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 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.
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.
**This is when Træfik can help you!**
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.
**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!)_

## Quickstart
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).
Alternatively, if you don't want to install anything on your computer, you can try Træfik online in this great [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.
## Web UI
You can access the simple HTML frontend of Træfik.

## Release Cycle
- We release a new version (e.g. 1.1.0, 1.2.0, 1.3.0) every other month.
- Release Candidates are available before the release (e.g. 1.1.0-rc1, 1.1.0-rc2, 1.1.0-rc3, 1.1.0-rc4, before 1.1.0)
- Bug-fixes (e.g. 1.1.1, 1.1.2, 1.2.1, 1.2.3) are released as needed (no additional features are delivered in those versions, bug-fixes only)
Each version is supported until the next one is released (e.g. 1.1.x will be supported until 1.2.0 is out)
We use [Semantic Versioning](http://semver.org/)
