2. FileStroage (NFS) 연결 Pod

  • NFS 연결을 위한 PersistentVolume 생성
apiVersion: v1
kind: PersistentVolume
metadata:
  name: pv-nfs
  labels:
    pv: pv-nfs
spec:
  capacity:
    storage: 2G
  accessModes:
  - ReadWriteMany
  nfs:
    path: /share-data
    server: xxx.xxx.xxx.xx
  • PersistentVolumeClaim
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: pvc-nfs
spec:
  accessModes:
  - ReadWriteMany
  resources:
    requests:
      storage: 2G
  storageClassName: ""
  selector:
    matchLabels:
      pv: pv-nfs
  • Pod
apiVersion: v1
kind: Pod
metadata:
  name: pod-nfs
spec:
  containers:
  - name: container
    image: kubetm/init
    volumeMounts:
    - name: volume-nfs
      mountPath: /nfs/share-data
  volumes:
  - name : volume-nfs
    persistentVolumeClaim:
      claimName: pvc-nfs
