Make ReadWriteMany work without nfs.

[steveiliop56]

Hi!

I recently built my first k3s cluster with my one pi4 and wanted to install drupal ( because its awesome :) ) so with the help of chatGPT and your drupal.yml I created this manifest file ( Note that the volume that I want must be mounted in /data/drupal-files/ on the raspberry pi and in /var/www/html on the container. ):

apiVersion: apps/v1
kind: Deployment
metadata:
  name: drupal-deployment
spec:
  replicas: 1
  selector:
    matchLabels:
      app: drupal
  template:
    metadata:
      labels:
        app: drupal
    spec:
      containers:
        - name: drupal
          image: drupal:latest
          ports:
            - name: http
              containerPort: 80
          volumeMounts:
            - name: drupal-files
              mountPath: /var/www/html
      volumes:
        - name: drupal-files
          persistentVolumeClaim:
            claimName: drupal-pvc
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: drupal-pvc
spec:
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 1Gi
---
apiVersion: v1
kind: Service
metadata:
  name: drupal-service
spec:
  ports:
    - name: http
      port: 7000
      targetPort: 80
  selector:
    app: drupal
  type: LoadBalancer

But while the pods and the service work, the persistent volume claim does not want to start, it's stuck on pending. When I run sudo kubectl describe pvc it gives me this output:

Name:          drupal-pvc
Namespace:     default
StorageClass:  local-path
Status:        Pending
Volume:
Labels:        <none>

               volume.kubernetes.io/selected-node: raspberrypi4
               volume.kubernetes.io/storage-provisioner: rancher.io/local-path

  Normal  WaitForFirstConsumer  10s               persistentvolume-controller  waiting for first consumer to be created before binding
  Normal  ExternalProvisioning  2s (x2 over 10s)  persistentvolume-controller  waiting for a volume to be created, either by external provisioner "rancher.io/local-path" or manually created by system administrator

I tried creating a volume mapped to /data/drupal-files but it still does not work. Lastly I want to note that the ReadWriteOnce mode works fine.

Thanks in advance, RaspberryDeveloper :)
