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.
|
|
It supports several backends ([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 a lot more) to manage its configuration automatically and dynamically.

## 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:
|
|
|
|
- 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
|
|
|
|
But a microservices architecture is dynamic... Services are added, removed, killed or upgraded often, eventually several times a day.
|
|
|
|
Traditional reverse-proxies are not natively dynamic. You can't change their configuration and hot-reload easily.
|
|
|
|
Here enters Træfik.
|
|
|
|
|
|
|
|
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!

## 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.

## Test it
|
|
|
|
- The simple way: grab the latest binary from the [releases](https://github.com/containous/traefik/releases) page and just run it with the [sample configuration file](https://raw.githubusercontent.com/containous/traefik/master/traefik.sample.toml):
|
|
|
|
```shell
|
|
./traefik --configFile=traefik.toml
|
|
```
|
|
|
|
- Use the tiny Docker image and just run it with the [sample configuration file](https://raw.githubusercontent.com/containous/traefik/master/traefik.sample.toml):
|
|
|
|
```shell
|
|
docker run -d -p 8080:8080 -p 80:80 -v $PWD/traefik.toml:/etc/traefik/traefik.toml traefik
|
|
```
|
|
|
|
- From sources:
|
|
|
|
```shell
|
|
git clone https://github.com/containous/traefik
