Terraform Configuration Files

Initial Config:

resource "google_compute_forwarding_rule" "linkerd-forwarding-rule" {
  name                  = "linkerd-forwarding-rule"
  backend_service       = "${google_compute_region_backend_service.linkerd-regional-backend-service.self_link}"
  ports                 = ["7007","7019","7021","7029"]
  load_balancing_scheme = "INTERNAL"
}

Changed config:

resource "google_compute_forwarding_rule" "linkerd-forwarding-rule" {
  name                  = "linkerd-forwarding-rule"
  backend_service       = "${google_compute_region_backend_service.linkerd-regional-backend-service.self_link}"
  load_balancing_scheme = "INTERNAL"
}

Debug Output

Initial plan output:

~ module.linkerd-prod.google_compute_forwarding_rule.linkerd-forwarding-rule
    ports.#:          "4" => "0"
    ports.254306664:  "7007" => ""
    ports.3565006559: "7021" => ""
    ports.3668322029: "7029" => ""
    ports.4052448558: "7019" => ""

Apply Ouput:

module.linkerd-prod.google_compute_forwarding_rule.linkerd-forwarding-rule: Modifying... (ID: linkerd-forwarding-rule)
  ports.#:          "4" => "0"
  ports.254306664:  "7007" => ""
  ports.3565006559: "7021" => ""
  ports.3668322029: "7029" => ""
  ports.4052448558: "7019" => ""

Second Plan Output:

~ module.linkerd-prod.google_compute_forwarding_rule.linkerd-forwarding-rule
    ports.#:          "4" => "0"
    ports.254306664:  "7007" => ""
    ports.3565006559: "7021" => ""
    ports.3668322029: "7029" => ""
    ports.4052448558: "7019" => ""

Expected Behavior

Should have removed the optional ports configuration from the forwarding rule and started forwarding all ports as specified in the documentation

Actual Behavior

DIdn't appear to change google forwarding rule at all. Plan still shows desired change as well.

Steps to Reproduce

This will now just fail on apply per #13822
