Træfik, a modern reverse proxy https://traefik.io
Træfik is a modern HTTP reverse proxy and load balancer that makes deploying microservices easy. Træfik integrates with your existing infrastructure components (Docker, Swarm mode, Kubernetes, Marathon, Consul, Etcd, Rancher, Amazon ECS, ...) and configures itself automatically and dynamically. Telling Træfik where your orchestrator is could be the onlyconfiguration step you need to do.
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 eachmicroservice. 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 (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 ... which is nice
- Exposes a Rest API
- Packaged as a single binary file (made with
❤️ with go) and available as a tiny official docker image
Supported Backends

- Rest
Quickstart
To get your hands on Træfik, you can use the 5-Minute Quickstart 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 tutorialthat 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 to see how to load balance between multiple nodes.
Web UI
You can access the simple HTML frontend of Træfik.
