Can not build image with packer about cloud-builders-community

[swelljoe]

I see the same problem. I can run packer locally on my machine to build the image if I removed the impersonate_service_account option from build.pkr.hcl, which presumably is necessary for building in Google Cloud.

I also tried upgrading to the latest packer image version (1.1.0) which made no differences. I can't find any mention of this problem on the Hashicorp forum or ticket tracker, so I assume it's some kind of change on the Google backend. I can't figure out from the source, thus far, where the "scopes" are supposed to come from. I tried using the scopes option in build.pkr.hcl, but the docs are pretty sparse and while I didn't get an error, it didn't make a difference in the error; I don't know if that's the scopes this error is about.

Can you please confirm that Cloud Build Service Account being used have proper permissions setup to create a VM image (docs). You will also need to add roles/iam.serviceAccountUser as well (example)

Problem you have encountered:

I try to build gce image with packer, but it does not work. I encounter an error about impersonate: scopes must be provided. The detail is following

What you expected to happen:

Get a new gce image artifact.

Steps to reproduce:

1. git clone https://github.com/GoogleCloudPlatform/cloud-builders-community.git
2. go into the dir packer of the repo, build a packer image with cloud build

gcloud builds submit .

3. go into the dir packer/examples/gce of the repo
4. following the README.md to configuring service account for packer
5. modify the packer variables variables.pkrvars.hcl
6. run build with script

gcloud builds submit --config=cloudbuild.yaml .

Other information (workarounds you have tried, documentation consulted, etc):

It works well until November 23rd with the same steps above.

I got the same issue - after done Service Account setup following the README.md, I've two SA

• serviceAccount:packer@${PROJECT_ID}.iam.gserviceaccount.com -> has the necessary GCE permissions
• ${PROJECT_NUMBER}@cloudbuild.gserviceaccount.com -> has the right to impersonate Packer Service Account

But Google is still showing me "impersonate: scopes must be provided", and I don't know the reason yet after a long search from Google search...

Still have the same issue

Found a similar issue against the googlecompute Packer plugin:

hashicorp/packer-plugin-googlecompute#204

Downgrading to version 1.1.3 of the plugin worked around the issue for me as well.
