Missing Persistent Volume and Storage Class Configuration in MySQL-WordPress Tutorial #46814

Open lsdeva opened 3 months ago

lsdeva commented 3 months ago

The current MySQL-WordPress tutorial does not include the necessary steps for creating Persistent Volumes (PVs) and defining the storage class. This can lead to Persistent Volume Claims (PVCs) remaining in a Pending state due to the absence of available PVs with the required storage class.

Create Persistent Volumes (PVs) with the Standard Storage Class:

apiVersion: v1
kind: PersistentVolume
metadata:
  name: mysql-pv
spec:
  capacity:
    storage: 20Gi
  accessModes:
    - ReadWriteOnce
  persistentVolumeReclaimPolicy: Retain
  storageClassName: standard
  hostPath:
    path: /mnt/data/mysql
---
apiVersion: v1
kind: PersistentVolume
metadata:
  name: wordpress-pv
spec:
  capacity:
    storage: 20Gi
  accessModes:
    - ReadWriteOnce
  persistentVolumeReclaimPolicy: Retain
  storageClassName: standard
  hostPath:
    path: /mnt/data/wordpress

Define Persistent Volume Claims (PVCs) with Matching Storage Class:

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: mysql-pv-claim
  labels:
    app: wordpress
spec:
  accessModes:
    - ReadWriteOnce
  **storageClassName: standard**
  resources:
    requests:
      storage: 20Gi
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: wp-pv-claim
  labels:
    app: wordpress
spec:
  accessModes:
    - ReadWriteOnce
  **storageClassName: standard**
  resources:
    requests:
      storage: 20Gi

I'm confident that the tutorial needs an update; maybe we should split it into two tutorials:

How does that sound? This could be quite a bit of work.

Thanks Deva

  • setting up a storage driver, defining a StorageClass and making an initial PersistentVolume
  • working with PVCs and deploying a sample workload

How does that sound? This could be quite a bit of work.
