How to access RabbitMQ web user interface

Issue: As a Domino administrator it is important to keep on top of the platform health. As RabbitMQ is a vital part of Domino you might want to have a visual overview of the service.  Since RabbitMQ is running as a cluster service it is not straight forward to access the user interface. This article describes an easy way to do this. 

Solution:  You will need several things in order to be able to access the web user interface. 
Firstly you will have to setup a tunnel to the service ip and port. This can be done via ssh tunnel to your control/bastion host and kubectl port-forward option. 

Example: 

#ssh <user@host> -t -L 15672:localhost:15672 'kubectl -n domino-platform port-forward svc/rabbitmq-ha 15672:15672'

Once this command is executed you will now have the tunnel setup and this will allow you to access RabbitMq inerface from your localhost. http://localhost:15672/

The second part is to acquire the credentials in order to view  RabbitMQ.  This part will be different for the different Domino versions. 

If you are running version of Domino >=4.1.x you will have to get the random password from the kubernetes secret. You can do so with the following command: 

#kubectl get secrets -n <Platform-Namespace> rabbitmq-ha -ojsonpath='{.data.rabbitmq-password}' | base64 -d ; echo

The output of the above command is the decoded password you can use in combination with the username as per the provided table .
