Bug

What did you do?

I've been using traefik on Swarm for serving gitlab registry and gitlab git service be on the same container for a while, but as of 1.6.5 i'm unable to access either service or wrong redirection to a specfic service, reason i'm staying in 1.6.0 for now.

What did you expect to see?

Be able to access both services gitlab.domain.com and registry.domain.com

What did you see instead?

Unable to access either service, or access Git service at registry.domain.com and Registry at gitlab.domain.com

Output of traefik version: (What version of Traefik are you using?)

Version:      v1.6.5
Codename:     tetedemoine
Go version:   go1.10.3
Built:        2018-07-10_03:54:03PM
OS/Arch:      linux/arm

What is your environment & configuration (arguments, toml, provider, platform, ...)?

• Docker v17.12.1

• GitLab image is a monolithic with all the services into it, both of the services (Registry and Git) need to be served in the same container, following is the docker compose file definition i use for it.

Screenshots

If this is useful, when using traefik 1.6.5, it only creates a single backend for both services

But 1.6.0 creates one for each of them

[ldez]

could you remove - "traefik.backend=gitlab"

Alright, that did the trick, so sorry for the noise.

@ulm0 I'm trying to get exactly what you have done: I'm running a working gitlab and I added a registry, but the registry just returns 502 error. Could you please show how you set up the gitlab service in your docker-compose?

This is how I've tried it:

version: '3.3'

services:
  gitlab:
    image: gitlab/gitlab-ce:latest
    container_name: gitlab
    environment:
      GITLAB_OMNIBUS_CONFIG: |
        external_url = 'https://gitlab.domain.com'
        registry_external_url = 'https://registry.domain.com'
        gitlab_rails['gitlab_shell_ssh_port'] = 2222
        gitlab_rails['registry_enabled'] = true
    ports:
      - '2222:22'
      - '5001:5001'
    networks:
      - proxy
    labels:
      - traefik.enable=true
      - traefik.gitlab.frontend.rule=Host:gitlab.domain.com
      - traefik.gitlab.port=80
      - traefik.reg.frontend.rule=Host:registry.domain.com
      - traefik.reg.port=5001
      - traefik.docker.network=proxy

networks:
  proxy:
    external: true
