will try to find a `traefik.toml` in the following places:
-
-- `/etc/traefik/`
-- `$HOME/.traefik/`
-- `.` _the working directory_
-
-You can override this by setting a `configFile` argument:
-
-```bash
-traefik --configFile=foo/bar/myconfigfile.toml
-```
-
-Please refer to the [global configuration](/configuration/commons) section to get documentation on it.
-
-#### Arguments
-
-Each argument (and command) is described in the help section:
-
-```bash
-traefik --help
-```
-
-Note that all default values will be displayed as well.
-
-#### Key-value stores
-
-Træfik supports several Key-value stores:
-
-- [Consul](https://consul.io)
-- [etcd](https://coreos.com/etcd/)
-- [ZooKeeper](https://zookeeper.apache.org/)
-- [boltdb](https://github.com/boltdb/bolt)
-
-Please refer to the [User Guide Key-value store configuration](/user-guide/kv-config/) section to get documentation on it.
-
-### Dynamic Træfik configuration
-
-The dynamic configuration concerns :
-
-- [Frontends](/basics/#frontends)
-- [Backends](/basics/#backends)
-- [Servers](/basics/#servers)
-
-Træfik can hot-reload those rules which could be provided by [multiple configuration backends](/configuration/commons).
-
-We only need to enable `watch` option to make Træfik watch configuration backend changes and generate its configuration automatically.
-Routes to services will be created and updated instantly at any changes.
-
-Please refer to the [configuration backends](/configuration/commons) section to get documentation on it.
-
-## Commands
-
-### traefik
-
-Usage:
-```bash
-traefik [command] [--flag=flag_argument]
-```
-
-List of Træfik available commands with description :
-
-- `version` : Print version
-- `storeconfig` : Store the static Traefik configuration into a Key-value stores. Please refer to the [Store Træfik configuration](/user-guide/kv-config/#store-trfk-configuration) section to get documentation on it.
-- `bug`: The easiest way to submit a pre-filled issue.
-- `healthcheck`: Calls Traefik `/ping` to check health.
-
-Each command may have related flags.
-
-All those related flags will be displayed with :
-
-```bash
-traefik [command] --help
-```
-
-Each command is described at the beginning of the help section:
-
-```bash
-traefik --help
-```
-
-### Command: bug
-
-Here is the easiest way to submit a pre-filled issue on [Træfik GitHub](https://github.com/containous/traefik).
-
-```bash
-traefik bug
-```
-
-Watch [this demo](https://www.youtube.com/watch?v=Lyz62L8m93I).
-
-### Command: healthcheck
-
-This command allows to check the health of Traefik. Its exit status is `0` if Traefik is healthy and `1` if it is unhealthy.
-
-This can be used with Docker [HEALTHCHECK](https://docs.docker.com/engine/reference/builder/#healthcheck) instruction or any other health check orchestration mechanism.
-
-!!! note
-    The [`web` provider](/configuration/backends/web) must be enabled to allow `/ping` calls by the `healthcheck` command.
-
-```bash
-traefik healthcheck
-```
-```bash
-OK: http://:8082/ping

-
-## Conclusion
-
-Traefik is obviously slower than Nginx, but not so much: Traefik can serve 28392 requests/sec and Nginx 33591 requests/sec which gives a ratio of 85%.
-Not bad for young project :) !
-
-Some areas of possible improvements:
-
-- Use [GO_REUSEPORT](https://github.com/kavu/go_reuseport) listener
-- Run a separate server instance per CPU core with `GOMAXPROCS=1` (it appears during benchmarks that there is a lot more context switches with Traefik than with nginx)

-
-### `onDemand`
-
-```toml

-Enable on demand certificate.
-
-This will request a certificate from Let's Encrypt during the first TLS handshake for a hostname that does not yet have a certificate.
-
-!!! warning
-    TLS handshakes will be slow when requesting a hostname certificate for the first time, this can leads to DoS attacks.
-    
-!!! warning
-    Take note that Let's Encrypt have [rate limiting](https://letsencrypt.org/docs/rate-limits)
-
-### `onHostRule`
-
-```toml
-[acme]
-# ...
-onHostRule = true
-# ...
-```
-
-Enable certificate generation on frontends Host rules.
-
-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`.
-
-### `caServer`
-
-```toml
-[acme]
-# ...
-caServer = "https://acme-staging.api.letsencrypt.org/directory"
-# ...
-```
-
-CA server to use.
-
-- Uncomment the line to run on the staging Let's Encrypt server.
-- Leave comment to go to prod.
-
-### `domains`
-
-```toml
-[acme]
-# ...
-[[acme.domains]]
-main = "local1.com"
-sans = ["test1.local1.com", "test2.local1.com"]

-main = "local3.com"
-[[acme.domains]]
-main = "local4.com"
-# ...
-```
-
-You can provide SANs (alternative domains) to each main domain.
-All domains must have A/AAAA records pointing to Traefik.
-
-!!! warning
-    Take note that Let's Encrypt have [rate limiting](https://letsencrypt.org/docs/rate-limits).
-
-Each domain & SANs will lead to a certificate request.

-
-## 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.

-# Kubernetes Ingress Backend
-
-Træfik can be configured to use Kubernetes Ingress as a backend configuration.
-
-See also [Kubernetes user guide](/user-guide/kubernetes). 
-
-
-## Configuration
-
-```toml

-# Kubernetes Ingress configuration backend
-################################################################
-
-# Enable Kubernetes Ingress configuration backend.
-[kubernetes]
-
-# Kubernetes server endpoint.
-#
-# Optional for in-cluster configuration, required otherwise.
-# Default: empty
-#
-# endpoint = "http://localhost:8080"
-
-# Bearer token used for the Kubernetes client configuration.
-#
-# Optional
-# Default: empty
-#
-# token = "my token"
-
-# Path to the certificate authority file.
-# Used for the Kubernetes client configuration.

-
-# Disable PassHost Headers.
-#
-# Optional
-# Default: false
-#
-# disablePassHostHeaders = true
-```
-
-### `endpoint`
-
-The Kubernetes server endpoint.
-
-When deployed as a replication controller in Kubernetes, Traefik will use the environment variables `KUBERNETES_SERVICE_HOST` and `KUBERNETES_SERVICE_PORT` to construct the endpoint.
-
-Secure token will be found in `/var/run/secrets/kubernetes.io/serviceaccount/token` and SSL CA cert in `/var/run/secrets/kubernetes.io/serviceaccount/ca.crt`
-
-The endpoint may be given to override the environment variable values.
-
-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 from localhost.
-
-### `labelselector`
-
-Ingress label selector to identify Ingress objects that should be processed.
-
-See [label-selectors](https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/#label-selectors) for details.
-
-
-## Annotations
-
-Annotations can be used on containers to override default behaviour for the whole Ingress resource:
-
-- `traefik.frontend.rule.type: PathPrefixStrip`  
-    Override the default frontend rule type. Default: `PathPrefix`.
-- `traefik.frontend.priority: 3`  
-    Override the default frontend rule priority.
-
-Annotations can be used on the Kubernetes service to override default behaviour:
-
-- `traefik.backend.loadbalancer.method=drr`  
-    Override the default `wrr` load balancer algorithm
-- `traefik.backend.loadbalancer.sticky=true`      
-    Enable backend sticky sessions
-
-You can find here an example [ingress](https://raw.githubusercontent.com/containous/traefik/master/examples/k8s/cheese-ingress.yaml) and [replication controller](https://raw.githubusercontent.com/containous/traefik/master/examples/k8s/traefik.yaml).
-
-Additionally, an annotation can be used on Kubernetes services to set the [circuit breaker expression](/basics/#backends) for a backend.
-
-- `traefik.backend.circuitbreaker: <expression>`  
-    Set the circuit breaker expression for the backend. Default: `nil`.
-
-As known from nginx when used as Kubernetes Ingress Controller, a list of IP-Ranges which are allowed to access can be configured by using an ingress annotation:
-
-- `ingress.kubernetes.io/whitelist-source-range: "1.2.3.0/24, fe80::/16"`
-
-An unset or empty list allows all Source-IPs to access.
-If one of the Net-Specifications are invalid, the whole list is invalid and allows all Source-IPs to access.
-
-
-### Authentication
-
-Is possible to add additional authentication annotations in the Ingress rule.
-The source of the authentication is a secret that contains usernames and passwords inside the the key auth.
-
-- `ingress.kubernetes.io/auth-type`: `basic`
-- `ingress.kubernetes.io/auth-secret`  
-    Contains the usernames and passwords with access to the paths defined in the Ingress Rule.
-
-The secret must be created in the same namespace as the Ingress rule.
-
-Limitations:
-
-- Basic authentication only.
-- Realm not configurable; only `traefik` default.
-- Secret must contain only single file.

-### 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.
-

-- `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.  
-**Note** You can use file path or cert content directly
-
-- `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
-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"
-```
-
-### 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.
-
-
-## Retry Configuration
-
-```toml
-# Enable retry sending request if network error
-[retry]
-
-# Number of attempts
-#

-# Default: (number servers in backend) -1

-
-## 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.
-
-## 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
-[forwardingTimeouts]
-
-# dialTimeout is the amount of time to wait until a connection to a backend server can be established.
-#
-# Optional
-# Default: "30s"
-#
-# dialTimeout = "30s"
-
-# responseHeaderTimeout is the amount of time to wait for a server's response headers after fully writing the request (including its body, if any).
-#
-# Optional
-# Default: "0s"
-#
-# responseHeaderTimeout = "0s"
-```
-
-- `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.
-
-- `responseHeaderTimeout` is the amount of time to wait for a server's response headers after fully writing the request (including its body, if any).  
-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.
-
-```toml
-# IdleTimeout
-#
-# DEPRECATED - see [respondingTimeouts] section.
-#
-# Optional
-# Default: "180s"
-#
-IdleTimeout = "360s"
-```
-
-
-## Override Default Configuration Template
-
-!!! warning
-    For advanced users only.
-
-Supported by all backends except: File backend, Web backend and DynamoDB backend.
-
-```toml
-[backend_name]
-
-# Override default configuration template. For advanced users :)
-#
-# Optional
-# Default: ""
-#
-filename = "custom_config_template.tpml"
-
-# Enable debug logging of generated configuration template.
-#
-# Optional
-# Default: false
-#
-debugLogGeneratedTemplate = true
-```
-
-Example:
-
-```toml
-[marathon]
-filename = "my_custom_config_template.tpml"
-```
-
-The template files can be written using functions provided by:
-
-- [go template](https://golang.org/pkg/text/template/)
-- [sprig library](https://masterminds.github.io/sprig/)
-
-Example:
-
-```tmpl
-[backends]
-  [backends.backend1]
-  url = "http://firstserver"
-  [backends.backend2]
-  url = "http://secondserver"
-
-{{$frontends := dict "frontend1" "backend1" "frontend2" "backend2"}}
-[frontends]
-{{range $frontend, $backend := $frontends}}
-  [frontends.{{$frontend}}]
-  backend = "{{$backend}}"
-{{end}}

-## 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]]

-      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"
-```
-
-## 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"
-```
-
-## TLS Mutual Authentication
-
-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.
-
-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]
-  ClientCAFiles = ["tests/clientca1.crt", "tests/clientca2.crt"]
-    [[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"

-## Authentication
-
-### 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
-# 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 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
-# 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.basic]
-  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 auth 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).
