Please expose resource_policies as a variable for the instance_template

[ryboe]

TL;DR

The google_compute_instance_template resource supports adding a resource_policy, but it's not exposed as a variable in this module. I would like to set a policy that the instance is restarted weekly. Please add something like this to variables.tf so we can set resource policies.

variable "resource_policies" {
  type = list(string)
}

Terraform Resources

1. google_compute_instance_template.resource_policies
2. google_compute_resource_policy

Detailed design

module "instance_template" {
  source  = "terraform-google-modules/vm/google//modules/instance_template"
  ...
  resource_policies = [ google_compute_resource_policy.sunday_night_restart.self_link ]
}

resource "google_compute_resource_policy" "sunday_night_restart" {
  name   = "sunday-night-restart"
  region = "us-central1"
  description = "Sunday night restart"
  instance_schedule_policy {
    vm_start_schedule {
      schedule = "30 23 * * 7"
    }
    vm_stop_schedule {
      schedule = "0 23 * * 7"
    }
    time_zone = "US/Central"
  }
}

In addition to the use case noted above, resource policies can also be used to specify "placement" in Google Cloud. In large scale HPC workloads, the placement policy can specify the maximum network "distance" allowed between VMs to minimize network latency of workloads that are coupled across VMs.
