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
|
||
- WebUI
|
||
|
||
## Demo
|
||
|
||
Here is a demo of Træfɪk using Docker backend, showing a load-balancing between two servers, hot reloading of configuration, and graceful shutdown.

|
||
|
||
## 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 `godep` in order to build traefik.
|
||
|
||
#### Using Docker and Makefile
|
||
|
||
You need to run the `binary` target. This will create binaries for
|
||
linux and darwin platforms in the `dist` folder.
|
||
|
||
```bash
|
||
$ make binary
|
||
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 binary
|
||
---> Making bundle: generate (in .)
|
||
removed 'gen.go'
|
||
|
||
---> Making bundle: binary (in .)
|
||
Number of parallel builds: 8
|
||
|
||
--> linux/arm: github.com/emilevauge/traefik
|
||
--> darwin/amd64: github.com/emilevauge/traefik
|
||
--> darwin/386: github.com/emilevauge/traefik
|
||
--> linux/386: github.com/emilevauge/traefik
|
||
--> linux/amd64: github.com/emilevauge/traefik
|
||
|
||
$ ls dist/
|
||
traefik* traefik_darwin-386* traefik_darwin-amd64* traefik_linux-386* traefik_linux-amd64* traefik_linux-arm*
|
||
```
|
||
|
||
#### Using `godep`
|
||
|
||
The idea behind `godep` is the following :
|
||
|
||
- when checkout(ing) a project, **run `godep restore`** to install
|
||
(`go get …`) the dependencies in the `GOPATH`.
|
||
- if you need another dependency, `go get` it, import and use it in
|
||
the source, and **run `godep save ./...`** to save it in
|
||
`Godeps/Godeps.json`.
|
||
|
||
```bash
|
||
$ godep restore
|
||
# Generate
|
||
$ godep go generate
|
||
# Simple go build
|
||
$ godep go build
|
||
# Using gox to build multiple platform
|
||
$ GOPATH=`godep path`:$GOPATH gox "linux darwin" "386 amd64 arm" \
|
||
-output="dist/traefik_{{.OS}}-{{.Arch}}"
|
||
# run other commands like tests
|
||
$ godep 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
|
||
---> Making bundle: generate (in .)
|
||
removed 'gen.go'
|
||
|
||
---> Making bundle: test-unit (in .)
|
||
+ go test -cover -coverprofile=cover.out .
|
||
ok github.com/emilevauge/traefik 0.005s coverage: 4.1% of statements
|
||
|
||
Test success
