Thanks so much, Ross. I'm going to keep plugging away as I think of new things this weekend, in the hopes that I don't need to take up your time Monday and can cancel our meeting. My everlasting gratitude either way.
Does the GCP Compute-Engine VM need to be in the same project that got created by GAM? I was using a pre-existing VM from another project, and when I try:
gcloud config set project gam-project-xxx-yyy-zzz
I get the following error:
WARNING: You do not appear to have access to project [gam-project-xxx-yyy-zzz] or it does not exist.
I'm going to try and see if I can find a way to switch the gcloud session in the VM to the GAM created project without moving the VM.
I had already changed the service account associated with the VM to match the one created by GAM, BTW.
I am also going to try installing GAM directly in cloud shell, as my further searches in this group mentioned that.
Thanks again and best regards,
Claudio
