I did find a post from… 2018, saying that DNS/DHCP is meant to be externally managed in clusters. surely this has changed in the 8 years since.
LXD clustering right now very much assumes that you have an existing layer-2 infrastructure and that you’ll effectively just plug your containers into an existing physical network (VLAN) with a router provided DHCP/DNS for you. That’s the case which works best and if integrated with MAAS, LXD can even do IP management for you in this case.
Emphasis mine, since I am aware of all the other things in that comment already and I’m sure that it’ll be pointed out to me yet again if I don’t say so. (once again, as described, I have this setup. The exact setup being described here, the one with VLANs, is my setup, which I have and it works. I am specifically asking about DHCP/DNS)
Is this still the case? Are you assumed to use external DNS/DHCP in an Incus cluster? If so, what is all the logic around DHCP leases for?
