Check name	Status	Explanation	Resolution
Title Check	❓ Inconclusive	The title “Update main.tf” is overly generic and does not communicate the specific change made in the pull request, namely altering the kubernetes.io/role/elb tag value from a number to a string within the VPC module. Because it lacks descriptive context about the main modification, it fails to give reviewers a clear understanding of the purpose of this patch.	Consider revising the title to succinctly reflect the primary change, for example: “Change VPC module’s kubernetes.io/role/elb tag value from number to string.”

Poem

I nudge a tag from 1 to "1",
A tiny hop—then I am done.
Subnets smile, ELBs agree,
Types aligned in harmony.
Thump-thump goes my review drum—
Ship it quick, more carrots come! 🥕🐇

84-96: Remove addon_version pins from aws_eks_addon resources
Pinned versions (ebs-csi v1.39.0-eksbuild.1, kube-proxy v1.31.3-eksbuild.2, vpc-cni v1.19.2-eksbuild.1, coredns v1.11.4-eksbuild.2) may be incompatible with Kubernetes 1.32; omit addon_version to let EKS select the recommended version—or if you must pin, verify via aws eks describe-addon-versions.

AL2 is supported through Kubernetes 1.32 with EKS AMI updates ending November 26, 2025. Consider planning a move to AL2023 or Bottlerocket for future upgrades.

33-34: Good fix: tag value should be a string.

AWS tags are strings; the AWS Load Balancer Controller expects public subnets to have kubernetes.io/role/elb with value "1". Your change aligns with the documented requirement.
See: AWS re:Post and AWS LBC docs. (repost.aws, kubernetes-sigs.github.io)

⚠️ Potential issue

Cluster-name tag mismatch will break subnet auto-discovery.

The subnet tag uses "your_cluster_name" but the EKS cluster_name is "mycluster". For AWS LBC auto-discovery, the kubernetes.io/cluster/ tag must match the actual cluster name.

Proposed change (keep the name in one place to avoid drift):

+locals {
+  cluster_name = "mycluster"
+}
...
-  cluster_name    = "mycluster"
+  cluster_name    = local.cluster_name
...
-    "kubernetes.io/cluster/your_cluster_name" = "shared"
+    "kubernetes.io/cluster/${local.cluster_name}" = "shared"
