GitLab Docker behind Traefik

Deploy a GitLab Docker deployment behind Traefik as reverse proxy for all HTTP/S traffic. For more information see my blog post on migrating a GitLab omnibus deployment to Docker

docker-compose.yml

version: '3'

networks:
  web:
    external: true

services:
  # The reverse proxy service (Traefik)
  traefik:
    image: traefik  # The official Traefik docker image
    command: --api --docker  # Enables the web UI and tells Traefik to listen to docker
    restart: always
    networks:
    - web
    ports:
    - "80:80"
    - "443:443"
    # - "9000:9000"  # exposes the Traefik web UI
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock"  # So that Traefik can listen to the Docker events
      - "./traefik.toml:/traefik.toml"

thank's for this example - was helpful for me

Nice ! missed the nginx conf. Very helpful

Thank you! You were my lifesaver :)

Cheeeeeeeers, buuuuuud

Now that traefik support TCP routing, how would it look like now?
