sorry, i think i misunderstood your original ask. external-dns is more for mapping ingresses/services to dns providers

I’ve seen external-dns used for cloudflare and it looks to support powerdns as well.

Sorry, I don’t have as much experience with node management and config, so I’m not sure past that. Aside from focusing on where and how your images are being stored? That’s probably where I’d start first.

These two jumped out at me:

Warning  FreeDiskSpaceFailed  35m (x286 over 24h)  kubelet  Failed to garbage collect required amount of images. Attempted to free 12087084646 bytes, but only found 253243 bytes eligible to free.

and

Warning  InvalidDiskCapacity  21m/14m  kubelet  invalid capacity 0 on image filesystem

Sounds like maybe a disk space issue on your nodes?
