What is degraded state in EKS ?

Question

I read this page https://docs.aws.amazon.com/eks/latest/userguide/enable-kms.html, it says that 
> If you enable secrets encryption for an existing cluster and the KMS key that you use is ever deleted, then there's no way to recover the cluster. If you delete the KMS key, you permanently put the cluster in a degraded state.

My question is what does degraded state means ?

Answer

I think it means that the EKS cluster can't perform all of its functions, such as creating new Kubernetes secrets and running pods. You can't create a new Kubernetes secret and encrypt it, and the pods running inside the cluster can't decrypt the Kubernetes secrets as the existing KMS key is deleted.

So, you would have to create a new EKS cluster with a new KMS key.
