Support for nftables #2034
Description
Is your feature request related to a problem? Please describe
I'm using k3s and thus -- as I understand the dependencies -- implicitly kube-router.
I had to upgrade my nodes to AlmaLinux 10 for non-kubernetes related reasons. Now i'm getting lot's of warnings that I'm using a non maintained feature: iptables.
From my understanding k3s requires kube-router to support nftables in order to, well, support nftables (k3s-io/k3s#12849). (Sorry, but I had chosen k3s in order to not needing a deep understanding about all this.)
I have searched and couldn't find anything about an already started effort to make kube-router support nftables.
Describe the solution you'd like
A switch to make kube-router use nftables instead of iptables
Describe alternatives you've considered
As far as I have understood things, I'd have to replace k3s with some other kubernetes distribution or assemble one myself.
Additional context
RHEL 9 will still be supported until 2032. But that's not that far in the future. RHEL 10 is here since about a year and has already had it's first minor update. So I think we'll see more and more new installations using RHEL 10
