Creating a new queue in RabbitMQ through docker-compose

Question

Just sharing how I did to create automatically queues when RabbitMq starts:

version: "3.2"
services:
  rabbitmq:
    image: rabbitmq:3-management-alpine
    environment:
      RABBITMQ_DEFAULT_USER: guest
      RABBITMQ_DEFAULT_PASS: guest
    container_name: rabbitmq
    ports:
      - 5672:5672
      - 15672:15672
    volumes:
      - ./queues/rabbitmq/init.sh:/init.sh
    restart: "no"
    entrypoint: [ "bash", "-c", "sleep 3 && ./init.sh"]
    networks:
      abinbev_net:
        ipv4_address: 173.101.101.101

networks:
  abinbev_net:
    driver: bridge
    ipam:
      driver: default
      config:
        - subnet: 173.101.101.0/24

And my init.sh

#!/bin/bash
echo "Generating a new queue through commandline"
#!/bin/sh

# Create Rabbitmq user
( sleep 5 ; \
rabbitmqctl add_user $RABBITMQ_USER $RABBITMQ_PASSWORD 2>/dev/null ; \
rabbitmqctl set_user_tags $RABBITMQ_USER administrator ; \
rabbitmqctl set_permissions -p / $RABBITMQ_USER  ".*" ".*" ".*" ; \
rabbitmqadmin -u guest -p guest -V / declare queue name=otc-finance-reference-receive-queue ; \
echo "*** User '$RABBITMQ_USER' with password '$RABBITMQ_PASSWORD' completed. ***" ; \
echo "*** Log in the WebUI at port 15672 (example: http:/localhost:15672) ***") &

# $@ is used to pass arguments to the rabbitmq-server command.
# For example if you use it like this: docker run -d rabbitmq arg1 arg2,
# it will be as you run in the container rabbitmq-server arg1 arg2
rabbitmq-server $@

So it's working fine but I'd like to know if you have another shape to make that. Thanks, Raphael
