Skaffold and kubectl version

[jsok]

Hi there,

The kubectl version (v1.20.0) bundled in the skaffold container image (gcr.io/k8s-skaffold/skaffold:v1.37.2-lts) used by Cloud Deploy is very old, I'm deploying to GKE v1.22+ clusters.

I'm attempting to use skaffold's kubectl flags:

    deploy:
      kubectl:
        flags:
          apply:
            - --prune

I realise --prune is an alpha option, however it's failing due to version skew issues e.g.:

error: error retrieving RESTMappings to prune: invalid resource extensions/v1beta1, Kind=Ingress, Namespaced=true: no matches for kind "Ingress" in version "extensions/v1beta1"

 Is there some way to have Cloud Deploy run with a kubectl version that's newer or ideally matches the target GKE cluster?

Thanks in advance!
