（2）Pod的yaml文件

apiVersion: v1
kind: Pod
metadata:
  name: lamp-edusoho
  labels:
    app: lamp-edusoho
restartPolicy: Always
spec:
  containers:
  - name: nginx
    abels:
      app: lamp-nginx
    image: dockerhub.datagrand.com/global/nginx:v1
    ports:
    - containerPort: 80
    volumeMounts:
      - name: datadir
        mountPath: "/var/log/nginx/error.log"
        subPath: ./nginx/log/error.log
      - name: datadir
        mountPath: "/etc/nginx/nginx.conf"
        subPath: ./nginx/conf/nginx.conf
      - name: datadir
        mountPath: "/usr/share/nginx/html"
        subPath: ./nginx/edusoho
  - name: php
    image: dockerhub.datagrand.com/global/php:v1
    ports:
    - containerPort: 9000
    volumeMounts:
      - mountPath: /usr/local/php/etc/php-fpm.conf
        name: datadir
        subPath: ./php/php-fpm.conf
      - mountPath: /usr/local/php/etc/php-fpm.d/www.conf
        name: datadir
        subPath: ./php/www.conf
      - mountPath: /usr/local/php/etc/php.ini
        name: datadir
        subPath: ./php/php.ini
      - mountPath: /usr/local/php/var/log/php-fpm.log
        name: datadir
        subPath: ./php/log/php-fpm.log
      - mountPath: /usr/share/nginx/html
        name: datadir
        subPath: ./nginx/edusoho
  - name: mysql
    image: dockerhub.datagrand.com/global/mysql:5.6
    ports:
    - containerPort: 3306
    env:
      - name: MYSQL_ROOT_PASSWORD
        value: "123456"
      - name: MYSQL_DATABASE
        value: "edusoho"
      - name: MYSQL_USER
        value: "edusoho"
      - name: MYSQL_PASSWORD
        value: "edusoho"
    args: [‘--character-set-server=utf8‘]
    volumeMounts:
      - name: datadir
        mountPath: "/var/lib/mysql"
        subPath: ./mysql/data
      - name: datadir
        mountPath: "/etc/my.cnf"
        subPath: ./mysql/conf/my.cnf
  volumes:
  - name: datadir
    persistentVolumeClaim:
      claimName: nfs-pvc

（3）PV的yaml文件

apiVersion: v1
kind: PersistentVolume
metadata:
  name: nfs-pv
spec:
  capacity:
    storage: 4Gi
  accessModes:
    - ReadWriteMany
  nfs:
    server: 192.168.246.168  ##NFS服务器的ip地址
    path: "/data"  ##NFS服务器上的共享目录

（4）PVC的yaml文件

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: nfs-pvc
spec:
  accessModes:
    - ReadWriteMany
  storageClassName: ""
  resources:
    requests:
      storage: 3Gi

（5）Service的yaml文件

apiVersion: v1
kind: Service
metadata:
  name: edusoho
  labels:
    app: edusoho
spec:
  type: NodePort 
  ports:
  - port: 80
    nodePort: 32756
  selector:
    app: lamp-edusoho

（6）使用命令汇总

查看Pod
kubectl get po -o wide
查看Service
kubectl get svc
进入容器内部某个应用，如这里的nginx
kubectl exec -it lamp-edusoho -c nginx /bin/bash

（7）访问安装Edusoho平台

http://192.168.246.168:32756/install/start-install.php
说明：这里的192.168.246.168是kubernetes的node节点IP，32756是Service中定义的nodePort。
