Hi everybody, I found the document for upgrading K8s version here at https://docs.starlingx.io/configuration/k8s_upgrade.html#build-patches-manua... However, I got stuck when the document does not clearly show how to build K8s upgrade patches. Since after installing R4 version, I could not found any folders/fille in that document for building such as: /stx/downloads, sysinv/sysinv/sysinv/sysinv/common/kubernetes.py, /stx/integ, ... Could anybody tell me how to get it? Or are there any other documents?
