k8s里部署mysql数据库

先使用命令创建命名空间

kubectl create ns database

dep.yaml

apiVersion: apps/v1
kind: Deployment

  name: mysql-dep
  namespace: database

    app: mysql

        ports:

          name: app-port
          protocol: TCP
        resources:

        volumeMounts:
        - name: mysql-data
          mountPath: /var/lib/mysql
        - name: mysql-time
          mountPath: /etc/localtime
      volumes:
      - name: mysql-data
        persistentVolumeClaim:
          claimName: mysql-pvc
      - name: mysql-time
        hostPath:
          path: /etc/localtime

svc.yaml

apiVersion: v1
kind: Service
metadata:
  name: mysql-svc
  namespace: database
  labels:
    app: mysql
spec:
  selector:
    app: mysql
  type: NodePort
  ports:
  - name: database
    port: 3306
    targetPort: app-port
    nodePort: 31006

pvc.yaml

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: mysql-pvc
  namespace: database
spec:
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 10Gi

我这里是动态的存储，创建pvc出来会自动绑定pv，具体部署可参考http://www.yepblog.cn/?p=297
