Arch Linux - Docker Node - Udating GitLab Container

I have revisited my GitLab container recently and noticed that it is asking for an update. Updating a GitLab docker container is relatively easy.

Let's follow GitLab's instructions.

1) Take a Backup

Let's get the GitLab container name.

CONTAINER ID   IMAGE                     COMMAND             CREATED        STATUS                  PORTS     NAMES
xxxxxxxxxxx   gitlab/gitlab-ee:latest   "/assets/wrapper"   3 months ago   Up 27 hours (healthy)             gitlab

To backup we need to execute the following command :

docker exec -t gitlab gitlab-backup create

Warning: Your gitlab.rb and gitlab-secrets.json files contain sensitive data 
and are not included in this backup. You will need these files to restore a backup.
Please back them up manually.
Backup task is done.

I do not need to worry about the configuration backups because my installation creates a backup daily and I will use the backups to restore.

2) Container Update

Before downloading the latest image we need to set the environment variable $GITLAB_HOME pointing to our installation home folder.

export GITLAB_HOME=/root/docker-projects/vlan.65-gitlab

Let's download the latest image.

docker-compose pull

Pulling gitlab ... done

We will stop the outdated container.

docker container stop gitlab

And finally update it but do not start yet.

docker-compose up -d --no-start

3) Restore Config Backup

When the container is recreated the configuration files will be recreated as well.

Restore the whole configuration backed up folder.

-rw------- 1 root root  19K Jan  7 17:56 gitlab-secrets.json
