Nell'host di destinazione, avvio un nuovo container GitLab:

docker run --detach --hostname --publish 443:443 --publish 80:80 --publish 22:22 --name gitlab  --restart always  --volume /srv/gitlab/config:/etc/gitlab  --volume /srv/gitlab/logs:/var/log/gitlab  --volume /srv/gitlab/data:/var/opt/gitlab  gitlab/gitlab-ce:10.8.4-ce.0

Copio gitlab.rb dalla sorgente alla destinazione /srv/gitlab/config/gitlab.rb

Nell'host di destinazione, riconfiguro gitlab con il nuovo gitlab.rb:

docker exec -ti gitlab gitlab-ctl reconfigure
