RabbitMQ Server Pod Crash Loop BackOff on Azure AKS Cluster

[AlbertoBettaACN]

When trying to install Rabbit MQ Server on Azure Kubernetes Cluster with Cluster Operator the Pod of the RabbitMQ Server gets stuck on Crash BackOff.

This is the yaml used:

apiVersion: rabbitmq.com/v1beta1
kind: RabbitmqCluster
metadata:
name: hello-world
namespace: rabbitmq-system

It creates the statuful set but the Pod triggered by the Statefull Set gives this error ( by running kubectl logs hello-world-server-0 -n rabbitmq-system)

`WARNING: 'docker-entrypoint.sh' generated/modified the RabbitMQ configuration file, which will no longer happen in 3.9 and later! (docker-library/rabbitmq#424)

Generated end result, for reference:

loopback_users.guest = false
total_memory_available_override_value = 2147483648
listeners.tcp.default = 5672
management.tcp.port = 15672

Don't use the rabbitmq-system as your namespace. Instead use default or another namespace you prefer.
