Træfɪk is a modern HTTP reverse proxy and load balancer made to deploy microservices with ease.
It supports several backends ([Docker :whale:](https://www.docker.com/), [Mesos/Marathon](https://mesosphere.github.io/marathon/), [Consul](https://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.
## Features
- No dependency hell, single binary made with go
- Simple json Rest API
- Simple TOML file configuration
- Multiple backends supported: Docker, Mesos/Marathon, Consul, Etcd, and more to come
- Watchers for backends, can listen change in backends to apply a new configuration automatically
- Hot-reloading of configuration. No need to restart the process
- Graceful shutdown http connections during hot-reloads
- Circuit breakers on backends
- Round Robin, rebalancer load-balancers
- Rest Metrics
- Tiny docker image included
- SSL backends support
- SSL frontend support
- Clean AngularJS Web UI
- Websocket support
## Demo
Here is a demo of Træfɪk using Docker backend, showing a load-balancing between two servers, hot reloading of configuration, and graceful shutdown.

## Web UI
You can access to a simple HTML frontend of Træfik.

## Plumbing
- [Oxy](https://github.com/mailgun/oxy/): an awsome proxy library made by Mailgun guys
- [Gorilla mux](https://github.com/gorilla/mux): famous request router
- [Negroni](https://github.com/codegangsta/negroni): web middlewares made simple
- [Manners](https://github.com/mailgun/manners): graceful shutdown of http.Handler servers
## Quick start
- The simple way: grab the latest binary from the [releases](https://github.com/emilevauge/traefik/releases) page and just run it with the [sample configuration file](https://raw.githubusercontent.com/EmileVauge/traefik/master/traefik.sample.toml):
```shell
./traefik traefik.toml
```
- Use the tiny Docker image:
```shell
docker run -d -p 8080:8080 -p 80:80 -v $PWD/traefik.toml:/traefik.toml emilevauge/traefik
```
- From sources:
```shell
git clone https://github.com/EmileVauge/traefik
```

### 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 .

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/emilevauge/traefik/"dist":/go/src/github.com/emilevauge/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 up`** 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 up --update-vendored
# 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/emilevauge/traefik/dist" "traefik-dev:your-feature-branch" ./script/make.sh generate test-unit
