Have a few questions around possible deployment
a) Can one effectively do a multi-arch cluster deployment, say some
x86_64 and some aarch64 nodes?
No idea. Just try it.
- this might be relevant mostly to have designated
nodes of the respective variety for targeted workloads
b) Parallel to above, would it be possible, given the kubeadm-based
approach to include a worker node based on another Linux (with
Kubernetes installed) distribution?
As long as kubeadm/kubelet have the same version as the rest of the
cluster: nobody cares about the underlying OS, so yes, this should
- as above, this might enable usage of other enabled
Jetson/RPi4 which don't yet have openSUSE images available
c) From the https://en.opensuse.org/Kubic:kubeadm
wiki page, it cites
being able to have a single master node (and untaint to allow workload
scheduling there). For edge computing (aka gateways), this might be a
quite valid usage scenario. Other than potential resource conflicts of
such a single node "cluster", any other considerations/caveats?
And a couple of issues ...
1) on the same wiki page cited above, for Cilium it cites using
/usr/share/k8s-yaml/cilium/cilium.yaml but the file currently residing
there is /usr/share/k8s-yaml/cilium/quick-install.yaml. Is this the
correct one to now use?
As already written on this list: cilium is currently broken and it's
a lot of work to get it building correct again. No idea how far we are
2) for some reason, all of the nodes in a recent
deployed cluster show
Status = NotReady (which may be related to previously listed issue and
my assumption to use the file in that directory), since kubectl
describe node <name> shows an error ... "Missing CNI default network"
"Missing CNI default network" means you haven't installed one.
Seems you missed a step in the setup or made a mistake somewhere.
