Docker Gitlab doesnt work with traefik proxy

Hi
I tried to add gitlab.localhost domain to gitlab. My other services - whoami, jenkins, artifactory work well, but gitlab doesnt. Container is up but Im getting “internal server error”. I tried many different things from google but it just doesnt work with gitlab.localhost domain. But offcourse with default setup (localhost.8929) works well.

Seriously? No one will help?

I see you went from traefik 1.x to traefik 2.x and just commented out the old labels.
With traefik 2, the gitlab config is missing some labels (entrypoint, service and service port)

labels:
      - "traefik.enable=true"
      - "traefik.http.routers.gitlab.entrypoints=http"
      - "traefik.http.routers.gitlab.rule=Host(`gitlab.localhost`)"
      - "traefik.http.routers.gitlab.service=gitlab"
      - "traefik.http.services.gitlab.loadbalancer.server.port=80"

@yacinelazaar With your settings im getting 404.

Your traefik entrypoint should be the same as configured with gitlab

  • “–entrypoints.web.address=:80” >> - “–entrypoints.http.address=:80”

Also im assuming you added the gitlab url as alias in /etc/hosts

Bad gateway now.

No i didnt anything there but as i previously said, 3 other services from this file work ok.

You mean Jenkins, Artifact and whomai are working fine?
Could you wait for gitlab to initialize?
Can you paste the modified setup?

can you uncomment this line

I strongly suggest you to run it by yourself.

Why did you change the external URL?

This works.
Adpat to your needs.
