migration to buildroot 2022.02

[jerome ibanes]

buildroot4kubernetes seems to work fine on buildroot-2022.02.x (stable); necessary changes:
genimage-bios.cfg: requires holes = {"(440; 512)"} in partition boot, as such:

  partition boot {
    in-partition-table = "no"
    image = "boot.img"
    offset = 0
    size = 512
    holes = {"(440; 512)"}
  }

I also recommend upgrading to the latest kernel, in buildroot_defconfig:
BR2_LINUX_KERNEL_CUSTOM_VERSION_VALUE="5.4.186"

Thanks, will do

Juggling a couple of different builds, was contemplating UEFI - but I think I will leave these as BIOS (and RPi) for now...

Minikube has the other ISOs

Thank you

If time allows, maybe also upgrade to Go 1.18.

[Anders Björklund]

At the moment, Kubernetes dictates the Go version used...

i.e. using the same go version as the official builds do

Thanks, I didn't know there was such strong dependency.

There isn't, but easier to stay with the tested version ?

Unfortunately, they normally require latest/greatest go.
So doesn't always work, to stay with the system version.

But I think that Kubernetes 1.24 is currently using go1.18

Updated to Buildroot 2022.02, ran into some cgroups v2 issues. :-(

I think I found the missing config, but in my book it is still unstable...
