RabbitMQ Cluster Kubernetes Operator on minikube
W-K-S
I'm trying to set up RabbitMQ on Minikube using the RabbitMQ Cluster Operator:
When I try to attach a persistent volume, I get the following error:
$ kubectl logs -f rabbitmq-rabbitmq-server-0 Configuring logger redirection 20:04:40.081 [warning] Failed to write PID file "/var/lib/rabbitmq/mnesia/rab...@rabbitmq-rabbitmq-server-0.rabbitmq-rabbitmq-headless.default.pid": permission denied 20:04:40.264 [error] Failed to create Ra data directory at '/var/lib/rabbitmq/mnesia/rab...@rabbitmq-rabbitmq-server-0.rabbitmq-rabbitmq-headless.default/quorum/rab...@rabbitmq-rabbitmq-server-0.rabbitmq-rabbitmq-headless.default', file system operation error: enoent 20:04:40.265 [error] Supervisor ra_sup had child ra_system_sup started with ra_system_sup:start_link() at undefined exit with reason {error,"Ra could not create its data directory.

See the log for details."} Crash dump is being written to: erl_crash.dump...The issue is that RabbitMQ is not able to set up its data files in the data directory /var/lib/rabbitmq/mnesia due to a lack of permission.
My initial guess was that I needed to specify the data directory as a volumeMount, but that doesn't seem to be configurable according to the documentation.
I tried to find other resources online with the same problem but none of them were using the RabbitMQ Cluster Operator. I plan on following that route if I'm not able to find a solution but I really would like to solve this issue somehow.
Does anyone have any ideas?
The setup that I have is as follows:
apiVersion: rabbitmq.com/v1beta1
kind: RabbitmqCluster
metadata:
name: rabbitmq
spec:
replicas: 1
service:
type: NodePort
persistence:
storageClassName: local-storage
storage: 20Gi
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: rabbitmq-pvc
spec:
storageClassName: local-storage
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 20Gi
---
apiVersion: v1
kind: PersistentVolume
metadata:
name: rabbitmq-pv
spec:
storageClassName: local-storage
accessModes:
- ReadWriteOnce
capacity:
storage: 20Gi
hostPath:
path: /mnt/app/rabbitmq
type: DirectoryOrCreate
