Public bug reported:
MicroK8s has a requirement for the kernel module `br_netfilter` so that
it can properly set up all networking related configurations and get a
functioning Kubernetes cluster. In Raspberry Pi, this kernel module is
part of the extra modules package and not part of main.
This leads to two issues:
- People installing MicroK8s on a fresh Raspberry Pi install get a non-
working Kubernetes cluster, and it's not a great experience having to
manually install extra kernel modules for things to work correctly.
- Currently, Ubuntu Core does not support loading external kernel
modules at all, so it is a hard blocker for running MicroK8s on Ubuntu
Core on Raspberry Pi.
As such, we want to request that the `br_netfilter` module is promoted
from extras to main, so that it is available by default on new installs
and get a better out of the box experience. Further, it will unblock
people trying out MicroK8s with Ubuntu Core on Rasbperry Pi.
Finally, it is worth noting that br_netfilter is part of the main
modules in amd64 kernels.
As far as the MicroK8s team is concerned, we would like this change to be
available primarly in LTS kernels (22.04, 20.04) but also in normal releases (i
believe 22.10 and 23.04 would be enough).
Happy to provide more details or information if needed.
