Update

Pre-checks before update

sudo docker exec -it gitlab gitlab-rake gitlab:check sudo docker exec -it gitlab gitlab-rake gitlab:doctor:secrets

Checks the update path

In functions of your update, checks the path
https://gitlab-com.gitlab.io/support/toolbox/upgrade-path/ 14.10.5 -> 15.0.5 -> 15.4.6 -> 15.8.0

On your Workstation:

podman pull gitlab/gitlab-ce:15.0.5-ce.0
podman save gitlab/gitlab-ce:15.0.5-ce.0 > sources/gitlab-ce:15.0.5-ce.0.tar

Export the tar to the target host

docker load < /tmp/gitlab-ce:15.0.5-ce.0.tar
docker stop gitlab
docker rm gitlab
docker run -d -p 5050:5050 -p 2289:22 -p 443:443 --restart=always \
-v /data/gitlab/config:/etc/gitlab \
-v /data/gitlab/logs:/var/log/gitlab \
-v /data/gitlab/data:/var/opt/gitlab \
-v /data/gitlab/cert:/etc/gitlab/ssl \
-v /data/gitlab/config/trusted-certs:/usr/local/share/ca-certificates \
--name gitlab gitlab/gitlab-ce:15.0.5-ce.0
