@cboneti any thoughts on this PR? It is very much related to Terraform and i am out of my depth here:)
Thanks in advance.

Looks good to me. I run it on GCP, after setting up proper project info, all works well.

@lsitkiew There was some discussion today about this approach. The general consensus was there should not be a main.tf for full system setup. If will be best to keep all things modular and composable for future use. In the examples dir it would best to have a few components like:

deploy-performance-server
deploy-capacity-server
deploy-clients
full_cluster_setup (that calls the other modules)
run_io500 (that runs after servers/clients are setup) (this can be bash or ansible)

Please try and move the full main.tf steps into the examples directory and refactor it into full_cluster_setup.

Hey folks, I am really sorry for making you wait here. I second what Keith just said, avoiding having a top level main and, instead, having a folder with modules and another with examples. Here are two examples:
https://github.com/terraform-google-modules/terraform-google-vm
https://github.com/SchedMD/slurm-gcp/tree/master/tf

Thanks!

LGTM

I tested this request on my system and it worked fine. It took me a bit to get terraform.tfvars correctly setup for my setup but docs will help. I can help with the docs in a future submission.
