(aws-eks-v2-alpha): kubectl-based resources may not be successfully created/deleted

[msessa]

Describe the bug

When creating/deleting resources that rely on the kubectl provider (eg. HelmChart, KubernetesManifest) it is possible that the AccessEntry for the kubectl provider could not yet have been created or, in case of a stack deletion, have been deleted before those resources, leaving kubectl without the appropriate permissions.

Expected Behavior

The AccessEntry for the kubectl provider should be included in the KubectlReadyBarrier's dependencies to ensure correct ordering when creating/deleting resources

Current Behavior

The AccessEntry for the kubectl is not explicitly marked as a dependency of the KubectlReadyBarrier resource. Opening the possibility of incorrect order of operation especially during delete.

As an example, these are the CR handler logs of a HelmChart being deleted, which happens after the AccessEntry has already been deleted:

Reproduction Steps

• Create a cluster with kubectl support, and at least one HelmChart or KubernetesManifest resource
• Delete the stack

observe the AccessEntry for kubectl provider being immediately deleted. observe errors in deleting the HelmChart or KubernetesManifest within the logs of the kubectl handler

Hi @msessa,

Thank you for reporting this issue and for already providing a comprehensive fix in PR #34898!

Issue Confirmed:
You've correctly identified a dependency ordering problem in the EKS v2 alpha implementation. The AccessEntry for the kubectl provider was not being added as a dependency to the KubectlReadyBarrier, causing authentication failures during stack deletion.

Your Fix is Spot On:
The solution in PR #34898 correctly adds the missing dependency:

this._kubectlReadyBarrier.node.addDependency(this._clusterAdminAccess);

This ensures that kubectl-based resources are always deleted before their required AccessEntry, preventing the "server has asked for client to provide credentials" errors you observed.

Impact:
This fix will significantly improve the reliability of EKS v2 alpha cluster teardown operations, especially for clusters using HelmChart and KubernetesManifest resources.

The PR looks well-structured with appropriate test updates. Thank you for both identifying the issue and providing a clean, targeted solution!
