Musicbrainz docker container

This repo contains everything needed to run a musicbrainz slave server with replication in a docker container.

First, thanks to Jeff Sturgis [email protected] with this repository : https://github.com/jsturgis/musicbrainz-docker

To make the install easier, you can user https://docs.docker.com/compose/

Installation

• docker-compose build

Update volumes setup

• vim docker-compose.yml

Start

• docker-compose up

Create Database

If this is a new instance and you need to create the database:

• sudo docker exec -ti musicbrainz bash
• cd /
• ./createdb.sh

Handling Schema Updates

When there is a schema change you will need to follow the directions posted by the musicbrainz team to update the schema. You can run bash in the running musicbrainz container like this:

sudo docker exec -ti musicbrainz bash

The usual process to update the schema is:

• Ensure you’ve replicated up to the most recent replication packet available with the old schema. (if you’re not sure, run ./admin/replication/LoadReplicationChanges and see what it tells you).
• In the running container Switch to the new code with git fetch origin followed by git checkout $NEW_SCHEMA_BRANCH and also update the Dockerfile to the new branch.
• In the running container run ./upgrade.sh
• Set DB_SCHEMA_SEQUENCE to $NEW_SCHEMA_NUM in this repo musicbrainz-dockerfile/DBDefs.pm
• On the host machine stop and remove the musicbrainz container and image
• On the host machine make sure the postgresql container is running
• In musicbrainz-dockerfile run sudo ./build.sh
• In musicbrainz-dockerfile run sudo ./run.sh

That’s it!
