How to get kubernetes to add all its internal dns entries to your own dns server (lemmy.zip)

By this I mean, I have a powerdns server running in my cluster, I would like Kubernetes to add/update dns entries in my dns server to reflect all services or any domains that would be used within the cluster, this is to fix a current issue I am having, and for general control and centralization purposes.

Any idea how I do that?

With powerDNS, no. Personally, I use Fedora with podman containers. I have a pihole container utilizing unbound as my roothints resolver so all of my requests are internalized. Pihole has DHCP availability, but I utilize my gateway (Unifi) for DHCP and simply build my local DNS records manually on Pihole as needed.

I'm not sure how many Kubes you actually have, but building a local DNS entry is pretty manageable unless you have a LOT of Kubes automatically deploying themselves.

Could you explain the steps to active your setup? I'm sure I can modify it for powerdns

It's quite literally how I laid it out. I have a Fedora server with an Unbound container for roothints lookup, and a pihole container for internal DNS sevices. It's taken a lot of time to get working like any homelab stuff.

I've never heard of powerDNS but you may be in a situation where you need to read their docs or try and find other posts or videos of what you're trying to accomplish. Sorry I wasn't much more help.
