Which module is preferred for Karpenter installation?

[asychev]

This module supports Karpenter provisioning, same as terraform-aws-eks (via submodule).
Are there particular reasons to have this duplication? What is the preferred way?

[bryantbiggs]

The EKS module does not provision Karpenter - it only provides the necessary AWS infrastructure resources for Karpenter

[asychev]

Yes, but they still overlap. Do I understand correctly this module not yet support v20.x EKS clusters created with authentication_mode = "API"?

Correct - that would be something incorporated into v2.0 of this module
