metadata:
  name: wordpress
  namespace: wordpress
  labels:
    app: wordpress
spec:
  containers:
  - name: wordpress
    image: wordpress
    ports:
    - containerPort: 80
      name: wdport
    resources:
      limits:     ##资源的限制
        cpu: "20m"
        memory: 512Mi
      requests:   ###给pod分配的资源
        cpu: "10m"
        memory: 128Mi
    env:
    - name: WORDPRESS_DB_HOST
      value: 127.0.0.1:3306

    - name: WORDPRESS_DB_USER
      value: wordpress
    - name: WORDPRESS_DB_PASSWORD

    imagePullPolicy: IfNotPresent
  - name: mysql
    image: mysql:5.7
    imagePullPolicy: IfNotPresent
    ports:
    - containerPort: 3306
      name: dbport
    resources:
      limits:     ##资源的限制
        cpu: "20m"
        memory: 512Mi
      requests:   ###给pod分配的资源
        cpu: "10m"
        memory: 128Mi
    env:

    volumeMounts:
    - name: db
      mountPath: /var/lib/mysql
  volumes:
    - name: db
      hostPath:
        path: /var/lib/mysql

  name: wp-svc
  namespace: wordpress
spec:
  ports:
  - port: 8081
    protocol: TCP
    targetPort: 80

[root@node1 yaml]# kubectl apply -f wordpress.yaml 
namespace/wordpress created
pod/wordpress created
service/wp-svc created
[root@node1 yaml]# kubectl get po -n wordpress -o wide
