进阶版部署nginx，使用nfs持久化nginx的 html 和 log 文件

# 1.搭建NFS储存

这里不赘述

# 2.创建nginx的configMap

[root@master ~]# kubectl create configmap nginx-configmap --from-file=${DIR}/nginx/conf/nginx.conf
configmap/confnginx created
# 查看是否创建成功
[root@master ~]# kubectl get configmap 
NAME               DATA   AGE
nginx-configmap    1      23s

# 3.创建PV和PVC

      - name: vol-html
        persistentVolumeClaim: 
          claimName: nhtml-pvc

# 4.执行yml文件

注意顺序，一般先创建PV，然后PVC申请PV资源，再创建服务与pod

[root@master ~]# kubectl create -f  ${DIR}/nginx/pv.yml
[root@master ~]# kubectl create -f  ${DIR}/nginx/pvc.yml
[root@master ~]# kubectl create -f  ${DIR}/nginx/service.yml
[root@master ~]# kubectl create -f  ${DIR}/nginx/pod.yml

、

# 5.验证

[root@master]# kubectl get svc
NAME            TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)           AGE
