I use next command to start lavadispatcher:

docker run -idt --net=host --privileged -v /dev:/dev -v /var/lib/lava/dispatcher/tmp:/var/lib/lava/dispatcher/tmp -e "DISPATCHER_HOSTNAME=--hostname=myname" -e "LOGGER_URL=tcp://master_ip:5555" -e "MASTER_URL=tcp://master_ip:5556" --name test_lava lavasoftware/lava-dispatcher:2019.01

In container, I start tftp and nfs. But the nfs always cannot be start successfully. I use "service nfs-kernel-server start" to start it, also before that I did "rpcbind".

The start shows below seems ok:
# service nfs-kernel-server start
[ ok ] Exporting directories for NFS kernel daemon....
[ ok ] Starting NFS kernel daemon: nfsd mountd.

But if do next we can see the nfs still not start.
# service nfs-kernel-server status
nfsd not running

Any suggestion?
