やったこと

• found a potential solution to:

  my code has a problem where I pass in Kind as Resource to the GVR in https://github.com/kubernetes/autoscaler/pull/5419 but that won't work

added code to pluck resources from crd's spec.names.plural field https://github.com/kubernetes/autoscaler/pull/5419/commits/790ef46cac80f233b2d2f4d177c1bce5d106a760

• removed generic lister factory for now (adding a factory is making things a little complicated): https://github.com/kubernetes/autoscaler/pull/5419/commits/dc4d5eff4414a29904ec5d589292b0a02d79b1e5

TODO

• check the Kanban

Problem

• unit tests in utils/drain_test.go are still failing because the scheme is empty and type meta for the objects is empty because of which scheme can't be set in the code either

K8s Service Account for cluster-autoscaler has the right annotation and the GKE Service Account has the right permissions too.
