With Kubernetes 1.27, we (SIG Auth) are moving Key Management Service (KMS) v2 API to beta. What is KMS?

KMS provides an interface for a provider to utilize a key stored in an external key service to perform this encryption. KMS v1 has been a feature of Kubernetes since version 1.10, and is currently in beta as of version v1.
