我在docker容器中安装nfs卷时遇到了一些麻烦 . 我有一个小兵（labcr3）和一个pod（httpd-php） . 您可以在下面找到所有相关细节 . 你能帮助我吗 ？
感谢致敬
物理主机（minion）能够挂载nfs卷 .
[root@LABCR3 ~]# df -h /NFS
Filesystem Size Used Avail Use% Mounted on
192.168.240.1:/mnt/VOL1/nfs-ds 500G 0 500G 0% /NFS
这里的特权模式启用了kionnetes on minion root @ LABCR3~] #cat / etc / kubernetes / config | grep PRIV KUBE_ALLOW_PRIV =“ - allow_privileged = true”

是的，是第一个使用nfs mount的pod . nfs安装在minion上，因此工作正常并且没有应用于nfs的ACL
