Forwarding this to centos-devel, as that's where other discussions
around kubernetes rebuild[s] takes place too.
What would be the best way to to have people from armhfp world
discussing with the people managing/maintaing k8s on cbs.centos.org ?
Just opening a thread about this, but it's good to know that :
- people are willing to (re)build it for armhfp
- and that it works with just rebuilding the src.rpm from cbs.centos.org
(covering so far x86_64, while aarch64, ppc64le are also other available
target arches in koji/cbs)
BTW, kudos to Wagner Sartori (trunet) for the rebuild ! :-)

Subject: {Disarmed} [Arm-dev] Kubernetes support on ARM32

Hey, what's up!
I finished building all needed packages to bring kubernetes to ARM. All
of them were brought by simply copying src packages from CBS and doing
minor or no changes at all.
To my surprise, kubeadm ran perfectly fine, it got the correspondent arm
image for each component. I went with weave for pod network layer, as it
have network policy and ARM support.
Manual changes, was to symlink all files under /opt/cni/bin into
/usr/libexec/cni, otherwise the pods will not find the cni plugins and
doesn't start (like kube-dns stuck at containercreating). And
kubernetes-dashboard, you need to change tha image to be arm instead of
amd64.
