        tier: backend
    spec:
      enableServiceLinks: false
      volumes:
        - name: nginx-php-vol #直接这里弄个跟随pod的存储卷，不需要单独建存储卷了
          emptyDir: {}
        - name: nginx-cnfig-vol
          configMap:
            name: nginx-php-config

      containers:

          image: laravel-php
          imagePullPolicy: Never
          volumeMounts:
            - name: nginx-php-vol
              mountPath: /code
          lifecycle:
            postStart:
              exec:
                command: [ "/bin/sh", "-c", "cp -r /var/www/html/. /code" ]
        - name: nginx
          image: nginx:1.21.0

Service 配置文件

apiVersion: v1
kind: Service

相比双pod 简洁了不少，这也是绝大多数推荐的方式，不符合单一原则，但是谁让phpfpm+nginx本身就不合规矩呢
