Description

Add support for GKE Workload Identity. This would involve a new field/configuration block on google_container_cluster to enable the workload identity feature, as well as updating the list of allowed values in the workload_metadata_config block which is part of node_config.

New or Affected Resource(s)

• google_container_cluster
• google_container_node_pool

Potential Terraform Configuration

resource "google_container_cluster" "my-cluster" {
  ...
  enable_workload_identity = "true"
  ...
}

resource "google_container_node_pool" "my-node-pool" {
  ...
  node_config{
    workload_metadata_config {
      node_metadata = "GKE_METADATA_SERVER"
    }
  }
  ...
