Kubernetes(k8s)中部署项目wordpress(php博客项目，数据库mysql)

要在Kubernetes中部署WordPress项目，您需要定义一个配置文件，其中包含了WordPress应用程序和MySQL数据库的定义。以下是一个简化的例子，展示了如何使用Kubernetes部署WordPress和MySQL。

首先，创建一个名为wordpress-deployment.yaml的文件来定义WordPress部署和服务：

apiVersion: v1
kind: Service
metadata:
  name: wordpress-mysql
  labels:
    app: wordpress
spec:
  ports:
    - port: 3306
  selector:
    app: wordpress
    component: mysql
  clusterIP: None
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: wordpress-mysql-pv-claim
  labels:
    app: wordpress
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 250Mi
---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: wordpress
  labels:
    app: wordpress
spec:
  replicas: 1
  selector:
    matchLabels:
      app: wordpress
      component: wordpress
  template:
    metadata:
      labels:
        app: wordpress
        component: wordpress
    spec:
      containers:
        - name: wordpress
          image: wordpress:latest
          ports:
            - containerPort: 80
              name: wordpress
          env:
            - name: WORDPRESS_DB_HOST
              value: wordpress-mysql
            - name: WORDPRESS_DB_USER
              value: wordpress
            - name: WORDPRESS_DB_PASSWORD
              valueFrom:
                secretKeyRef:
                  name: mysql-pass
                  key: password
            - name: WORDPRESS_DB_NAME
              value: wordpress
          volumeMounts:
            - name: wordpress-persistent-storage
              mountPath: /var/www/html
        - name: mysql
          image: mysql:5.7
          env:
            - name: MYSQL_ROOT_PASSWORD
              valueFrom:
                secretKeyRef:
                  name: mysql-pass
                  key: password
            - name: MYSQL_DATABASE
              value: wordpress
          ports:
            - containerPort: 3306
              name: mysql
          volumeMounts:
            - name: wordpress-persistent-storage
              mountPath: /var/lib/mysql
      volumes:
        - name: wordpress-persistent-storage
          persistentVolumeClaim:
            claimName: wordpress-mysql-pv-claim
---
apiVersion: v1
kind: Service
metadata:
  name: wordpress
  labels:
    app: wordpress
spec:
  ports:
    - port: 80
  selector:
    app: wordpress
    component: wordpress
  type: LoadBalancer

然后，创建一个名为mysql-secret.yaml的文件来定义M
