06/24/2022, 5:02 PMI might be wrong, but I think I've read that all alpha-features are removed from the k3s binary to keep the size down or something like that.

06/27/2022, 7:44 PMI’ve been trying to read the docs thoroughly. However, I can’t quite decipher whether this a per Kubernetes system component thing or not. The cluster where I’m trying this, being a v1.23.6 should do it. However, I’m not 100% on how I enable alpha features.
Thank you

06/28/2022, 5:58 PM@creamy-pencil-82913 does that make sense?

06/28/2022, 6:05 PMthe kubelet is what does the actual probing, so you probably need to enable the feature-gate there as well. Have you done so?
creamy-pencil-82913
06/28/2022, 6:07 PMthe Kubernetes docs don’t ever tell you which components need a particular feature-gate, so if something’s not working right it’s usually best to enable it on all of them (apiserver, controller-manager, scheduler, kubelet) until you can figure out which ones actually need it.

06/28/2022, 6:10 PMAah right - thank you! Pretty complex to figure this out then
late-needle-80860
06/28/2022, 6:10 PMNope I haven’t enabled it on the kubelet - how do I do so for

06/29/2022, 7:39 AMHmm okay fair. Just added a pic. Where I showed what I'm doing. Today I'm using kube-apiserver-arg
late-needle-80860
07/01/2022, 2:49 PMSo I've tried with all these arguments now. However, these are only configured on control-plane nodes so when a gRPC probe test workload goes to a worker it doesn't work.
If I make the workload tolerate the control-plane taint and cordon all workers the workload goes to X control-plane node and it works.
So I need to configure the kubelet I guess? At least it's the only K3s/Kubernetes arg. That makes sense in this context. Am I right?

creamy-pencil-82913
07/01/2022, 5:08 PMyes, you need to enable the feature-gate on all the components that use it

07/01/2022, 6:10 PMAlright. Thank you! Trying …. really requires some investigation this alpha feature thingy

07/02/2022, 12:13 AMSo gRPC probes can be had on k3s workers with the use of the
