I'm spawning a kube cluster with KOPS. All works fine until I added feature gate SupportPodPidsLimit to kubelet:

kubelet:
featureGates:
SupportPodPidsLimit: "true"

Master node syslog shows: Failed to set feature gates from initial flags-based config" err="unrecognized feature gate: SupportPodPidsLimit

I haven't found in KOPS or Kube docs what and why feature gates can be unknown. Kube docs say SupportPodPidsLimit exists since 1.20.0 in GA. I'm using 1.23.0

Expecting to set podPidsLimit

Have a look at the list of feature gates When the gate is GA, it is enabled by default and removed. Since you are using 1.23, the feature gate does indeed no longer exist.
