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!)_ ![Architecture](docs/img/architecture.png) ## 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) (wildcard certificates support) - 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](https://docs.traefik.io/configuration/backends/docker) / [Swarm mode](https://docs.traefik.io/configuration/backends/docker#docker-swarm-mode) - [Kubernetes](https://docs.traefik.io/configuration/backends/kubernetes) - [Mesos](https://docs.traefik.io/configuration/backends/mesos) / [Marathon](https://docs.traefik.io/configuration/backends/marathon) - [Rancher](https://docs.traefik.io/configuration/backends/rancher) (API, Metadata) - [Azure Service Fabric](https://docs.traefik.io/configuration/backends/servicefabric) - [Consul Catalog](https://docs.traefik.io/configuration/backends/consulcatalog) - [Consul](https://docs.traefik.io/configuration/backends/consul) / [Etcd](https://docs.traefik.io/configuration/backends/etcd) / [Zookeeper](https://docs.traefik.io/configuration/backends/zookeeper) / [BoltDB](https://docs.traefik.io/configuration/backends/boltdb) - [Eureka](https://docs.traefik.io/configuration/backends/eureka) - [Amazon ECS](https://docs.traefik.io/configuration/backends/ecs) - [Amazon DynamoDB](https://docs.traefik.io/configuration/backends/dynamodb) - [File](https://docs.traefik.io/configuration/backends/file) - [Rest](https://docs.traefik.io/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. ![Web UI Providers](docs/img/web.frontend.png) ![Web UI Health](docs/img/traefik-health.png) ## Documentation You can find the complete documentation at [https://docs.traefik.io](https://docs.traefik.io).
