gitlab in docker behind traefik proxy fails (usually)

Question

I have several web sites running in docker with LetsEncrypt credentials and routed via traefik. I would like to run a local gitlab-ce in docker similarly with LetsEncrypt an

Answer 1

i've used sameersbn's docker-compose and added the following docker-compose.override.yml in the same directory.

version: "2"

services:
    gitlab:
      labels:
        - "traefik.frontend.rule=Host:git.schulz.codes"
        - "traefik.port=80"
        - "traefik.enable=true"
        - "traefik.frontend.entryPoints=http,https"

this keeps working quiet nicely with the following traefik docker-compose

version: "2"

services:
  proxy:
    restart: always
    image: traefik
    container_name: traefik
    command: --web --docker --docker.domain=docker.localhost --logLevel=DEBUG
    ports:
      - "8080:8080"
      - "80:80"
      - "443:443"
    volumes:
      - ./traefik.toml:/etc/traefik/traefik.toml
      - /var/run/docker.sock:/var/run/docker.sock
      - ./data:/etc/traefik/acme:rw

and this traefik.toml

[entryPoints]
  [entryPoints.http]
  address = ":80"
    [entryPoints.http.redirect]
    entryPoint = "https"
  [entryPoints.https]
  address = ":443"
    [entryPoints.https.tls]
defaultEntryPoints = ["http", "https"]
[acme]
email = "yourmail@domain.com"
storageFile = "/etc/traefik/acme/acme.json"
entryPoint = "https"
OnHostRule = true
[[acme.domains]]
  main = "domain.com"
  sans = ["gitlab.domain.com"]
[web]
address = ":8080"
[docker]
endpoint = "unix:///var/run/docker.sock"
domain = "docker.localhost"
watch = true
exposedbydefault = true
