-There are some important considerations for the Kubernetes package repositories:
-
-- The Kubernetes package repositories contain packages beginning with those
-  Kubernetes versions that were still under support when the community took
-  over the package builds. This means that anything before v1.24.0 will only be
-  available in the Google-hosted repository.
-- There's a dedicated package repository for each Kubernetes minor version.
-  When upgrading to a different minor release, you must bear in mind that
