安装nfs服务器

systemctl stop rpcbind.socket
systemctl stop rpcbind
systemctl disable rpcbind.socket 
systemctl disable rpcbind

mkdir -p ~/nfs/files
chmod -R 777 ~/nfs/files
echo "/files *(rw,sync,no_subtree_check,fsid=0,no_root_squash)" > ~/nfs/exports.txt

docker run --name nfs -d --rm\
  -v ~/nfs/files:/files\
  -v ~/nfs/exports.txt:/etc/exports:ro\
  --cap-add SYS_ADMIN\

使用showmount命令查看效果

使用rancher把nfs挂载到k8s上

查看效果

部署jenkins

在rancher上创建一个新的部署

指定workspace路径为nfs

查看效果

核对rancher生成的配置文件
