Traefik 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. Pointing Traefik at your orchestrator should be the _only_ configuration step you need. ## 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!)_  ## 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 - Exposes a Rest API - Packaged as a single binary file (made with ❤️ with go) and available as a [tiny](https://microbadger.com/images/traefik) [official](https://hub.docker.com/r/_/traefik/) docker image ## Supported Providers - [Docker](/configuration/backends/docker/) / [Swarm mode](/configuration/backends/docker/#docker-swarm-mode) - [Kubernetes](/configuration/backends/kubernetes/) - [Mesos](/configuration/backends/mesos/) / [Marathon](/configuration/backends/marathon/) - [Rancher](/configuration/backends/rancher/) (API, Metadata) - [Azure Service Fabric](/configuration/backends/servicefabric/) - [Consul Catalog](/configuration/backends/consulcatalog/) - [Consul](/configuration/backends/consul/) / [Etcd](/configuration/backends/etcd/) / [Zookeeper](/configuration/backends/zookeeper/) / [BoltDB](/configuration/backends/boltdb/) - [Eureka](/configuration/backends/eureka/) - [Amazon ECS](/configuration/backends/ecs/) - [Amazon DynamoDB](/configuration/backends/dynamodb/) - [File](/configuration/backends/file/) - [Rest](/configuration/backends/rest/) ## Security ### Security Advisories We strongly advise you to join our mailing list to be aware of the latest announcements from our security team.
