用statefulSet 部署持久化的OA（Tomcat）

1.部署多个副本的OA（Tomcat）集群，其中一个Tomcat的需要加一个定时器，其他代码跟其他的Tomcat的代码一样。需要重启后也还是保持这个状态。代码如下：

apiVersion: v1
kind: Service
metadata:
  name: wordpress0217
  labels:
    app: wordpress0217
spec:
  ports:
  - port: 80
  clusterIP: None
  selector:
    app: wordpress0217
    tier: frontend0217
---
---
apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: wordpress0217
  labels:
    app: wordpress0217
spec:
  serviceName: wordpress0217
  replicas: 2
  selector: 
    matchLabels:
      app: wordpress0217
      tier: frontend0217
  template:
    metadata:
      labels:
        app: wordpress0217
        tier: frontend0217
    spec:
      containers:
      - image: harbor.loveme.cn/pub/oatomcat:0220
        name: wordpress0217
        env:
        - name: WORDPRESS_DB_HOST
          value: wordpress0218-mysql
        - name: WORDPRESS_DB_PASSWORD
          value: engine2user
        ports:
        - containerPort: 8080
          name: wordpress0217
        volumeMounts:
        - name: wordpress-persistent-storage
          mountPath: /usr/local/tomcat/webapps/ROOT/
  volumeClaimTemplates:
  - metadata:
       name: wordpress-persistent-storage
    spec:
         accessModes: [ "ReadWriteOnce" ]
         storageClassName: rook-ceph-block
         resources:
           requests:
             storage: 20Gi
