socket.gaierror gaierror: [Errno -2] Name or service not known - pika rabbitMQ

I am trying to send a message from a python server hosted on localhost:5000 to a RabbitMQ server( using a docker image for RabbitMQ) , but I am getting the following error :

socket.gaierror gaierror: [Errno -2] Name or service not known

I am running the docker image for RabbitMQ using the command where 'rabbithost' is the hostname I am using:

sudo docker run -d --hostname rabbithost --name rabbitmq -p 15672:15672 -p 5672:5672 -p 5671:5671 rabbitmq:3-management

Here is the python code which is giving the error:

def send_to_queue(message):
    credentials = pika.PlainCredentials('guest', 'guest')
    parameters = pika.ConnectionParameters('rabbithost', 5672, '/', credentials)
    connection = pika.BlockingConnection(parameters)
    channel = connection.channel()
    channel.queue_declare(queue='hello')
    channel.basic_publish(exchange='', routing_key='hello',body=message)
    connection.close()
    return "Message Sent!  "

The error is at line :

connection = pika.BlockingConnection(parameters)

mainly because of the parameters argument. I am not able to find the exact solution for this error.

Where is the python code running? On localhost? If yes then you either need to change rabbithost to 127.0.0.1 or make a host entry in /etc/hosts for 127.0.0.1 rabbithost
