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!

If you're running the image directly to a GKE cluster, the image will be placed in the image source parameter under the workload YAML, in that case it would be better for you to contact the skaffold team to review further development options.

Thank you for the inquiry! Skaffold version 1.39.x LTS will include an updated kubectl to v1.22.0. As part of Google Cloud Deploy's next Skaffold version upgrade, the kubectl version will be updated as well as.

The update to Skaffold 1.39.x LTS has completed, and is now the Cloud Deploy default:
