kubernete 本地持久化存儲 kube-controller-manager的日誌輸出 + pvc pv 概念 -- storageclass 概念

1.mysql持久化存儲

[root@pserver78 0415villa]# cat latestmysql.yaml |grep -v '^#'
apiVersion: v1
kind: Service
metadata:
  name: villa-mysql01
  labels:
    app: villa-mysql01
spec:
  ports:
    - port: 3306
      protocol: TCP
      targetPort: 3306
  selector:
    app: villa-mysql01
    tier: mysql01
  type: ClusterIP
---
---
apiVersion: apps/v1beta1
kind: Deployment
metadata:
  name: villa-mysql01
  labels:
    app: villa-mysql01
spec:
  strategy:
    type: Recreate
  template:
    metadata:
      labels:
        app: villa-mysql01
        tier: mysql01
    spec:
      affinity:
        nodeAffinity:
          requiredDuringSchedulingIgnoredDuringExecution:
            nodeSelectorTerms:
            - matchExpressions:
              - key: kubernetes.io/hostname
                operator: In
                values:
                - pserver137
      containers:
      - image: mysql:5.6
        name: vvvvmysql01
        env:
        - name: MYSQL_ROOT_PASSWORD
          value: 'engine'
        - name: MYSQL_PASSWORD
          value: 'engine'

        ports:
        - containerPort: 3306
          name: mysql01-port
        volumeMounts:
        - name: mysql01-persistent-storage
          mountPath: /var/lib/mysql
      volumes:
      - name: mysql01-persistent-storage
        persistentVolumeClaim:
          claimName: villa-mysql01

2.建立PVC和PV

[root@pserver78 villa]# cat  mysqlpvc01.yaml |grep -v '^#'
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: villa-mysql01
spec:
  accessModes:
  - ReadWriteOnce
  storageClassName: local-storage
  resources:
    requests:
      storage: 50Gi
---
kind: PersistentVolume
apiVersion: v1
metadata:
  name: villa-mysql01
  labels:
    app: villa-mysql01
spec:
  persistentVolumeReclaimPolicy: Retain
  storageClassName: local-storage
  capacity:
    storage: 50Gi
  accessModes:
    - ReadWriteOnce
  local:
    path: "/mnt/disks/villa-mysql01"
  nodeAffinity:
    required:
      nodeSelectorTerms:
      - matchExpressions:
        - key: kubernetes.io/hostname
          operator: In
          values:
          - pserver137

3.定義storageclass

[root@pserver78 villa]# kubectl -n villa0415   get storageClass local-storage -o yaml
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  annotations:
    kubectl.kubernetes.io/last-applied-configuration: |
      {"apiVersion":"storage.k8s.io/v1","kind":"StorageClass","metadata":{"annotations":{},"name":"local-storage","namespace":""},"provisioner":"kubernetes.io/no-provisioner","volumeBindingMode":"WaitForFirstConsumer"}
  creationTimestamp: 2018-10-31T00:33:22Z
  name: local-storage
  resourceVersion: "788"
  selfLink: /apis/storage.k8s.io/v1/storageclasses/local-storage
  uid: 92313505-dca4-11e8-a7fc-020050e80095
provisioner: kubernetes.io/no-provisioner
reclaimPolicy: Delete
volumeBindingMode: WaitForFirstConsumer

 

4.官網定義storageclass
kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
  name: local-storage
provisioner: kubernetes.io/no-provisioner
volumeBindingMode: WaitForFirstConsumer
