DEFAULT_VHOST=/ DEFAULT_USER= DEFAULT_PASS=
In docker compose file, instead of an environment section put a volumes section and mounted the rabbitmq.conf file to proper path (depending on OS, follow here). For linux container it will be like:
rabbit: image: "rabbitmq:3-management" hostname: "rabbit" volumes: - "./rabbitmq.conf:/etc/rabbitmq/rabbitmq.conf" ports: - "15672:15672" - "5672:5672" labels: NAME: "rabbitmq" networks: - postgres
Option 2: For
If you are using
Dockerfile, type your config in this same folder and add this line to your
COPY ./rabbitmq.conf /etc/rabbitmq/rabbitmq.conf
