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](#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 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!)_  ## Features - Continuously updates its configuration (No restarts!) - Supports multiple load balancing algorithms - Provides HTTPS to your microservices by leveraging [Let's Encrypt](https://letsencrypt.org) - Circuit breakers, retry - High Availability with cluster mode (beta) - See the magic through its clean web UI - Websocket, HTTP/2, GRPC ready - Provides metrics (Rest, Prometheus, Datadog, Statsd, InfluxDB) - Keeps access logs (JSON, CLF) - [Fast](https://docs.traefik.io/benchmarks) ... which is nice - Exposes a Rest API - Packaged as a single binary file (made with :heart: with go) and available as a [tiny](https://microbadger.com/images/traefik) [official](https://hub.docker.com/r/_/traefik/) docker image ## Supported Backends - [Docker](docs/configuration/backends/docker/) / [Swarm mode](docs/configuration/backends/docker/#docker-swarm-mode) - [Kubernetes](docs/configuration/backends/kubernetes/) - [Mesos](docs/configuration/backends/mesos/) / [Marathon](docs/configuration/backends/marathon/) - [Rancher](docs/configuration/backends/rancher/) (API, Metadata) - [Service Fabric](docs/configuration/backends/servicefabric/) - [Consul Catalog](docs/configuration/backends/consulcatalog/) - [Consul](docs/configuration/backends/consul/) / [Etcd](docs/configuration/backends/etcd/) / [Zookeeper](docs/configuration/backends/zookeeper/) / [BoltDB](docs/configuration/backends/boltdb/) - [Eureka](docs/configuration/backends/eureka/) - [Amazon ECS](docs/configuration/backends/ecs/) - [Amazon DynamoDB](docs/configuration/backends/dynamodb/) - [File](docs/configuration/backends/file/) - [Rest](docs/configuration/backends/rest/) ## 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.   ## Documentation You can find the complete documentation at [https://docs.traefik.io](https://docs.traefik.io). A collection of contributions around Træfik can be found at [https://awesome.traefik.io](https://awesome.traefik.io). ## Support To get community support, you can: - join the Træfik community Slack channel: [](https://traefik.herokuapp.com) - use [Stack Overflow](https://stackoverflow.com/questions/tagged/traefik) (using the `traefik` tag) If you need commercial support, please contact [Containo.us](https://containo.us) by mail: . ## Download - Grab the latest binary from the [releases](https://github.com/containous/traefik/releases) page and run it with the [sample configuration file](https://raw.githubusercontent.com/containous/traefik/master/traefik.sample.toml): ```shell ./traefik --configFile=traefik.toml ``` - Or use the official tiny Docker image and 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 ``` - Or get the sources: ```shell git clone https://github.com/containous/traefik ``` ## Introductory Videos Here is a talk given by [Emile Vauge](https://github.com/emilevauge) at [GopherCon 2017](https://gophercon.com/).
