[Failing Test] UserNamespacesSupport feature gate kernel version requirements should not apply generally
aojea opened this issue · 4 comments
This is breaking the kind job that monitors the state of a cluster with alpha features enabled
https://testgrid.k8s.io/sig-testing-kind#kind-master-alpha-beta
The kubelet fails to start https://storage.googleapis.com/kubernetes-jenkins/logs/ci-kubernetes-e2e-kind-alpha-beta-features/1789720580090499072/artifacts/kind-control-plane/kubelet.log
May 12 18:23:54 kind-control-plane kubelet[299]: E0512 18:23:54.927628 299 run.go:72] "command failed" err="failed to run Kubelet: failed to create kubelet: the kernel version (5.15.0) is incompatible with the UserNamespacesSupport feature gate, which needs 6.3 as a minimum kernel version"
If I understand the feature correctly, the enablement of the feature gate does not necessary means that kernel version is required.
It seems the feature gate is being used as a flag that is incorrect, as if this graduates it will be always enabled, and we can not require UserNamespacesSupportKernelVersion for ALL the cluster
@dims @AkihiroSuda can you please relax this validation to check the kernel version supported ONLY when the feature is actually used? or emit a warning, I'm not familiar enough with the feature
