Docker Gitlab doesnt work with traefik proxy

doman18 · December 10, 2019, 2:42pm

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?

yacinelazaar · December 19, 2019, 12:54pm

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"

doman18 · December 19, 2019, 1:26pm

@yacinelazaar With your settings im getting 404.

yacinelazaar · December 19, 2019, 1:31pm

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

doman18 · December 19, 2019, 1:46pm

Bad gateway now.

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

yacinelazaar · December 19, 2019, 2:04pm

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

yacinelazaar · December 19, 2019, 2:11pm

can you uncomment this line

# nginx['listen_port'] = 80

I strongly suggest you to run it by yourself.

Why did you change the external URL?

This works.
Adpat to your needs.
