安装NFS
在master安装NFS
systemctl start nfs-server
修改配置 /etc/exports
/data *(rw,no_root_squash,no_all_squash,sync)
目录为 /data 允许所有地址访问
验证下
[root@master nginx]# showmount -e 192.168.57.61
Export list for 192.168.57.61:
/data *
共享可以正常访问
K8S部署nginx
新建 nginx.yaml
apiVersion: apps/v1

在deployment 配置中
volumeMounts:- name: datamountPath: /usr/share/nginx/htmlvolumes:- name: datanfs:path: /dataserver: 192.168.57.61
这部分代表 容器内的 /usr/share/nginx/html 目录
挂到NFS 的 /data目录
NFS服务器的地址为 192.168.57.61
在Service中
apiVersion: v1
kind: Service
metadata:name: nginx-servicelabels:app: nginx
spec:ports:- port: 9000name: nginxprotocol: TCPtargetPort: 80nodePort: 31090selector:app: nginxtype: NodePortports:port:9000 代表pod之间通信的端口为9000
protocol：TCP 代表只允许TCP连接
targetPort:80 代表pod内的80端口
nodePort:31090 代表映射到集群外的31090端口，刚才提到的80端口
运行
kubectl apply -f nginx.yaml
查看pod状态（由于我没有设置namespace 就是默认的命名空间 不用指定 -n ）
[root@master nginx]# kubectl get pod
NAME READY STATUS RESTARTS AGE
nginx-deployment-5d7bfd6588-6g5mn 1/1 Running 0 48m
nginx-deployment-5d7bfd6588-7sz4p 1/1 Running 0 48m
nginx-deployment-5d7bfd6588-vkbvq 1/1 Running 0 48m
测试
挂载NFS
mount -t nfs -o rw 192.168.57.61:/data /data1
echo "11111" >> /data1/index.html 访问：http://192.168.57.76:31090/
可以看到1111 已经显示在浏览器中了
index.html已经在容器内了
