我的docker引擎在Ubuntu 16上运行。
我尝试根据以下方式设置NFS服务器：使用https://github.com/ErezHorev/dockerized_nfs_server/blob/master/docker/Dockerfile
NFS服务器现在正在运行。容器IP是172.17.0.2
但我无法安装在同一个容器或其他容器中。
错误：

我跑的时候
service nfs-kernel-server start
mount: permission denied
* Exporting directories for NFS kernel daemon...
exportfs: could not open /proc/fs/nfs/exports for locking: errno 13 (Permission denied)
[ OK ]
* Starting NFS kernel daemon rpc.nfsd: Unable to access /proc/fs/nfsd errno 2 (No such file or directory).
Please try, as root, 'mount -t nfsd nfsd /proc/fs/nfsd' and then restart rpc.nfsd to correct the problem
