cluster maintenance window must be timestring

[mikebou]

TL;DR

Support and the documentation both agree that the end date for the var.maintenance_end_time should allow a value of "" however using a value of "" generates the following error.

Error: "maintenance_policy.0.daily_maintenance_window.0.start_time" ("2024-06-22T22:00:00Z") must be in the format HH:mm (RFC3339) with module.gke_pe_dev.google_container_cluster.primary on .terraform/modules/gke_pe_dev/modules/beta-private-cluster/cluster.tf line 375, in resource "google_container_cluster" "primary":

Expected behavior

using source = "terraform-google-modules/kubernetes-engine/google//modules/beta-private-cluster" version = "~> 33.0"

setting a maintenance window of maintenance_recurrence = "FREQ=WEEKLY;BYDAY=SA" maintenance_start_time = "2024-06-22T22:00:00Z" maintenance_end_time = ""

should pass terraform plan and create a weekly maintenance window on every Saturday night starting Jun 22 of last year.

Im not sure this is a module issue, as the error is coming from the provider itself
