Hi there,
I’m using an LXD Cluster setup across three different host, i’ve been able to setup a fan network manually using the lxc network create fanbr0 bridge.mode=fan fan.underlay_subnet=a.b.c.d/24 lxc profile device add default eth0 nic nictype=bridged parent=fanbr0 name=eth0 commands.
And then once i got it attach unto the cluster the dhcp addressing works perfectly and i can login to each container, and ping to the other container on another host by pinging to it’s ip, but when i use the name of the container such as ping lxd01 it doesn’t work, i understand that this is due to the dnsmasq service, how do i get dnsmasq service to work on the fan network on LXD 3.2
