+====== Gitlab ======
+The current installation is under: http://gitlab.wialon-consulting.de:8080/
+===== Start =====
+A wrong method to start the Gitlab container:
+''sudo docker logs -f gitlab''
+The container will start. After that press Ctrl+C to exit the log.
+At the moment I don't know a better method to start the container => search for it.
+Note (05.05.2023):
+''sudo docker start gitlab''
+worked too... I don't know why it was not possible previously. Maybe something goes wrong, but I didn't seen it?
+===== Backup =====
+I made backup with the help of this document: https://docs.gitlab.com/ee/raketasks/backup_restore.html
+The command was: ''sudo docker exec -t gitlab gitlab-rake gitlab:backup:create''
+Also I've copied the ''/dockerdata/gitlab/config'' directory to ''~/gitlab.bak/config''.
+===== Restore =====
+I've used the following document: https://docs.gitlab.com/ee/raketasks/backup_restore.html#restore-gitlab
+So:
+<code bash>
+# Stop the processes that are connected to the database
+sudo docker exec -it gitlab gitlab-ctl stop puma
+sudo docker exec -it gitlab gitlab-ctl stop sidekiq
+# Verify that the processes are all down before continuing
+sudo docker exec -it gitlab gitlab-ctl status
+# Run the restore. NOTE: "_gitlab_backup.tar" is omitted from the name
+sudo docker exec -it gitlab gitlab-backup restore BACKUP=1637386323_2021_11_20_14.4.2
+# Restart the GitLab container
+sudo docker restart gitlab
+# Check GitLab
+sudo docker exec -it gitlab gitlab-rake gitlab:check SANITIZE=true
+</code>
+===== Upgrade =====
+I made upgrade with the following document: https://docs.gitlab.com/ee/install/docker.html#update-gitlab-using-docker-engine
+. I made a backup (see above)
+. I stopped the running container:
+<code>
+sudo docker stop gitlab
+</code>
+. I removed the container:
+<code>
+sudo docker rm gitlab
+</code>
+. I pulled the new image:
+<code>
+sudo docker pull gitlab/gitlab-ce:latest
+</code>
+. Then I created the new container with the following command:
+<code>
+sudo docker run --detach \
+--hostname gitlab.wialon-consulting.de \
+--publish 8443:443 --publish 8080:80 --publish 1022:22 \
+--name gitlab \
+--restart always \
+--volume $GITLAB_HOME/config:/etc/gitlab \
+--volume $GITLAB_HOME/logs:/var/log/gitlab \
+--volume $GITLAB_HOME/data:/var/opt/gitlab \
+gitlab/gitlab-ce:latest
+</code>
+Unfortunately I couldn't upgrade directly to the latest version, so it was necessary to upgrade major versions:
+<code bash>
+sudo docker pull gitlab/gitlab-ce:12.0.0-ce.0
+# then stop container, remove container, create new container, then pull new version ...
+sudo docker pull gitlab/gitlab-ce:13.0.0-ce.0
+# ... then run it again
+</code>
+===== Installed versions =====
+  * Installed versions
+    * **+** 11.11.3-ce.0
+    * **+** 12.0.0-ce.0
+    * **-** ...
+    * **+** 14.0.0-ce.0
+    * **+** 14.0.5-ce.0
+      * ''sudo docker pull gitlab/gitlab-ce:14.0.5-ce.0''
+      * **Important for this version** (I had problems with this upgrade):
+        * The batched background migrations should be completed before upgrade to the next version. See [[https://docs.gitlab.com/ee/update/#1400|Upgrade instructions for 14.0.0]] and [[https://docs.gitlab.com/ee/update/#check-the-status-of-batched-background-migrations|Check the status of batched background migrations]]
+    * **+** 14.0.12-ce.0
+      * ''sudo docker pull gitlab/gitlab-ce:14.0.12-ce.0''
+    * **-** 14.1.0-ce.0
+      * ''sudo docker pull gitlab/gitlab-ce:14.1.0-ce.0''
+      * The upgrade from 14.0.12 to 14.1.0 did not worked! I rolled back, but it did not worked too. What worked after roll back is the upgrade to 14.1.1. See https://gitlab.com/gitlab-org/omnibus-gitlab/-/issues/6352#note_659967231
+    * **+** 14.1.1-ce.0
+      * ''sudo docker pull gitlab/gitlab-ce:14.1.1-ce.0''
+    * **+** 14.2.1-ce.0
+      * ''sudo docker pull gitlab/gitlab-ce:14.2.1-ce.0''
+    * **-** 14.3.0-ce.0
+      * ''sudo docker pull gitlab/gitlab-ce:14.3.0-ce.0''
+      * This upgrade (14.2.1 -> 14.3.0) did not work, so I had to take rollback and upgrade to 14.3.1 after that. So: 14.2.1 -> 14.3.0 -> 14.2.1 -> 14.3.1.
+    * **+** 14.3.1-ce.0
+      * ''sudo docker pull gitlab/gitlab-ce:14.3.1-ce.0''
+    * **+** 14.4.1-ce.0
+      * ''sudo docker pull gitlab/gitlab-ce:14.4.1-ce.0''
+    * **+** 14.4.2-ce.0
+      * ''sudo docker pull gitlab/gitlab-ce:14.4.2-ce.0''
+===== Misc =====
+==== Big log file ====
+Gitlab creates a big log file in the current container:
+  * at the moment:
+    * ''/var/lib/docker/containers/992bd1257242f4e8ac5288959bf5e0a822afd7813e470b4bc48f614e22b931b7/992bd1257242f4e8ac5288959bf5e0a822afd7813e470b4bc48f614e22b931b7-json.log''
+So it is necessary to remove this file regularly (possible only as root):
+<code bash>
+sudo -s
+cd /var/lib/docker/containers/992bd1257242f4e8ac5288959bf5e0a822afd7813e470b4bc48f614e22b931b7
+rm 992bd1257242f4e8ac5288959bf5e0a822afd7813e470b4bc48f614e22b931b7-json.log
+</code>
+Other command which can be useful is **du** (disk usage):
+<code bash>
+# disk usage of all directories and files in current directory
+du -sh ./*
+# disk usage of a specific directory
+du -sh directory_name
+</code>
+==== Gitlab configuration ====
+The gitlab configuration is in file: ''/dockerdata/gitlab/config/gitlab.rb''
+At the moment I've changed only prometheus configuration:
+<code>
+prometheus['enable'] = false
+</code>
+Also interesting info about cleaning of prometheus data: https://forum.gitlab.com/t/clear-up-postges-prometheus-data/38216
