MaaS only with DHCP managed seems to require DNS too.

[Thiago Martins]

Guys,

 After too much trouble with maas-dns, I decided to not use it, so, I reinstalled MaaS without maas-dns package and when I select "Manage DHCP", the following error appear:

/var/log/maas/celery-region.log

DNSConfigDirectoryMissing: The directory where the DNS config files should be written does not exist. Make sure the 'maas-dns' package is installed on this region controller.

 But yes, I do not want maas-dns package.

 So, what can I do?!

Tks,
Thiago

I think it might makes sense to make MAAS owns DHCP without DNS, but that's not the case currently.

MAAS either manages DHCP and DNS or you have to manage both yourself.

[Raphaël Badin (rvb)]

MAAS supports managing DHCP but not DNS. The problem is that the task 'write_full_dns_config' (connected via signals) is always triggered (when a nodegroup is changed or a node updated). We simply need to skip actually trying to write the configuration if none of the cluster has been configured to manage DNS.

Workaround: simply ignore the error and do not install maas-dns if you don't want to have MAAS manage a DNS server.
