LidarrAPI.Metadata

This hosts the custom metadata API and resources Lidarr relies on.

Installation

The metadata server may be installed with pip install . in the root directory or python setup.py install. A development install that is linked to the most recent file versions may be installed with pip install -e . or python setup.py develop.

Running

The metadata API server may be run by executing the server.py file or by the command lidarr-metadata-server that is installed with the installation instructions above.

Docker services

The metadata server requires access to a musicbrainz postgresql database and solr search server.

To initialize a fresh VM, you can use:

#! /bin/bash
curl -fsSL https://get.docker.com | sh
curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
apt install -y --no-install-recommends emacs-nox git

To initialize the musicbrainz db run (do not set brainzcode at this point):

docker-compose up -d db
docker-compose run --rm musicbrainz /usr/local/bin/createdb.sh -fetch

To set up the search index triggers, run:

docker-compose up -d indexer musicbrainz
docker-compose exec indexer python -m sir amqp_setup
admin/create-amqp-extension
admin/setup-amqp-triggers install

To set up the search indices, run:

docker-compose run --rm musicbrainz fetch-dump.sh search
docker-compose run --rm search load-search-indexes.sh --force

The database / search indices are now in line with the latest musicbrainz weekly dump. To enable replication, set the brainzcode and run:

docker-compose up -d

And wait for the database / indices to catch up with the latest hourly replication. This could take a long time.

Next create the extra indices lidarr needs in:

lidarrmetadata/sql/CreateIndices.sql

Then you need to set up the lidarr cache:

docker-compose up -d cache-db
docker-compose run --rm crawler

• docker-compose.yml defines the base services required - the musicbrainz database, server, solr and supporting services.
• docker-compose.dev.yml exposes ports for the supporting services in docker-compose.yml to allow running the lidarr metadata service on the host.
• docker-compose.prod.yml runs the lidarr metadata service in docker in addition to the supporting services. Supporting services are not exposed.
