It all looks good to me, assuming the tests pass (still running as I write this).

@heyealex I would love if you could take a look at the changes in community/modules/scheduler/schedmd-slurm-gcp-v5-hybrid/ main.tf and variables.tf. Thanks.

I ran a test with our GCP demo (documented here) and it all worked as expected.

I also looked over the code and everything looks correct to me. Thank you!
