Træfɪk

Træfɪk is a modern HTTP reverse proxy and load balancer made to deploy microservices with ease. It supports several backends (Docker, Swarm, Kubernetes, Marathon, Mesos, Consul, Etcd, Zookeeper, BoltDB, Eureka, Rest API, file...) to manage its configuration automatically and dynamically.

Overview

Imagine that you have deployed a bunch of microservices on your infrastructure. You probably used a service registry (like etcd or consul) and/or an orchestrator (swarm, Mesos/Marathon) to manage all these services. If you want your users to access some of your microservices from the Internet, you will have to use a reverse proxy and configure it using virtual hosts or prefix paths:

  • domain api.domain.com will point the microservice api in your private network
  • path domain.com/web will point the microservice web in your private network
  • domain backoffice.domain.com will point the microservices backoffice in your private network, load-balancing between your multiple instances

But a microservices architecture is dynamic... Services are added, removed, killed or upgraded often, eventually several times a day.

Traditional reverse-proxies are not natively dynamic. You can't change their configuration and hot-reload easily.

Here enters Træfɪk.

Architecture

Træfɪk can listen to your service registry/orchestrator API, and knows each time a microservice is added, removed, killed or upgraded, and can generate its configuration automatically. Routes to your services will be created instantly.

Run it and forget it!

Features

  • It's fast
  • No dependency hell, single binary made with go
  • Rest API
  • Multiple backends supported: Docker, Swarm, Kubernetes, Marathon, Mesos, Consul, Etcd, and more to come
  • Watchers for backends, can listen for changes in backends to apply a new configuration automatically
  • Hot-reloading of configuration. No need to restart the process
  • Graceful shutdown http connections
  • Circuit breakers on backends
  • Round Robin, rebalancer load-balancers
  • Rest Metrics
  • Tiny official docker image included
  • SSL backends support
  • SSL frontend support (with SNI)
  • Clean AngularJS Web UI
  • Websocket support
  • HTTP/2 support
  • Retry request if network error
  • Let's Encrypt support (Automatic HTTPS with renewal)
  • High Availability with cluster mode

Quickstart

You can have a quick look at Træfɪk in this Katacoda tutorial that shows how to load balance requests between multiple Docker containers.

Here is a talk given by Ed Robinson at the ContainerCamp UK conference. You will learn fundamental Træfɪk features and see some demos with Kubernetes.
