Debug Output

Shouldn't be needed

Panic Output

None

Steps to Reproduce

1. terraform plan

Expected Behavior

Expected a successful plan, based on the content of https://registry.terraform.io/providers/hashicorp/kubernetes/latest/docs/resources/service which lists the load_balancer_ingress attribute. However, according to the changelog of 2.0.0 of the TF provider, it appears this information has moved. According to the code in https://github.com/hashicorp/terraform-provider-kubernetes/pull/1071 it looks like it might now be found under status.*. load_balancer.*.ingress.*.hostname, although that is just a guess.

It seems like the documentation needs to be updated.

Actual Behavior

Error: Unsupported attribute

  on vpce_with_tls_termination_at_nlb.tf line 83, in data "aws_lb" "traefik_vpce_nlb":
  83:   name = split("-", split(".", kubernetes_service.traefik_vpce_ingress.load_balancer_ingress.0.hostname).0).0

This object has no argument, nested block, or exported attribute named
"load_balancer_ingress".

It is documented in the upgrade guide.

The change is as you assumed, e.g.:

 output "kubernetes_load_balancer_ip" {
   -  value = data.kubernetes_service.load_balancer.load_balancer_ingress[0].ip
   +  value = data.kubernetes_service.load_balancer.status[0].load_balancer[0].ingress[0].ip
 }

Thanks for this bug report! Your guess is correct. The information can now be found under status.0.load_balancer.0.ingress.0.ip and status.0.load_balancer.0.ingress.0.hostname. The docs will have to be updated to reflect this.
