Gerrit slave init container image

Kubernetes init container for initializing a gerrit slave. Currently also used to initialize gerrit master using a different Entrypoint, will be cleaned up in a future change.

Content

• gerrit-slave image

Setup and configuration

• install mysql-client
• copy tool scripts

Start

• verify filesystem permissions
• start the container via start script /var/tools/start (definition of Entrypoint is inherited from gerrit-base image)

The start script

• reads database configuration from gerrit.config
• waits for the database to start
• waits for All-Projects.git and All-Users.git to arrive via replication via apache-git-http-backend from Gerrit master
• waits for MySQL slave database schema to arrive via database replication from Gerrit slave
