[英]How to directly mount external NFS share/volume in kubernetes(1.10.3)
I am using kubernetes : v1.10.3 , i have one external NFS server which i am able to mount anywhere ( any physical machines). 我正在使用kubernetes:v1.10.3,我有一台外部NFS服务器,可以将其安装在任何地方(任何物理机器)。 I want to mount this NFS directly to pod/container .
我想将此NFS直接安装到pod / container。 I tried but every time i am getting error.
我尝试过,但每次遇到错误时。 don't want to use privileges, kindly help me to fix.
不想使用特权,请帮助我修复。

尾巴左右。
NFS server : mount -t nfs 10.X.X.137:/stagingfs/alt /alt
I added two things for volume here but getting error every time. 我在这里增加了两件事,但是每次都会出错。

As stated in the error log: 如错误日志中所述:
for several filesystems (e.g. nfs, cifs) you might need a /sbin/mount. helper program
According to this question , you might be missing the nfs-commons package which you can install using sudo apt install nfs-common
根据这个问题 ,您可能会缺少可以使用
sudo apt install nfs-common
安装的nfs-commons软件包。
