The management interface does not display properly

Direct installation is no problem

There's a rabbitmq:management tag with the management plugin installed https://github.com/docker-library/docs/tree/master/rabbitmq#management-plugin

The warning is because the image disables management metrics in the default image because prometheus metrics are enabled (#422):

rabbitmq/Dockerfile-ubuntu.template

Lines 251 to 254 in 66ddebb

	# Enable Prometheus-style metrics by default (https://github.com/docker-library/rabbitmq/issues/419)
	RUN set -eux; \
	rabbitmq-plugins enable --offline rabbitmq_prometheus; \
	echo 'management_agent.disable_metrics_collector = true' > /etc/rabbitmq/conf.d/management_agent.disable_metrics_collector.conf

But it is re-enabled in the management image:

rabbitmq/Dockerfile-management.template

Lines 5 to 6 in 66ddebb

	# make sure the metrics collector is re-enabled (disabled in the base image for Prometheus-style metrics by default)
	RUN rm -f /etc/rabbitmq/conf.d/management_agent.disable_metrics_collector.conf
