Instead of using bind-mounts for the data/config/log volumes in the gitlab container, which apparently caused the problem, I switched to docker volumes.

Did not work volumes:

• ./gitlab/config:/etc/gitlab’
• ./gitlab/data:/var/log/gitlab’

Worked volumes: - gitlab-config:/etc/gitlab - gitlab-data:/var/opt/gitlab

volumes: gitlab-runner: driver: local gitlab-config: driver: local gitlab-logs: driver: local gitlab-data: driver: local
