traefik

This is a Docker container for a Traefik edge router. The official container and documentation was made by traefik. This docker-rebuild is made up by a docker-compose.yml file.

Set-up

Create the files rebuild.sh and docker-compose.yml at the same place. In that folder create the directories data/config. Place the files data/traefik.yml and data/config/dynamic.yml in the according directories. Change the settings according to your needs and run ./rebuild.sh afterwards. Additional guides on the usage of Traefik for Docker services can be found in the Traefik wiki entry.

Volumes

Set the following volumes in the volumes: section of the docker-compose file.

Outside mount/volume name	Container mount	Description
`/etc/localtime`	`/etc/localtime:ro`	get the system time
`/var/run/docker.sock`	`/var/run/docker.sock:ro`	get access to view docker container
`./data/traefik.yml`	`/traefik.yml:ro`	basic traefik config
`./data/acme.json`	`/acme.json`	place to store certificates for https
`./data/config`	`/configurations`	place for dynamically changable configs

Ports

Set the following ports in the ports: section.

Container Port	Recommended outside port	Protocol	Description
`80`	`80`	TCP	http
`443`	`443`	TCP	https

Networks

Set the following networks in the networks: section of the docker-compose file.

Name	Usage
`proxy`	network to expose http and https ports

Labels

Set the following labels in the labels: section.

  - "traefik.enable=true"
  - "traefik.docker.network=proxy"
  - "traefik.http.routers.traefik-secure.entrypoints=websecure"
  - "traefik.http.routers.traefik-secure.service=api@internal"
  - "traefik.http.routers.traefik-secure.rule=Host(`traefik.<domain>`)"
  - "traefik.http.routers.traefik-secure.middlewares=user-auth@file"

The first five lines are for publishing traefik under traefik.<domain>. The last line is to add authentication.
