**Purpose**: Docker container running Ubuntu Minimal 22.04 that automates much of the script mentioned in the [Git Repo Updater](https://docs.cyberstrawberry.net/General%20Scripts/Bash/Git%20Repo%20Updater) document. It offers the additional benefits of checking for updates every 5 seconds instead of every 60 seconds. It also accepts environment variables to provide credentials and notification settings.
