Cannot pass a label to eks_managed_node_group

[gagbo]

Description

It might be a duplicate of #2976

My eks_managed_node_group is :

    infra = {
      name           = "infrastructure"
      instance_types = ["t3.medium"]
      min_size       = 1
      desired_size   = 1
      max_size       = 1
      ami_type = "AL2023_x86_64_STANDARD"
      labels = {
        "fp.io/node-type" = "infrastructure"
      }
      tags = {
        "FP.Environment" = "demo"
      }
    }

But when I check the associated node in kubernetes using describe I don’t see my label

• ✋ I have searched the open/closed issues and my issue is kind of listed: Not able to pass lable to node #2976 but is stale

⚠️ Note

I will edit to try to fit this node group in one of the examples, but given #2976 I suppose there’s something obvious I missed in the documentation?

Reproduction Code

Just replacing the label from GithubOrg to "fp.io/node-type" in the eks example for AL2023 should be enough

Steps to reproduce the behavior:

Init and apply an aws_eks_cluster with an eks_managed_node_groups value containing:

    infra = {
      name           = "infrastructure"
      instance_types = ["t3.medium"]
      min_size       = 1
      desired_size   = 1
      max_size       = 1
      ami_type = "AL2023_x86_64_STANDARD"
      labels = {
        "fp.io/node-type" = "infrastructure"
      }
      tags = {
        "FP.Environment" = "demo"
      }
    }

Expected behavior

Have the label fp.io/node-type on all nodes in the node group

Actual behavior

The label does not appear

Terminal Output Screenshot(s)

See above the list of labels in kubectl describe node after the apply

Additional context

There’s a mention in the documentation about being compatible with EKS API, but I couldn’t find this documentation anywhere. And I suppose I should not need to mess with the bootstrap scripts/user data to add a label, so I suppose I missed something
