Traefik is a modern HTTP reverse proxy and load balancer that makes deploying microservices easy.

Traefik integrates with your existing infrastructure components (Docker, Swarm mode, Kubernetes, Marathon, Consul, Etcd, Rancher, Amazon ECS, ...) and configures itself automatically and dynamically.

Pointing Traefik at your orchestrator should be the only configuration step you need.

Traefik v2 - Example usage

Enable docker provider and web UI:

## traefik.yml

# Docker configuration backend
providers:
  docker:
    defaultRule: "Host(`{{ trimPrefix `/` .Name }}.docker.localhost`)"

# API and dashboard configuration
api:
  insecure: true

Start Traefik:

docker run -d -p 8080:8080 -p 80:80 \
-v $PWD/traefik.yml:/etc/traefik/traefik.yml \
-v /var/run/docker.sock:/var/run/docker.sock \
traefik:v2.0

Start a backend server, named test:

docker run -d --name test containous/whoami

And finally, you can access to your whoami server throught Traefik, on the domain name test.docker.localhost:

# $ curl --header 'Host:test.docker.localhost' 'http://localhost:80/'
$ curl test.docker.localhost
Hostname: 390a880bdfab
IP: 127.0.0.1
IP: 172.17.0.3
GET / HTTP/1.1
Host: test.docker.localhost
User-Agent: curl/7.65.3
Accept: */*
Accept-Encoding: gzip
X-Forwarded-For: 172.17.0.1
X-Forwarded-Host: test.docker.localhost
X-Forwarded-Port: 80
X-Forwarded-Proto: http
X-Forwarded-Server: 7e073cb54211
X-Real-Ip: 172.17.0.1

The web UI http://localhost:8080 will give you an overview of the routers, services, and middlewares.

Traefik v1 - Example usage

Grab a sample configuration file and rename it to traefik.toml. Enable docker provider and web UI:

## traefik.toml

# API and dashboard configuration
[api]

# Docker configuration backend
[docker]
  domain = "docker.localhost"

Start Traefik:

docker run -d -p 8080:8080 -p 80:80 \
-v $PWD/traefik.toml:/etc/traefik/traefik.toml \
-v /var/run/docker.sock:/var/run/docker.sock \
traefik:v1.7

Start a backend server, named test:

docker run -d --name test containous/whoami

And finally, you can access to your whoami server throught Traefik, on the domain name {containerName}.{configuredDomain} (test.docker.localhost):

# $ curl --header 'Host:test.docker.localhost' 'http://localhost:80/'
$ curl 'http://test.docker.localhost'
Hostname: 117c5530934d
IP: 127.0.0.1
IP: ::1
IP: 172.17.0.3
IP: fe80::42:acff:fe11:3
GET / HTTP/1.1
Host: test.docker.localhost
User-Agent: curl/7.35.0
Accept: */*
Accept-Encoding: gzip
X-Forwarded-For: 172.17.0.1
X-Forwarded-Host: 172.17.0.3:80
X-Forwarded-Proto: http
X-Forwarded-Server: f2e05c433120

The web UI http://localhost:8080 will give you an overview of the frontends/backends and also a health dashboard.

Image Variants

The traefik images come in many flavors, each designed for a specific use case.

`traefik:<version>`

This is the defacto image. If you are unsure about what your needs are, you probably want to use this one. It is designed to be used both as a throw away container (mount your source code and start the container to start your app), as well as the base to build other images off of.

`traefik:<version>-windowsservercore`

This image is based on Windows Server Core (microsoft/windowsservercore). As such, it only works in places which that image does, such as Windows 10 Professional/Enterprise (Anniversary Edition) or Windows Server 2016.

For information about how to get Docker running on Windows, please see the relevant "Quick Start" guide provided by Microsoft:
