Pods with namespace 'kube-system', or labeled with 'app.starlingx.io/component=platform' are identified as 'platform'. These have isolated cpu affinity cpuset when kubelet cpu-manager 'static' policy is configured. This decouples performance of application pods from the platform. The new patch Identify-platform-pods-based-on-pod-or-namespace-labels patch is used to identify platform pods using above criteria for Kubernetes 1.25 and later. The hard-coded list of platform namespaces is no longer required. The original hard-coded list is still kept for Kubernetes 1.24 so we can phase in this change. This will also fix the Kubernetes make test fail issue after merging the review https://review.opendev.org/c/starlingx/integ/+/907637 This change also include the missed out patch kubeadm-reduce-UpgradeManifestTimeout.patch for k8s 1.29. Test Plan: PASS: Run all Kubelet, kubeadm, kubectl make tests for affected code. PASS: All affected versions of kubernetes package build successfully. PASS: Create a pod with the platform label. Pod is classified as a platform pod. PASS: Create a pod without the platform label but in a namespace with the platform label. Pod is classified as a platform pod. PASS: Create a pod without the platform label and in a namespace without the platform label. Pod is not classified as a platform pod. PASS: Verify correct cpuset affinity of platform vs application pods after host lock/unlock PASS: Verify kube-system namespace pods are correctly identified as Platform Closes-Bug: 2058042 Story: 2010612 Task: 49910 Change-Id: I0cc05c2e9057b64f9191317e72a1bf4d7b8d0771 Signed-off-by: Boovan Rajendran <boovan.rajendran@windriver.com>
