I'm trying to follow this guide to set up a MySQL instance to connect to. The Kubernetes cluster is run on Minikube.

From the guide, I have this to set up my persistent volume:

apiVersion: v1
kind: PersistentVolume
metadata:
  name: mysql-pv-volume
  labels:
    type: local
spec:
  storageClassName: manual
  capacity:
    storage: 1Gi
  accessModes:
    - ReadWriteOnce
  hostPath:
    path: "/mnt/data"
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: mysql-pv-claim
spec:
  storageClassName: manual
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 1Gi

I ran kubectl describe pods/mysql-c85f7f79c-kqjgp and got this:

When I get the logs via kubectl logs pods/mysql-c85f7f79c-kqjgp, I only see this:

2020-01-30 03:50:47+00:00 [Note] [Entrypoint]: Entrypoint script for MySQL Server 5.6.47-1debian9 started.
2020-01-30 03:50:47+00:00 [Note] [Entrypoint]: Switching to dedicated user 'mysql'
2020-01-30 03:50:47+00:00 [Note] [Entrypoint]: Entrypoint script for MySQL Server 5.6.47-1debian9 started.

Is there a better way to debug? Why are the logs empty?
