    #                which is also propagated to `node` container (we can't generate password at
    #                image build time since it is not more secure than keeping the default
    #                password - because the generated password would be published with the image)
    #                But we may need to access RabbitMQ GUI management console for debugging
    #                purposes. Fix it to provide the access.
