…ANG_COOKIE vars Those environment variables are unset by default. The default values are set in the `rabbit` application environment and can be configured in the configuration file. However, the environment variables will take precedence over them respectively if they are set.
They are the equivalent of the `default_{user,pass,vhost}` configuration
settings. Each set environment variable will take precedence over its
configuration file counterpart.
Fixes docker-library/rabbitmq#508.
It is the equivalent of the content of the Erlang cookie file. Note this variable IS the cookie value, NOT the path to a cookie file. If it is set, it will take precedence over the content of the Erlang cookie file. Fixes docker-library/rabbitmq#508.

It works as expected: RABBITMQ_DEFAULT_VHOST=pr-3299-vhost RABBITMQ_DEFAULT_USER=pr-3299 RABBITMQ_DEFAULT_PASS=pr-3299 gmake run-brokerrabbitmqctl list_users
# => Listing users ...
# => user tags
# => pr-3299 [administrator]
rabbitmqctl list_vhosts
# => Listing vhosts ...
# => name
# => pr-3299-vhost |
RABBITMQ_ERLANG_COOKIE=abcd gmake run-brokerMakes CLI authentication fail unless |
as it can be really difficult to troubleshoot such cookie changes

Historically, the Docker image allowed the user to override the default user/password and vhost as well as the Erlang cookie from environment variables among other things. After some discussion in docker-library/rabbitmq#506 (comment), support for environment variables specific to the Docker image was removed in docker-library/rabbitmq#467.
Several users were impacted by this removal (see docker-library/rabbitmq#508). After some more discussion, it was decided to re-introduce some variables directly into RabbitMQ itself. The following variables are added by this patch:
$RABBITMQ_DEFAULT_USER(overridesdefault_user)$RABBITMQ_DEFAULT_PASS(overridesdefault_pass)$RABBITMQ_DEFAULT_VHOST(overridesdefault_vhost)$RABBITMQ_ERLANG_COOKIE(overrides the Erlang cookie file content)Fixes docker-library/rabbitmq#508
