NFS fix on LXC Host Server

Rumi, March 17, 2016July 28, 2018

NFS client on LXC seems do not work. Why? The problem is apparmor on the real machine that block any appempt to mount NFS volumes.
In order to try to minimize the security changes on apparmor I add the following lines in/etc/apparmor.d/lxc/lxc-default

# allow nfs mount everywhere

mount fstype=rpc_pipefs, 
mount fstype=nfs,

Then

$ /etc/init.d/apparmor reload

And now I was able to restart nfs-common and nfs-kernel-server without errors !

Update!!!!!

nano /etc/apparmor.d/lxc/lxc-default

Update the file as below-

# Do not load this file. Rather, load /etc/apparmor.d/lxc-containers, which
# will source all profiles under /etc/apparmor.d/lxc

profile lxc-container-default flags=(attach_disconnected,mediate_deleted) {
#include <abstractions/lxc/container-base>

# the container may never be allowed to mount devpts. If it does, it
# will remount the host's devpts. We could allow it to do it with
# the newinstance option (but, right now, we don't).
# deny mount fstype=devpts,

# allow nfs mount everywhere

mount fstype=rpc_pipefs,
mount fstype=nfs,
}
