I am new to k8s. I am following official tutorial on setting up Nginx pods in k8s using minikube, mounting a volume and serving index.html.

When I mount and go to hompe page, i receive this error that directory index of "/usr/share/nginx/html/" is forbidden.

If I dont mount anything, i receive a "Welcome to Nginx" page.

This is the content of that folder before mount. And after mount is empty

root@00c1:/usr/share/nginx/html# ls -l
total 8
-rw-r--r-- 1 root root 494 Jul 23 11:45 50x.html
-rw-r--r-- 1 root root 612 Jul 23 11:45 index.html

Why is mounted folder inside pod empty after mounting?

This is my setup

apiVersion: v1

  name: task-pv-volume
  labels:
    type: local
spec:
  storageClassName: manual
  capacity:
    storage: 10Mi

          image: nginx
          ports:
            - containerPort: 80
              name: "http-server"
          volumeMounts:
            - mountPath: "/usr/share/nginx/html"
              name: task-pv-storage
