I've used docker to start my rabbitmqserver. How can I use rabbitmqctl to connect to the rabbitmqserver in the docker container?
Port 5672 has been exposed and map to the 5672 port of my host. But I still get the following error:
Status of node rabbit@m2 ...
Error: unable to connect to node rabbit@m2: nodedown

Open a terminal, navigate to your rabbitmq-go folder and run docker-compose up . This command will pull the rabbitmq:3-management-alpine image, create the container rabbitmq and start the service and webUI. You should see something like this: Once you see this, open your browser and head over to http://localhost:15672.
If you open your Docker engine, you will see the RbbitMQ container set and running. If you open http://localhost:15672/ on a browser, you will be able to access the management Ui, and now you can log in using the docker-compose set username and password. And now you can see the RabbitMQ instance is up and running.
Install Docker on your SSH host. You do not need to install Docker locally. Follow the quick start for the Remote - SSH extension to connect to a host and open a folder there. Use the Remote-Containers: Reopen in Container command from the Command Palette (F1, Ctrl+Shift+P).
Use docker attach to attach your terminal's standard input, output, and error (or any combination of the three) to a running container using the container's ID or name. This allows you to view its ongoing output or to control it interactively, as though the commands were running directly in your terminal.
Assuming your container is called rabbitmq and is running:
docker exec rabbitmq rabbitmqctl start_app
rabbitmqctl uses Erlang Distributed Protocol (EDP) to communicate with RabbitMQ. Port 5672 provides AMQP protocol. You can investigate EDP port that your RabbitMQ instance uses:
$ netstat -uptan | grep beam
tcp 0 0 0.0.0.0:55950 0.0.0.0:* LISTEN 31446/beam.smp
tcp 0 0 0.0.0.0:15672 0.0.0.0:* LISTEN 31446/beam.smp
tcp 0 0 0.0.0.0:55672 0.0.0.0:* LISTEN 31446/beam.smp
tcp 0 0 127.0.0.1:55096 127.0.0.1:4369 ESTABLISHED 31446/beam.smp
tcp6 0 0 :::5672 :::* LISTEN 31446/beam.smp
It means that RabbitMQ:
To make rabbitmqctl able to connect to RabbitMQ you also have to forward port 55950 and allow RabbitMQ instance connect to 127.0.0.1:4369.
It is possible that RabbitMQ EDP port is dinamic, so to make it static you can try to use ERL_EPMD_PORT variable of Erlang environment variables or use inet_dist_listen_min and inet_dist_listen_max of Erlang Kernel configuration options and apply it with RabbitMQ environment variable - export RABBITMQ_CONFIG_FILE="/path/to/my_rabbitmq.conf
my_rabbitmq.conf
[{kernel,[{inet_dist_listen_min, 55950},{inet_dist_listen_min, 55950}]}].
Or you can use RabbitMQ Management Plugin. It is more functional and simple to setup.
