문제)

- Create a new PersistentVolumeClaim:

Name: app-volume

StorageClass: app-hostpath-sc

Capacity: 10Mi

- Create a new Pod which mounts the PersistentVolumeClaim as a volume:

Name: web-server-pod

Image: nginx

Mount path: /usr/share/nginx/html

- Configure the new Pod to have ReadWriteMany access on the volume.

다음 yaml 복사

$ sudo vi app-volume-pvc.yaml
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: app-volume
spec:
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 10Mi
  storageClassName: app-hostpath-sc
  
$ sudo kubectl apply -f app-volume-pvc.yaml

같은 storageClassName을 가지는 PV가 PVC에 할당된다.

전체 yaml 을 복사하여 사용한다.

$ sudo vi web-server-pod.yaml
apiVersion: v1
kind: Pod
metadata:
  name: web-server-pod
spec:
  containers:
    - name: nginx
      image: nginx
      volumeMounts:
      - mountPath: "/usr/share/nginx/html"
        name: mypd
  volumes:
    - name: mypd
      persistentVolumeClaim:
        claimName: app-volume

$ sudo kubectl apply -f web-server-pod.yaml

$ sudo kubectl describe pods web-server-pod

마운트 정보를 확인할 수 있다.
