How to connect to server on Docker from host machine?

Question

Ok, I am pretty new to Docker world. So this might be a very basic question.

I have a container running in Docker, which is running RabbitMQ. Let's say the name of this container is "Rabbit-container".

RabbitMQ container was started with this command:

docker run -d -t -i --name rmq -p 5672:5672 rabbitmq:3-management 

Python script command with 2 args:

python ~/Documents/myscripts/migrate_data.py amqp://rabbit:5672/ ~/Documents/queue/

Now, I am running a Python script from my host machine, which is creating some messages. I want to send these messages to my "Rabbit-container". Hence I want to connect to this container from my host machine (Mac OSX).

Is this even possible? If yes, how?

Please let me know if more details are needed.

Answer 1

So, I solved it by simply mapping the RMQ listening port to host OS:

docker run -d -t -i --name rmq -p 15672:15672 -p 5672:5672 rabbitmq:3-management

I previously had only -p 15672:15672 in my command. This is mapping the Admin UI from Docker container to my host OS. I added -p 5672:5672, which mapped RabbitMQ listening port from Docker container to host OS.
