RabbitMq on Docker connection fail

Question

Im learning basics of RabbitMQ, installed it on a container. When inspecting the container it seems ok .

PS C:\Users\jvidin> docker port rabbitmq
25672/tcp -> 0.0.0.0:32776
4369/tcp -> 0.0.0.0:32779
5671/tcp -> 0.0.0.0:32778
5672/tcp -> 0.0.0.0:32777
PS C:\Users\jvidin> docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                                                                                                 NAMES

But than when trying to connect via Pika Python lib as below it fails with message below

pika.exceptions.ConnectionClosed: Connection to 127.0.0.1:5672 failed: timeout

Code

import pika
connection = pika.BlockingConnection(pika.ConnectionParameters(host='localhost'))
channel = connection.channel()

channel.queue_declare(queue='hello')
channel.basic_publish(exchange='', routing_key='hello', body='Hello World!')
print(" [x] Sent 'Hello World!'")
connection.close()

RESOLUTION BELOW CORRECT CONNECTION INFO

connection = pika.BlockingConnection(pika.ConnectionParameters(host='localhost', port=32777))

Answer 1

You need to configure your python client to use localhost:32777.

Just check the output of docker port rabbitmq. It shows that container port 5672 is mapped to port 32777 on your docker host.
