容器部署时，后端换成nfs共享，出错

服务器问题
1

参照开源版部署方法.md部署成功后，参考NFS 下集群安装将后端换成nfs，使用原先的配置文件docker-compose.yml启动时报错如下，请问后端是否容器部署暂时不支持更换后端？

容器中是不能这么单纯的设置软链接的，你在宿主机上设置的软链接到通过volumes挂载到容器中后，软链接就成了容器自己的软链接了，所以你应该把nfs的目录也相应的挂载到容器中，不知道这么说你能明白不

是指在容器内使用mout.nfs或mount -t nfs命令挂载宿主机的vol吗？
目前采用docker-impose提供的image进行部署的，该image里好像不能进行nfs挂载

root@80d73ff24682:/# showmount -e
bash: showmount: command not found
root@80d73ff24682:/# mount.nfs
bash: mount.nfs: command not found
root@80d73ff24682:/# mount -t nfs XXX.XXX.XXX.XXX:/mnt/vol /seafile-nfs
mount: /seafile-nfs: permission denied.

不是在容器中直接挂载nfs，而是要把宿主机上挂载的那一套nfs目录作为容器的volumes挂载到容器中，使得在宿主机上创建的软链接到容器中还能指向正确的目标目录。
