1 生成ceph-secret

cat /etc/ceph/ceph.client.admin.keyring 
[client.admin]
    key = AQDlG99ZVJhfExAAFVT/ttJBgqOKcyY5INX5Cw==

將key base64處理
echo "AQDlG99ZVJhfExAAFVT/ttJBgqOKcyY5INX5Cw=="|base64

2 創(chuàng)建secret

cat ceph-secret.yml 
apiVersion: v1
kind: Secret
metadata:
  name: ceph-secret
data:
  key: QVFEbEc5OVpWSmhmRXhBQUZWVC90dEpCZ3FPS2N5WTVJTlg1Q3c9PQo=

3 創(chuàng)建pvc

cat ceph-pvc.yml 
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: cephfs
spec:
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 8Gi

4 創(chuàng)建pv

cat ceph-pv.yml 
apiVersion: v1
kind: PersistentVolume
metadata:
  name: cephfs
spec:
  capacity:
    storage: 10Gi
  accessModes:
    - ReadWriteMany
  cephfs:
    monitors:
    - 192.168.100.96:6789
    path: /
    user: admin
    secretRef:
      name: ceph-secret

5 創(chuàng)建RC

cat app-rc.yaml 
apiVersion: v1
kind: ReplicationController
metadata:
  name: rc-fish
  labels:
    name: fish
spec:
  replicas: 1
  template:
    metadata:
      labels:
        app: fish
    spec:
      containers:
      - name: fish
        image: registry:5000/fish:7.5
        imagePullPolicy: IfNotPresent
        ports:
        - containerPort: 80
          protocol: TCP
        resources:
          limits:
            cpu: 100m
            memory: 128Mi
        volumeMounts:
        - name: cephfs
          mountPath: /var/log/nginx
      volumes:
      - name: cephfs
        persistentVolumeClaim:
          claimName: cephfs
