musicbrainz slave server with search and replication

This repo contains everything needed to run a musicbrainz slave server with search and replication in docker. You will need a little over 20 gigs of free space to run this with replication.

Versions

• Current MB Branch: v-2016-05-23-schema-change-v2
• Current DB_SCHEMA_SEQUENCE: 23
• Postgres Version: 9.5

Configuration

• Set the path where you want to store the downloaded data dumps in docker-compose.yml.
• If you already have data dumps in this path they can be loaded instead of downloading new dumps, see Create Database.

Installation

Install and Start

• Make sure you have installed docker and docker-compose then:
• git clone this-repo
• cd this-repo
• sudo docker-compose up -d
• Set the token you got from musicbrainz (instructions for generating a token are here).
• sudo docker exec musicbrainzdocker_musicbrainz_1 /set-token.sh <replication token>

Create database

Create the database, download the latest dumps and populate the database

• sudo docker-compose run --rm musicbrainz /createdb.sh -fetch

Create the database, and populate the database with existing dumps

• sudo docker-compose run --rm musicbrainz /createdb.sh

Build search indexes

In order to use the search functions of the web site/API you will need to build search indexes.

• sudo docker-compose run --rm indexer /home/search/index.sh

If you need to recreate the database

you will need to enter the postgres password that you set in postgres.env.

• sudo docker-compose run --rm musicbrainz /recreatedb.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.

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 sudo docker exec musicbrainzdocker_musicbrainz_1 ./admin/replication/LoadReplicationChanges).
• Switch to the new code with:
• Run bash in the container: sudo docker exec -ti musicbrainzdocker_musicbrainz_1 bash.
• Checkout the new branch: git fetch origin && git checkout NEW_SCHEMA_BRANCH.
• Run the upgrade script: ./upgrade.sh.
• Exit bash exit.
• Set DB_SCHEMA_SEQUENCE to the NEW_SCHEMA_NUM in the DBDefs.pm file
• sudo docker-compose stop musicbrainz then sudo docker-compose build musicbrainz then sudo docker-compose up -d --no-deps musicbrainz

If anything doesn't work create an issue and submit a pull request.
