Gitlab Docker Updater

=> single command to update your gitlab docker container

Each execution of the program will update the container to the next minor version. To be safe, a backup will be made before upgrading gitlab version.

Required Setup

• gitlab running on linux server (tested with ubuntu 18.04)
• gitlab community edition
• docker-compose installed
• docker-compose.yml needs to fulfill the following criteria
  • container_name with the name of the gitlab container
  • image has to be an exact gitlab version (e.g. gitlab/gitlab-ce:12.9.0-ce.0 )
• jar has to be in the the same folder as docker-compose.yml
• java needs to be installed (tested with java 11)

Guide

• Download jar next to docker-compose.yml
• Run the jar with java -jar GitlabDockerUpdater-latest.jar

Steps, the program does in background

1. Get current version from docker-compose.yml
2. Check if there is a new version
3. Perform backup for current version
4. Set new version tag into docker-compose.yml
5. Pull new version image, restart docker container, display logs
6. After that point you can press strg+c at any time to stop the program
