Traefik (pronounced _traffic_) is a modern HTTP reverse proxy and load balancer that makes deploying microservices easy.

Traefik integrates with your existing infrastructure components ([Docker](https://www.docker.com/), [Swarm mode](https://docs.docker.com/engine/swarm/), [Kubernetes](https://kubernetes.io), [Consul](https://www.consul.io/), [Etcd](https://coreos.com/etcd/), [Rancher v2](https://rancher.com), [Amazon ECS](https://aws.amazon.com/ecs), ...) and configures itself automatically and dynamically.

Pointing Traefik at your orchestrator should be the _only_ configuration step you need.

:warning: When migrating to a new major version of Traefik, please refer to the [migration guide](https://doc.traefik.io/traefik/migration/v2-to-v3/) to ensure a smooth transition and to be aware of any breaking changes.



## 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 Traefik can help you!**



Traefik 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 Traefik and let it do the work for you!** 

_(But if you'd rather configure some of your routes manually, Traefik supports that too!)_

## Release Cycle



- We usually release 3/4 new versions (e.g. 1.1.0, 1.2.0, 1.3.0) per year.

- 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](https://semver.org/).
