Default Cluster Version in EKS

Question

Hi.

Is there any way to know the default version of the Cluster that will be set in EKS via SDK or API other than the aws console?

Why is the default version of Cluster in EKS 1.22 instead of 1.23?
Are there any rules by which the default version is determined?

Thanks!

Accepted Answer

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).

Refer to this [doc](https://docs.aws.amazon.com/eks/latest/userguide/kubernetes-versions.html#kubernetes-release-calendar) to know more about how AWS plan their Kubernetes releases
