This algorithm change is Simplex only.
The algorithm for multi-version upgrade for k8s is:
- system kube-upgrade-start <final version>
- system kube-upgrade-download-images
- system kube-upgrade-networking
- system kube-host-cordon controller-0 (future)
- loop <v> from current version to final version
- system kube-host-upgrade controller-0 control-plane <v>
- system kube-host-upgrade controller-0 kubelet <v>
- system kube-host-uncordon controller-0 (future)
- system kube-upgrade-complete
- system kube-upgrade-delete
This change does the following additional cleanup:
- remove patch-apply intermediate steps during kube-upgrade
- remove all patching mixings from kube upgrade strategy
Test Plan:
PASS: (multi-upgrade) AIO-SX kube upgrade orchestration
v1.21.8 to v1.24.4
PASS: (single upgrade) AIO-DX kube-upgrade orchestration
v1.21.8 to v1.22.5
