Træfik (pronounced like _traffic_) 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.

Træfik is a modern HTTP reverse proxy and load balancer that makes deploying microservices easy.
|
||||
Træfik 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.
|
||||
Telling Træfik where your orchestrator is could be the _only_ configuration step you need to do.

## 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.
|
||||
|
||||
Microservices are often deployed in dynamic environments where services are added, removed, killed, upgraded or scaled many times a day.
|
||||
**This is when Træfik can help you!**
|
||||
|
||||
Traditional reverse-proxies are not natively dynamic. You can't change their configuration and hot-reload easily.
|
||||
Træfik 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.
|
||||
**Run Træfik and let it do the work for you!**
|
||||
_(But if you'd rather configure some of your routes manually, Træfik supports that too!)_
|
||||
|
||||
|
||||
|
||||
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.
|
||||
To get your hands on Træfik, you can use the [5-Minute Quickstart](http://docs.traefik.io/#the-trfik-quickstart-using-docker) in our documentation (you will need Docker).

## 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
