Default Cluster Version in EKS

Hello,

Let me suggest a way for you to know default version. You can use the flag --dry-run with eksctl which make calls to EKS API. Same option isn't available in AWS CLI EKS as of now.

eksctl create cluster --name development --dry-run | grep version
  version: "1.22"

The community releases new Kubernetes minor versions, such as 1.23 but they don't automatically immediately become the default version on EKS.

1.22 (Amazon EKS release date April 4, 2022) is the default version because it has endured more support duration than 1.23 (Amazon EKS release date August 11, 2022).
