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](#overview)** . **[Features](#features)** . **[Supported backends](#supported-backends)** . **[Quickstart](#quickstart)** . **[Web UI](#web-ui)** . **[Test it](#test-it)** . **[Documentation](#documentation)** . . **[Support](#support)** . **[Release cycle](#release-cycle)** . **[Contributing](#contributing)** . **[Maintainers](#maintainers)** . **[Plumbing](#plumbing)** . **[Credits](#credits)** . --- ## 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 Microservices are often deployed in dynamic environments where services are added, removed, killed, upgraded or scaled many 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! ## Features - [It's fast](https://docs.traefik.io/benchmarks) - No dependency hell, single binary made with go - [Tiny](https://microbadger.com/images/traefik) [official](https://hub.docker.com/r/_/traefik/) docker image - Rest API - Hot-reloading of configuration.

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.
