how do you set the /etc/resolve.conf domain on hirsute server?

I used to be able to address my old server at "dckr1.local", I setup a new hirsute server and change the /etc/hosts lien to read:

127.0.0.1 dckr1.local dckr1

and added to /etc/resolv.conf

search local
domain local

but can't get it for the life of me to work when I reboot. resolve.conf gets overwritten. Not sure if by something in systemd or something it's calling like cloud.init.
