Multiple versions of kubernetes are required to support upgrade. This adds staged version of kubernetes 1.21.3, built with a specific version of golang. All subpackage versions are included in the iso image without collisions. The following patches are ported to specific kubernetes version: kubelet-cpumanager-disable-CFS-quota-throttling-for-.patch kubelet-cpumanager-keep-normal-containers-off-reserv.patch kubelet-cpumanager-infrastructure-pods-use-system-re.patch kubelet-cpumanager-introduce-concept-of-isolated-CPU.patch kubeadm-create-platform-pods-with-zero-CPU-resources.patch enable-support-for-kubernetes-to-ignore-isolcpus.patch The following changes were made for 1.21.3: - following upstream commit was reverted: Revert-use-subpath-for-coredns-only-for-default-repo.patch - kubelet-cpumanager-disable-CFS-quota-throttling-for-.patch was refactored due to new internal_container_lifecycle framework We leverage the same mechanism to set Linux resources as: cpu manager: specify the container CPU set during the creation (commit 38dc7509f862f081828e7d9167107b8c6e98ea23). - kubelet-cpumanager-introduce-concept-of-isolated-CPU.patch was refactored due to upstream API change: node: podresources: make GetDevices() consistent (commit ad68f9588c72d6477b5a290c548a9031063ac659). The routine podIsolCPUs() was refactored in 1.21.3 since the API p.deviceManager.GetDevices() is returning multiple devices with a device per cpu. The resultant cpuset needs to be the aggregate.

The spec file used here was from the kubernetes 1.10.0 src rpm. The orig file is included to help show modifications made to that spec file, to help understand which changes were needed and to assist with future upversioning.
The contrib tarball does not have the same versioning as kubernetes and there is little activity in that repo.
The version for the contrib tarball is arbitrary.
