Moved Gitlab server to another host
I use the Gitlab Community Edition for private projects.
Now I wanted to replace the Acer Revo with a more powerful Intel NUC i5 I bought. So I copied all volumes referenced by the docker container (for me it was ./gitlab/config, ./gitlab/data and ./gitlab/logs) and tried to start gitlab/gitlab-ce:latest.
In the log files (docker logs gitlab) Gitlab told me the permissions have changed due to the copying. I searched the internet, found this on github.com and I had to run:
docker exec gitlab update-permissions
However, I still got error messages like Couldn't connect to redis. I took a look at the file system manually and found the permissions have not been set correctly. I had to run this command to fix it:
docker exec gitlab chown -R gitlab-redis:gitlab-redis /var/opt/gitlab/redis/ docker restart gitlab
