setting up gitlab as docker container with docker registry showing error 500

问题

I'm trying to running a Gitlab docker container in a Vagrant box. But I have some problems getting the docker registry running.

my docker-compose.yml

gitlab:
  container_name: gitlab
  image: gitlab/gitlab-ce:latest
  volumes:
  - /srv/gitlab/config:/etc/gitlab
  - /srv/gitlab/logs:/var/log/gitlab 
  - /srv/gitlab/data:/var/opt/gitlab
  - /srv/gitlab/logs/reconfigure:/var/log/gitlab/reconfigure
  restart: always
  hostname: 192.168.7.7
  ports:
    - 0.0.0.0:23:22
    - 0.0.0.0:80:80
    - 0.0.0.0:443:443
    - 0.0.0.0:5000:5000
    - 0.0.0.0:7443:7443

(port 23:22 is only because I start it in a vagrant box and the port is already used)
the gitlab itself is later available under the ip: 192.168.7.7

To activate the docker-registry I changed the /srv/gitlab/config/gitlab.rb to the following:

gitlab_rails['registry_enabled'] = true
gitlab_rails['registry_host'] = "192.168.7.7"
gitlab_rails['registry_port'] = "7443"
gitlab_rails['registry_api_url'] = "http://192.168.7.7:5000"

The container-registry is available after a new docker-compose up, but clicking on the button is sending me to the URL showing me a 500 error page
http://192.168.7.7/mygroup/myproject/container_registry
and with this error log:

Anyone knows this problem?

回答1:

The actual Registry is not included in Gitlab, it only serves as an authentication service. You will need to setup a separate container for the registry:

gitlab:
  [...]

registry:
  image: registry:2
  [...]
