Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

Highlights

docker run to run a new container
docker ps to see running and stopped containers
docker images to see info about images
Intsalling docker gives you the client and Daemon, client makes API call to Daemon, Daemon implements the Docker Remote API, docker run starts a new container
Docker Hub is a docker image registry, a place where to can store images right a place where we want to use containers

RabbitMQ

if you launched rabbitmq by using somthing like:

docker run -d --name some-rabbit -p 4369:4369 -p 5671:5671 -p 5672:5672 -p 15672:15672 rabbitmq

then you can enable its management plugins while that container runs using the following command:

docker container exec -it some-rabbit rabbitmq-plugins enable rabbitmq_management

Best: docker run -it --rm --name rabbitmq -p 5672:5672 -p 15672:15672 rabbitmq:3.10-management

and the management GUI is running on http://localhost:15672 For management GUI
