7. 接下来, 我们要给我们的集群添加 GlusterFS 的 永久存储( Persistent Volume )

# 首先, 给 gluster 创建 service

# 端口是会被忽略的, 所以写 1 就可以

$ oc create -f gluster-svc.yaml

apiVersion: v1
kind: Service
metadata:
  name: glusterfs-cluster
spec:
  ports:
    - port: 1

# 然后, 创建 endpoint

$ oc create -f gluster-endpoint.yaml

apiVersion: v1
kind: Endpoints
metadata:
  name: glusterfs-cluster
subsets:
  - addresses:
      - ip: 192.168.1.201
    ports:
      - port: 1
  - addresses:
      - ip: 192.168.1.202
    ports:
      - port: 1
  - addresses:
      - ip: 192.168.1.203
    ports:
      - port: 1

# 最后, 创建 pv

$ oc create -f gluster-volume.yaml

apiVersion: v1
kind: PersistentVolume
metadata:
  name: glusterfs-volume
spec:
  capacity:
    storage: 60Gi
  accessModes:
    - ReadWriteMany
  glusterfs:
    endpoints: glusterfs-cluster
    path: openshift
    readOnly: false
  persistentVolumeReclaimPolicy: Retain

# 查看一下 PV

$ oc get pv

NAME               CAPACITY   ACCESSMODES   RECLAIMPOLICY   STATUS      CLAIM     STORAGECLASS   REASON    AGE

glusterfs-volume   60Gi       RWX           Retain          Available                                      2m

8. 我们给 docker-registry 创建一个 pvc

$ oc create -f docker-registry-pvc.yaml

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: docker-registry-pvc
spec:
  resources:
    requests:
      storage: 10Gi
  accessModes:
    - ReadWriteMany
  volumeName: glusterfs-volume

# 查看一下 pvc

$ oc get pvc
NAME                  STATUS    VOLUME             CAPACITY   ACCESSMODES   STORAGECLASS   AGE
docker-registry-pvc   Bound     glusterfs-volume   60Gi       RWX                          4s

# 编辑一下 dc/docker-registry, 使用 pvc

$ oc edit dc docker-registry

......
      volumes:
      - emptyDir: {}
      - persistentVolumeClaim:
          claimName: docker-registry-pvc
        name: registry-storage
......

至此, OpenShift Origin 就部署完成了
