+# Contributing
+
+### Building
+
+You need either [Docker](https://github.com/docker/docker) and `make`, or `go` and `glide` in order to build traefik.
+
+#### Setting up your `go` environment
+
+- You need `go` v1.5
+- You need to set `export GO15VENDOREXPERIMENT=1` environment variable
+- You need `go-bindata` to be able to use `go generate` command (needed to build) : `go get github.com/jteeuwen/go-bindata/...`.
+- If you clone Træfɪk into something like `~/go/src/github.com/traefik`, your `GOPATH` variable will have to be set to `~/go`: export `GOPATH=~/go`.
+
+#### 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:1.5
+ ---> 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*
+```
+
+#### Using `glide`
+
+The idea behind `glide` is the following :
+
+- when checkout(ing) a project, **run `glide install`** to install
+  (`go get …`) the dependencies in the `GOPATH`.
+- if you need another dependency, import and use it in
+  the source, and **run `glide get github.com/Masterminds/cookoo`** to save it in
+  `vendor` and add it to your `glide.yaml`.
+
+```bash
+$ glide install
+# generate
+$ go generate
+# Simple go build
+$ go build
+# Using gox to build multiple platform
+$ gox "linux darwin" "386 amd64 arm" \
+    -output="dist/traefik_{{.OS}}-{{.Arch}}"
+# run other commands like tests
+$ go test ./...
+ok      _/home/vincent/src/github/vdemeester/traefik    0.004s
+```
+
+### Tests
+
+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 purpose, you can specifiy which tests to run by using:
+```
+# 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
+
+### Documentation
+
+The [documentation site](http://docs.traefik.io/) is built with [mkdocs](http://mkdocs.org/)
+
+First make sure you have python and pip installed
+
+```
+$ python --version
+Python 2.7.2
+$ pip --version
+pip 1.5.2
+```
+
+Then install mkdocs with pip
+
+```
+$ pip install mkdocs
+```
+
+To test documentaion localy run `mkdocs serve` in the root directory, this should start a server localy to preview your changes.
+
+```
+$ 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

-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), [Marathon](https://mesosphere.github.io/marathon/), [Consul](https://www.consul.io/), [Etcd](https://coreos.com/etcd/), [Rancher](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.

-:warning: Please be aware that the old configurations for Traefik v1.x are NOT compatible with the v2.x config as of now. If you're running v2, please ensure you are using a [v2 configuration](https://doc.traefik.io/traefik/).
+Træfɪk is a modern HTTP reverse proxy and load balancer made to deploy microservices with ease.
+It supports several backends ([Docker](https://www.docker.com/), [Swarm](https://docs.docker.com/swarm), [Mesos/Marathon](https://mesosphere.github.io/marathon/), [Kubernetes](http://kubernetes.io/), [Consul](https://www.consul.io/), [Etcd](https://coreos.com/etcd/), [Zookeeper](https://zookeeper.apache.org), [BoltDB](https://github.com/boltdb/bolt), Rest API, file...) to manage its configuration automatically and dynamically.
 
 ## Overview
 
-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.
+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:
 
-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. 
+- 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
 
-**This is when Traefik can help you!**
+But a microservices architecture is dynamic... Services are added, removed, killed or upgraded often, eventually several times a day.
 
-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. 
+Traditional reverse-proxies are not natively dynamic. You can't change their configuration and hot-reload easily.
 
-**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!)_
+Here enters Træfɪk.
+
+![Architecture](docs/img/architecture.png)
+
+Træfɪk 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!
+  
+  
 
-![Architecture](docs/content/assets/img/traefik-architecture.png)
 
 ## Features
 
-- Continuously updates its configuration (No restarts!)
-- Supports multiple load balancing algorithms
-- Provides HTTPS to your microservices by leveraging [Let's Encrypt](https://letsencrypt.org)  (wildcard certificates support)

+# Concepts
+
+Let's take our example from the [overview](https://docs.traefik.io/#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 Træfɪk 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 Træfɪk (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 Træfɪk.
+They can be defined using:
+
+- a port (80, 443...)
+- SSL (Certificates. Keys...)
+- 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`.
+
+## Frontends
+
+A frontend is a set of rules that forwards the incoming traffic from an entrypoint to a backend.
+Frontends can be defined using the following rules:
+
+- `Headers: Content-Type, application/json`: Headers adds a matcher for request header values. It accepts a sequence of key/value pairs to be matched.
+- `HeadersRegexp: Content-Type, application/(text|json)`: Regular expressions can be used with headers as well. It accepts a sequence of key/value pairs, where the value has regex support.
+- `Host: traefik.io, www.traefik.io`: Match request host with given host list.
+- `HostRegexp: traefik.io, {subdomain:[a-z]+}.traefik.io`: Adds a matcher for the URL hosts. It accepts templates with zero or more URL variables enclosed by `{}`. Variables can define an optional regexp pattern to be matched.
+- `Method: GET, POST, PUT`: Method adds a matcher for HTTP methods. It accepts a sequence of one or more methods to be matched.
+- `Path: /products/, /articles/{category}/{id:[0-9]+}`: Path adds a matcher for the URL paths. It accepts templates with zero or more URL variables enclosed by `{}`.
+- `PathStrip`: Same as `Path` but strip the given prefix from the request URL's Path.
+- `PathPrefix`: PathPrefix adds a matcher for the URL path prefixes. This matches if the given template is a prefix of the full URL path.
+- `PathPrefixStrip`: Same as `PathPrefix` but strip the given prefix from the request URL's Path.
+
+You can use multiple rules by separating them by `;`
+
+You can optionally enable `passHostHeader` to forward client `Host` header to the backend.
+
+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
+  priority = 10
+  entrypoints = ["https"] # overrides defaultEntryPoints
+    [frontends.frontend2.routes.test_1]
+    rule = "Host: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 = "Host: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"
+```
+
+### 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:
+
+```
+  [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`).
+
+## 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 is 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 if condition matches, CB enters Tripped state, where it responds with predefines code or redirects to another frontend.
+Once Tripped timer expires, CB enters Recovering state and resets all stats.
+In case if 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.
+
+## 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).
+
+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
+
+# Launch
+
+Træfɪk can be configured using a TOML file configuration, arguments, or both.
+By default, Træfɪk 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
+```
+
+Træfɪk uses the following precedence order. Each item takes precedence over the item below it:
+
+- arguments
+- configuration file
+- default
+
+It means that arguments overrides configuration file.
+Each argument is described in the help section:
+
+```bash
+$ traefik --help
+```

+
+## 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)

-# Building and Testing
-
-Compile and Test Your Own Traefik!
-{: .subtitle }
-
-So you want to build your own Traefik binary from the sources?
-Let's see how.
-
-## 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 `dep` dependency management tool is required.
-
-### Method 1: Using `Docker` and `Makefile`
-
-Run make with the `binary` target.
-This will create binaries for the Linux platform in the `dist` folder.
-
-In case when you run build on CI, you may probably want to run docker in non-interactive mode. To achieve that define `DOCKER_NON_INTERACTIVE=true` environment variable.
-
-```bash
-$ make binary
-docker build -t traefik-webui -f webui/Dockerfile webui
-Sending build context to Docker daemon  2.686MB
-Step 1/11 : FROM node:8.15.0
- ---> 1f6c34f7921c
-[...]
-Successfully built ce4ff439c06a
-Successfully tagged traefik-webui:latest
-[...]
-docker build  -t "traefik-dev:4475--feature-documentation" -f build.Dockerfile .
-Sending build context to Docker daemon    279MB
-Step 1/10 : FROM golang:1.14-alpine
- ---> f4bfb3d22bda
-[...]
-Successfully built 5c3c1a911277
-Successfully tagged traefik-dev:4475--feature-documentation
-docker run  -e "TEST_CONTAINER=1" -v "/var/run/docker.sock:/var/run/docker.sock" -it -e OS_ARCH_ARG -e OS_PLATFORM_ARG -e TESTFLAGS -e VERBOSE -e VERSION -e CODENAME -e TESTDIRS -e CI -e CONTAINER=DOCKER		 -v "/home/ldez/sources/go/src/github.com/traefik/traefik/"dist":/go/src/github.com/traefik/traefik/"dist"" "traefik-dev:4475--feature-documentation" ./script/make.sh generate binary
----> Making bundle: generate (in .)
-removed 'autogen/genstatic/gen.go'
-
----> Making bundle: binary (in .)
-
-$ ls dist/
-traefik*
-```
-
-The following targets can be executed outside Docker by setting the variable `PRE_TARGET` to an empty string (we don't recommend that):
-
-- `test-unit`
-- `test-integration`
-- `validate`
-- `binary` (the webUI is still generated by using Docker)
-
-ex:
-
-```bash
-PRE_TARGET= make test-unit
-```
-
-### Method 2: Using `go`
-
-Requirements:
-
-- `go` v1.14+
-- environment variable `GO111MODULE=on`
-- [go-bindata](https://github.com/containous/go-bindata) `GO111MODULE=off go get -u github.com/containous/go-bindata/...`
-
-!!! tip "Source Directory"
-
-    It is recommended that you clone Traefik into the `~/go/src/github.com/traefik/traefik` directory.
-    This is the official golang workspace hierarchy that will allow dependencies to be properly resolved.
-
-!!! note "Environment"
-
-    Set your `GOPATH` and `PATH` variable to be set to `~/go` via:
-
-    ```bash
-    export GOPATH=~/go
-    export PATH=$PATH:$GOPATH/bin
-    ```
-
-    For convenience, add `GOPATH` and `PATH` 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 an output similar to:
-
-    ```bash
-    GOARCH="amd64"
-    GOBIN=""
-    GOEXE=""
-    GOHOSTARCH="amd64"
-    GOHOSTOS="linux"
-    GOOS="linux"
-    GOPATH="/home/<yourusername>/go"
-    GORACE=""
-    ## ... and the list goes on
-    ```
-
-#### Build Traefik
-
-Once you've set up your go environment and cloned the source repository, you can build Traefik.
-
-Beforehand, you need to get [go-bindata](https://github.com/containous/go-bindata) (the first time) in order to be able to use the `go generate` command (which is part of the build process).
-
-```bash
-cd ~/go/src/github.com/traefik/traefik
-
-# Get go-bindata. (Important: the ellipses are required.)
-GO111MODULE=off go get github.com/containous/go-bindata/...
-```
-
-```bash
-# Generate UI static files
-rm -rf static/ autogen/; make generate-webui
-
-# required to merge non-code components into the final binary,
-# such as the web dashboard/UI
-go generate
-```
-
-```bash
-# Standard go build
-go build ./cmd/traefik
-```
-
-You will find the Traefik executable (`traefik`) in the `~/go/src/github.com/traefik/traefik` directory.
-
-## Testing
-
-### Method 1: `Docker` and `make`
-
-Run unit tests using the `test-unit` target.
-Run integration tests using the `test-integration` target.
-Run all tests (unit and integration) using the `test` 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/traefik/traefik/dist:/go/src/github.com/traefik/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/traefik/traefik   0.005s  coverage: 4.1% of statements
-
-Test success
-```
-
-For development purposes, you can specify which tests to run by using (only works the `test-integration` target):
-
-```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 using `$ go test ./...` which should return `ok`, similar to:
-
-```test
-ok      _/home/user/go/src/github/traefik/traefik    0.004s
-```
-
-Integration tests must be run from the `integration/` directory and require the `-integration` switch: `$ cd integration && go test -integration ./...`.

-# Data Collection
-
-Understanding How Traefik is Being Used
-{: .subtitle }
-
-## Configuration Example
-
-Understanding how you use Traefik is very important to us: it helps us improve the solution in many different ways.  
-For this very reason, the sendAnonymousUsage option is mandatory: we want you to take time to consider whether or not you wish to share anonymous data with us so we can benefit from your experience and use cases.
-
-!!! example "Enabling Data Collection"
-    
-    ```toml tab="File (TOML)"
-    [global]
-      # Send anonymous usage data
-      sendAnonymousUsage = true
-    ```
-    
-    ```yaml tab="File (YAML)"
-    global:
-      # Send anonymous usage data
-      sendAnonymousUsage: true
-    ```
-    
-    ```bash tab="CLI"
-    # Send anonymous usage data
-    --global.sendAnonymousUsage
-    ```
-
-## Collected Data
-
-This feature comes from the public proposal [here](https://github.com/traefik/traefik/issues/2369).
-
-In order to help us learn more about how Traefik 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 important for our users (for example, which provider is popular, and which is not).
-
-### What's collected / when ?
-
-Once a day (the first call begins 10 minutes after the start of Traefik), we collect:
-
-- the Traefik version number
-- a hash of the configuration
-- an **anonymized version** of the static configuration (token, user name, password, URL, IP, domain, email, etc, are removed).
-
-!!! info
-    
-    - We do not collect the dynamic configuration information (routers & services).
-    - We do not collect this data to run advertising programs.
-    - We do not sell this data to third-parties.
-
-### Example of Collected Data
-
-```toml tab="Original configuration"
-[entryPoints]
-  [entryPoints.web]
-    address = ":80"
-
-[api]
-
-[providers.docker]
-  endpoint = "tcp://10.10.10.10:2375"
-  exposedByDefault = true
-  swarmMode = true
-
-  [providers.docker.TLS]
-    ca = "dockerCA"
-    cert = "dockerCert"
-    key = "dockerKey"
-    insecureSkipVerify = true
-```
-
-```toml tab="Resulting Obfuscated Configuration"
-[entryPoints]
-  [entryPoints.web]
-    address = ":80"
-
-[api]
-
-[providers.docker]
-  endpoint = "xxxx"
-  exposedByDefault = true
-  swarmMode = true
-
-  [providers.docker.TLS]
-    ca = "xxxx"
-    cert = "xxxx"
-    key = "xxxx"
-    insecureSkipVerify = true
-```
-
-## The Code for Data Collection
-
-If you want to dig into more details, here is the source code of the collecting system: [collector.go](https://github.com/traefik/traefik/blob/master/pkg/collector/collector.go)
-
-By default we anonymize all configuration fields, except fields tagged with `export=true`.

-# Documentation
-
-Features Are Better When You Know How to Use Them
-{: .subtitle }
-
-You've found something unclear in the documentation and want to give a try at explaining it better?
-Let's see how.
-
-## Building Documentation
-
-### General
-
-This [documentation](https://doc.traefik.io/traefik/) is built with [mkdocs](https://mkdocs.org/).
-
-### Method 1: `Docker` and `make`
-
-You can build the documentation and test it locally (with live reloading), using the `docs` target:
-
-```bash
-$ make docs
-docker build -t traefik-docs -f docs.Dockerfile .
-# […]
-docker run  --rm -v /home/user/go/github/traefik/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
-```
-
-!!! tip "Default URL"
-
-    Your local documentation server will run by default on [http://127.0.0.1:8000](http://127.0.0.1:8000).
-
-If you only want to build the documentation without serving it locally, you can use the following command:
-
-```bash
-$ make docs-build
-...
-```
-
-### Method 2: `mkdocs`
-
-First, make sure you have `python` and `pip` installed.
-
-```bash
-$ python --version
-Python 2.7.2
-$ pip --version
-pip 1.5.2
-```
-
-Then, install mkdocs with `pip`.
-
-```bash
-pip install --user -r requirements.txt
-```
-
-To build the documentation locally and serve it locally, run `mkdocs serve` from the root directory.
-This will start a local server.
-
-```bash
-$ mkdocs serve
-INFO    -  Building documentation...
-INFO    -  Cleaning site directory
-[I 160505 22:31:24 server:281] Serving on http://127.0.0.1:8000
-[I 160505 22:31:24 handlers:59] Start watching changes
-[I 160505 22:31:24 handlers:61] Start detecting changes
-```
-
-### Check the Documentation
-
-To check that the documentation meets standard expectations (no dead links, html markup validity, ...), use the `docs-verify` target.
-
-```bash
-$ make docs-verify
-docker build -t traefik-docs-verify ./script/docs-verify-docker-image ## Build Validator image
-...
-docker run --rm -v /home/travis/build/traefik/traefik:/app traefik-docs-verify ## Check for dead links and w3c compliance
-=== Checking HTML content...
-Running ["HtmlCheck", "ImageCheck", "ScriptCheck", "LinkCheck"] on /app/site/basics/index.html on *.html...
-```
-
-!!! note "Clean & Verify"
-
-    If you've made changes to the documentation, it's safter to clean it before verifying it. 
-
-    ```bash
-    $ make docs-clean docs-verify
-    ...
-    ```
-
-!!! note "Disabling Documentation Verification"
-
-    Verification can be disabled by setting the environment variable `DOCS_VERIFY_SKIP` to `true`:
-    
-    ```shell
-    DOCS_VERIFY_SKIP=true make docs-verify
-    ...
-    DOCS_LINT_SKIP is true: no linting done.
-    ```

-## Contributions Daily Meeting
-
-* 3 Maintainers should attend to a Contributions Daily Meeting where we sort and label new issues ([is:issue label:status/0-needs-triage](https://github.com/traefik/traefik/issues?utf8=%E2%9C%93&q=is%3Aissue+label%3Astatus%2F0-needs-triage+)), and review every Pull Requests
-* Every pull request should be checked during the Contributions Daily Meeting
-    * Even if it’s already assigned
-    * Even PR labelled with `contributor/waiting-for-corrections` or `contributor/waiting-for-feedback`
-* Issues labeled with `priority/P0` and `priority/P1` should be assigned.
-* Modifying an issue or a pull request (labels, assignees, milestone) is only possible:
-    * During the Contributions Daily Meeting
-    * By an assigned maintainer
-    * In case of emergency, if a change proposal is approved by 2 other maintainers (on Slack, Discord, Discourse, etc)
-
-## PR review process:
-
-* The status `needs-design-review` is only used in complex/heavy/tricky PRs.
-* From `1` to `2`: 1 comment that says “design LGTM” (by a senior maintainer).
-* From `2` to `3`: 3 LGTM approvals by any maintainer.
-* If needed, a specific maintainer familiar with a particular domain can be requested for the review.
-* If a PR has been implemented in pair programming, one peer's LGTM goes into the review for free
-* Amending someone else's pull request is authorized only in emergency, if a rebase is needed, or if the initial contributor is silent
-
-We use [PRM](https://github.com/ldez/prm) to manage locally pull requests.
-
-## Bots
-
-### [Myrmica Lobicornis](https://github.com/traefik/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.
-To preserve commits, add `bot/merge-method-rebase` before `status/3-needs-merge`.
-
-The status `status/4-merge-in-progress` is only used by the bot.
-
-If the bot is not able to perform the merge, the label `bot/need-human-merge` is added.  
-In such a situation, solve the conflicts/CI/... and then remove the label `bot/need-human-merge`.
-
-To prevent the bot from automatically merging a PR, add the label `bot/no-merge`.
-
-The label `bot/light-review` decreases the number of required LGTM from 3 to 1.
-
-This label is used when:
-
-* Updating the vendors from previously reviewed PRs
-* Merging branches into the master
-* Preparing the release
-
-### [Myrmica Bibikoffi](https://github.com/traefik/bibikoffi/)
-
-* closes stale issues [cron]
-    * use some criterion as number of days between creation, last update, labels, ...
-
-### [Myrmica Aloba](https://github.com/traefik/aloba)
-
-Manage GitHub labels.
-
-* Add labels on new PR [GitHub WebHook]
-* Add milestone to a new PR based on a branch version (1.4, 1.3, ...) [GitHub WebHook]
-* Add and remove `contributor/waiting-for-corrections` label when a review request changes [GitHub WebHook]
-* Weekly report of PR status on Slack (CaptainPR) [cron]
-
-## Labels
-
-A maintainer that looks at an issue/PR must define its `kind/*`, `area/*`, and `status/*`.
-
-### Status - Workflow
-
-The `status/*` labels represent the desired state in the workflow.
-
-* `status/0-needs-triage`: all the new issues and PRs have this status. _[bot only]_

-# Submitting Issues
-
-Help Us Help You!
-{: .subtitle }
-
-We use the [GitHub issue tracker](https://github.com/traefik/traefik/issues) to keep track of issues in Traefik. 
-
-The process of sorting and checking the issues is a daunting task, and requires a lot of work (more than an hour a day ... just for sorting).
-To save us some time and get quicker feedback, be sure to follow the guide lines below.
-
-!!! important "Getting Help Vs Reporting an Issue"
-
-    The issue tracker is not a general support forum, but a place to report bugs and asks for new features.
-
-    For end-user related support questions, try using first:
-
-    - the Traefik community forum: [![Join the chat at https://community.traefik.io/](https://img.shields.io/badge/style-register-green.svg?style=social&label=Discourse)](https://community.traefik.io/)
-
-## Issue Title
-
-The title must be short and descriptive. (~60 characters)
-
-## Description
-
-Follow the [issue template](https://github.com/traefik/traefik/blob/master/.github/ISSUE_TEMPLATE.md) as much as possible.
-
-Explain us in which conditions you encountered the issue, what is your context.
-
-Remain as clear and concise as possible
-
-Take time to polish the format of your message so we'll enjoy reading it and working on it. 
-Help the readers focus on what matters, and help them understand the structure of your message (see the [Github Markdown Syntax](https://help.github.com/articles/github-flavored-markdown)).
-
-## Feature Request
-
-Traefik is an open-source project and aims to be the best edge router possible.
-
-Remember when asking for new features that these must be useful to the majority (and not only useful in edge case scenarios, or hack-like setups).
-
-Do you best to explain what you're looking for, and why it would improve Traefik for everyone. 
-
-## International English
-
-Every maintainer / Traefik user is not a native English speaker, so if you feel sometimes that some messages sound rude, remember that it probably is a language barrier problem from someone willing to help you.
