Change
For Kube control plane components launched as static pods For pods across all the openshift namespaces
How
(a) Enabling pre-compiled admission controller ‘MutatingAdmissionWebhook’ to inject required resource requests/limits values for pods across all the openshift namespaces (admission-webhook.yaml) (b) Resources requests/limits are updated in the manifest files of Kube control plane components (launched as static pods by Kubelet) (update-kube-controlplane.sh)
Implemented in https://github.com/code-ready/snc/pull/246
