Can I automatically enable APIs when using GCP cloud with terraform?

Question

I am very new to GCP with terraform and I want to deploy all my modules using centralized tools.

Is there any way to remove the step of enabling google API's every time so that deployment is not interrupted?

Answer 1

There is a Terraform resource definition called "google_project_service" that allows one to enable a service (API). This is documented at google_project_service.

An example of usage appears to be:

resource "google_project_service" "project" {
  project = "your-project-id"
  service = "iam.googleapis.com"
}

Answer 2

Yes , you can use google_project_service resource to enable one API at a time. You can use count or other loop methods to enable multiple APIs. You would need project editor/owner role to do this.

# Enable services in newly created GCP Project.
resource "google_project_service" "gcp_services" {
  count   = length(var.gcp_service_list)
  project = google_project.demo_project.project_id
  service = var.gcp_service_list[count.index]

  disable_dependent_services = true
}

You can find the complete example here.

Answer 3

instead of using count as suggested by @pradeep you may also loop over the services in question:

variable "gcp_service_list" {
  description ="The list of apis necessary for the project"
  type = list(string)
  default = [
    "cloudresourcemanager.googleapis.com",
    "serviceusage.googleapis.com"
  ]
}

resource "google_project_service" "gcp_services" {
  for_each = toset(var.gcp_service_list)
  project = "your-project-id"
  service = each.key
}
