Thanks for the post. I ran into the same issue with assigning IPv6 addresses to k8s pods. Wish there were easier solutions to handle the prefix changing.

A good advise: Never use a real range for the PODs.

I run K3s, and it's not supported to change the internal ranges after creating the cluster.

On the ingress, i.e. with metalLB, it's different, of course. And that is what my solution is for.

I'm going to improve it in the coming weeks. It's not going to be any easier, though, it will just be more fun for me :) (I like to learn new stuff).

It's probably going to be a bit more robust and logical, though, not look as hacked-together than my current script. But unless I actually get around to making a plugin architecture for it, it's still going to assume you're using a Unifi gateway.
