Packer with GCP

[Mudit]

Hi -

I have to run my packer scripts on a GCP Project. However customer does not allow me to create service account and use the downloaded json for authorization. I have installed Google cloud SDK and configure my project on a local ubuntu machine. However I am unable to run my packer script as authorization fails to the GCP project.

I have run gcloud auth login and complete the steps. How can I connect my packer scripts to the GCP project without using service account?

Regards,
