Gerrit slave init container image

Kubernetes init container for initializing gerrit. The python script running in the container makes sure, that the database is initialized (currently supported: H2 and MySQL) and initializes Gerrit including the installation of configured core plugins.

Start

• start the container via start script /var/tools/gerrit_init.py

The gerrit_init.py-script

• reads configuration from gerrit.config (via gerrit_config_parser.py)
• waits for the database to start (via validate_db.py)
• initializes Gerrit

How to install/update python packages in container

• Python 3.6 is required
• Install pipenv
• Navigate to ./container-images/gerrit-init/tools
• Run pipenv install <package>

This will update the Pipfile and Pipfile.lock, which will be copied into the container image, when the container image is built.
