Correct path for rabbitmq Docker container in Windows

Question

I have a RabbitMQ Docker container in a docker-compose.yml file.

  rabbit:
    image: rabbitmq:3-management
    ports:
      - "15672:15672"
      - "5672:5672"
      - "61613:61613"
      - "15674:15674"
    volumes:
      - ./enabled_plugins:/etc/rabbitmq/enabled_plugins
    labels:
      - "traefik.enable=true"
      - "traefik.docker.network=default"
      - "traefik.ws.port=15674"
      - "traefik.ws.frontend.rule=PathPrefixStrip:/stomp/"
      - "traefik.web.port=15672"
      - "traefik.web.frontend.rule=PathPrefixStrip:/rabbit/"

The problem is that when I do docker-compose up -d, there is an error.

$ docker-compose up -d

There seems to be no problems in Linux environment, only on Windows. I assume the path for enabled_plugins file is incorrect. I've tried changing the mapping to something like

• ./enabled_plugins:/c/rabbitmq

and the container seems to start, but the server is not responding, so I guess the plugins from the enabled_plugins file were not properly installed.

Whole docker-compose.yml file can be seen here: https://github.com/maxmeister/deploji-server/blob/master/docker-compose.yml

Any advice on how could I make it run okay on my Windows machine? Thanks in advance.

I would suggest following the docs : There are several options if use short syntax:

SHORT SYNTAX Optionally specify a path on the host machine (HOST:CONTAINER), or an access mode (HOST:CONTAINER:ro).

You can mount a relative path on the host, that expands relative to the directory of the Compose configuration file being used. Relative paths should always begin with. or...

volumes:
  # Just specify a path and let the Engine create a volume
  - /var/lib/mysql

  # Specify an absolute path mapping
  - /opt/data:/var/lib/mysql

  # Path on the host, relative to the Compose file
  - ./cache:/tmp/cache

  # User-relative path
  - ~/configs:/etc/configs/:ro

  # Named volume
  - datavolume:/var/lib/mysql
