GitLab releases updates to its Enterprise Edition software very regularly. A major upgrade is always released the 22nd of every month.
To perform an upgrade,
Schedule a maintenance period
Perform a backup of data either via a Ceph snapshot or gitlab-rake
As root on
gitlab-rake gitlab:backup:create STRATEGY=copy
to backup all repositories to /var/opt/gitlab/backups
As root on a Ceph monitor, run the following to perform a snapshot of the Ceph image
rbd snap create virtual-machines/[email protected]<SNAPSHOT NAME>
Run the following to upgrade GitLab
apt update && apt upgrade -y
The above upgrade will take time to perform. When the upgrade finishes, it should give you a success message. After the upgrade successfully completes, it will take a few minutes for all workers to start up so in that time frame you may see a 502 when accessing the site.
