Thanks Tycho, I was able to install the nfs-kernel-server on the LXD container. I ran the steps for setting the default lxc profile and making the container as privileged on the host machine. After this I deployed my charm and it worked fine.

IIRC juju uses the default profile for LXD, so you could do something like: lxc profile set default raw.apparmor "mount fstype=nfs, mount fstype=nfs4, mount fstype=nfsd, mount fstype=rpc_pipefs," You'll also need to make sure the container is privileged, as unprivileged mounting of nfs is not supported by the kernel right now: lxc profile set default security.privileged true Tycho > By doing this and further steps of installing nfs server and nfs client, I > was able to share files between the LXC containers. > > Now when I run the same charm on Juju 2.0(LXD containers), my charm fails > as the nfs-kernel-server installation fails.
