Our build is currently failing with

ERRO[0000] Error while retrieving image from cache: marketplace.gcr.io/google/debian9 GET https://marketplace.gcr.io/v2/google/debian9/manifests/latest: UNAUTHORIZED: You don't have the needed permissions to perform this operation, and you may have invalid credentials. To authenticate your request, follow the steps in: https://cloud.google.com/container-registry/docs/advanced-authentication

Based on GoogleContainerTools/kaniko#659, one solution is to switch to an endpoint that doesn't require authentication. This endpoint that I'm using comes from the docs for managed images: https://github.com/GoogleContainerTools/base-images-docker/tree/master/debian
