This was probably asked already, but so far I can\'t find any detailed explanation at all, and the existing documentation seems as if it was written for some kind on psychic
Better to expose all three ports (5672, 5673, 15672).
docker run -d --name some-rabbit -p 5672:5672 -p 5673:5673 -p 15672:15672 rabbitmq:3-management
Then you may browse, http://localhost:15672/ with the credentials "guest" for both the username and the password.
