Setting up NFS server in lxd container

September 6, 2016 1-minute read

In the lxd host, suppose you have the following containers

$ lxc list
+------------+---------+-----------------------+------+------------+-----------+
|    NAME    |  STATE  |         IPV4          | IPV6 |    TYPE    | SNAPSHOTS |
+------------+---------+-----------------------+------+------------+-----------+
| base       | STOPPED |                       |      | PERSISTENT | 0         |
+------------+---------+-----------------------+------+------------+-----------+
| nfs-server | RUNNING | 192.168.31.135 (eth0) |      | PERSISTENT | 0         |
+------------+---------+-----------------------+------+------------+-----------+

Make nfs-server a privileged container

$ lxc config set nfs-server security.privileged true

and get apparmor to allow nfs-server stuff

$ lxc config set nfs-server raw.apparmor 'mount fstype=nfs*, mount fstype=rpc_pipefs,'

Then reboot.

In the lxd container,

apt-get install nfs-kernel-server

and use regular instructions to set up nfs.

Check that nfs-server is up using

$ sudo systemctl status nfs-server
[sudo] password for user:
