@djsisson why is it not enough if we add a persitant volume:

services:
  rabbitmq:
    image: rabbitmq:3-management
    environment:
      - SERVICE_FQDN_RABBITMQ_15672
      - RABBITMQ_DEFAULT_USER=$SERVICE_USER_RABBITMQ
      - RABBITMQ_DEFAULT_PASS=$SERVICE_PASSWORD_RABBITMQ
      - PORT=${PORT:-5672}
    ports:
      - ${PORT}:5672
    healthcheck:
      test: rabbitmq-diagnostics -q ping
      interval: 5s
      timeout: 30s
      retries: 10
    volumes:
      - rabbitmq-data:/var/lib/rabbitmq/

see linked gh issue on rabbitmq

'if hostname is not provided, it creates a random hostname each time service is restarted.'
which means although the volume stays the same, all previous data in there is not used due to using a new hostname

ah i see, maybe youre right, i didnt see it wasnt global storage :)

But this is just rabbitmq issue this does not happen with docker in general, right or am I wrong?

[djsisson]

this is just a rabbitmq issue

if you run without host and check logs/volumes you get something like this

/var/lib/rabbitmq/mnesia/rabbit@ee90f8d1363e

restart

/var/lib/rabbitmq/mnesia/rabbit@32b510b78640

setting a hostname stops this from happening

Alright looks good.
Thank you for the PR 💜.
