This repository contains a template to deploy Traefik 2 using Docker Compose on a single machine running Docker.

• Docker
• Docker Compose
• Git
• Text editor of your choice (e.g. Vim)

Clone the repository:

$ git clone https://github.com/cedrichopf/traefik-dockerized.git
Cloning into 'traefik-dockerized'...

Create a copy of the example configuration files:

# Traefik Configuration
$ cp config/traefik.example.yml config/traefik.yml
# Custom Docker Compose Configuration
$ cp override.example.yml docker-compose.override.yml

To disable the Traefik Dashboard, change the following configuration value to false:

api:
  dashboard: false

Per default, this Traefik deployment listens on port 80 (HTTP) and 443 (HTTPS). This can be changed by adapting the address field of the Entry Points:

entryPoints:
  http:
    address: ":80"
  https:
    address: ":443"

To let Traefik auto-discover the applications running as a Docker container on the machine, create a Docker network and add it to the configuration. In this example, the Docker network is called proxy.

1. Create a Docker network:

$ docker network create proxy
ca0a9fe39b34b9f17d5c5e938e82ce67b4423e151ae5000eee7754e89116cac1

1. Add the network to the configuration:

providers:
  docker:
    network: proxy

To use the built-in Let's Encrypt support, add a Certificate Resolver to the configuration:

certificatesResolvers:
  letsencrypt:
    acme:
      email: [email protected]
      storage: acme.json
      httpChallenge:
        entryPoint: http

The file acme.json will be mounted inside the Traefik container and is used to store the certificates received from Let's Encrypt. Create this file and change the file permissions to 600:

$ touch letsencrypt/acme.json
$ chmod 600 letsencrypt/acme.json

If the Traefik Dashboard is enabled, configure the router in the docker-compose.override.yml file to make the dashboard available:

labels:
  - traefik.http.routers.traefik-http.rule=Host(`traefik.example.com`)
  - traefik.http.routers.traefik-http.entrypoints=http
  - traefik.http.routers.traefik-http.middlewares=redirect
  - traefik.http.routers.traefik-https.rule=Host(`traefik.example.com`)
  - traefik.http.routers.traefik-https.entrypoints=https
  - traefik.http.routers.traefik-https.tls=true
  - traefik.http.routers.traefik-http.service=api@internal
  - traefik.http.routers.traefik-https.service=api@internal
  - traefik.http.middlewares.redirect.redirectscheme.scheme=https

Once the configuration is completed, download the Docker images and start the services using docker-compose:

$ docker-compose pull
$ docker-compose up -d

To stop the deployment, you can either run the stop or down command of docker-compose:

$ docker-compose stop
Stopping traefik_traefik_1 ... done
$ docker-compose down
Stopping traefik_traefik_1 ... done
Removing traefik_traefik_1 ... done

By using docker-compose down instead of docker-compose stop, the containers will be also removed.

To update the Traefik instance, download the latest Docker images and recreate the services:

$ docker-compose pull
Pulling traefik ... done
$ docker-compose up -d
Recreating traefik_traefik_1 ... done

The command docker-compose pull will automatically fetch and download the latest version of Traefik available on Docker Hub. Finally, the command docker-compose up -d will recreate the running Traefik container with the latest version.
