MusicBrainz slave server with search and replication

Hello,

I’m testing MusicBrainz slave server with search and replication on a vm as described at https://github.com/metabrainz/musicbrainz-docker/tree/mbvm-38-dev (README.md)

On the step:
docker-compose exec indexer python -m sir amqp_setup
2020-04-15 18:54:01,619: Connecting to RabbitMQ

Seems rabbitmq is not running. Already tried to run it manually but got this error anyway.

Some lights?

Thanks

Hi,

Docker Compose mq service running RabbitMQ must be up to set up AMQP.

Make sure all services are up before enabling live indexing:

docker-compose up -d
docker-compose ps

Hello @yvanzo

mq service is running:
musicbrainz-docker_mq_1 /docker-entrypoint-wrapper.sh Up 15671/tcp, 15672/tcp, 25672/tcp, 4369/tcp, 5671/tcp, 5672/tcp

but all those ports are closed,

thanks

How do you test these ports? They are not published to the host by default. They should be accessible from other services of this compose project only.

Try to refresh the image and the container for the service mq:

docker-compose rm --stop mq
docker-compose build --no-cache --pull mq
docker-compose up -d

Otherwise the bug might come from your Docker host. Here are similar issues:

Hi @yvanzo, I thought ports would be open for the host.
The refresh of the image you suggested didn’t work.
I switched from docker engine I was running from 19.03.8 to 18.09.9 and was finally able to successfully run
docker-compose exec indexer python -m sir amqp_setup

So it seems it was a problem with new docker version.
Thanks!

I’m glad your problem is resolved, but there was likely another cause as I’m using Docker 19.03.8 too.
