Can't connect to RabbitMQ via docker container

Question

I can't connect to RabbitMQ via docker file.

After using docker run I'm getting

pika.exceptions.AMQPConnectionError

That's line 14 and 15

connection = pika.BlockingConnection(pika.ConnectionParameters(host=cfg.RABBIT_HOST))
channel = connection.channel()

and config file

RABBIT_HOST= 'localhost'
QUEUE_TOPIC = 'topic_name'

connecting to localhost:15672 works and it's showing me rabbitmq login window, but still doesn't work with python connection

Answer 1

Ok, that was my fault. Adding the credentials fixed the problem.
