I’ve been trying to install using a GCE image. Then, I’ve tried the command suggested by you:
gcloud compute images create "redash-8-0-0" --source-uri gs://redash-images/redash.8.0.0-b32245-1.tar.gz
I’ve also tried to download the image file, but I’ve got the following issue:
gcloud storage cp gs://redash-images/redash.8.0.0-b32245-1.tar.gz . Completed files 0 | 0B ERROR: (gcloud.storage.cp) HTTPError 403: The billing account for the owning project is disabled in state closed

Then, it keeps trying to install “forever”. Could you help me out with it? Thanks!
