Expose the private_cluster_config attributes as outputs

[imnotyourbrobro]

TL;DR

For the private-cluster module, it would be nice to have the private_cluster_config exposed as an output so we can derive the private_endpoint IP address. As of now, only the endpoint attribute is exposed as an output.

Terraform Resources

This is the module in question: https://github.com/terraform-google-modules/terraform-google-kubernetes-engine/tree/main/modules/private-cluster

Outputs are defined here: https://github.com/terraform-google-modules/terraform-google-kubernetes-engine/blob/main/modules/private-cluster/outputs.tf

Detailed design

These could be used:


output "private_cluster_config" {
  description = "Private cluster config"
  value       = google_container_cluster.primary.private_cluster_config
}

Additional information

Someone had recommended a workaround in #502 (comment) with a data source. This can be done that way, but it'd be much nicer if the module exposed it as-is so that this data source doesn't need to be used for inferring the private_endpoint
