How to open rabbitmq in browser using docker container?

You are using the wrong image which doesn't have the rabbitmq_management plugin enabled. Change rabbitmq:latest to rabbitmq:management.

On dockerhub they are using the command:

docker run -d --hostname my-rabbit --name some-rabbit rabbitmq:3-management

If you want to go to the UI on localhost:15672 make sure to expose the port by adding -p 15672:15672 to the above command.

The management image is just the rabbitmq latest image with the management plugin enabled. Here is the dockerfile for rabbitmq:management

FROM rabbitmq

RUN rabbitmq-plugins enable --offline rabbitmq_management

EXPOSE 15671 15672

First off, you need the management image (eg. rabbitmq:3-management) to access it through the browser. If your docker is running locally, then you should be able to access it by navigating to http://localhost:{port} or http://127.0.0.1:{port} (15672 by default).

Here is an example of a simple docker-compose.yml:

version: "3"
services:
 rabbitmq:
    image: "rabbitmq:3-management"
    ports:
      - "5672:5672"
      - "15672:15672"
    volumes:
      - 'rabbitmq_data:/data'

volumes:
  rabbitmq_data:

After starting the container, Rabbitmq is now accessible at http://127.0.0.1:15672. The default username and password should be guest:guest. More details here.

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.
