Linux 无法装载停靠的NFS服务器：不支持请求的NFS版本或传输协议

我的docker引擎在Ubuntu 16上运行

我尝试基于以下内容设置NFS服务器：使用

NFS服务器正在运行。集装箱IP为172.17.0.2

但我不能安装在同一个容器或从其他容器

错误：

Please try, as root, 'mount -t nfsd nfsd /proc/fs/nfsd' and then restart rpc.nfsd to correct the problem

docker

容器仍在使用主机的内核，因此它们只能访问主机编译和加载的设施。因此，您无法避免需要加载（如果模块化）或重新编译（如果不是）内核模块，这些模块是功能的有效先决条件。您是否使用

docker run

命令中的

--privileged

标志运行容器？
