Amazon EKS Kubernetes upgrade

[FuhuXia]

Received AWS Email notification requesting existing Amazon EKS Kubernetes 1.21 upgrade due to end of extended support of 1.21. If no action taken, they will be auto upgraded to 1.22 after July 15, 2024.

Sketch

Manually upgrade EKS Kubernetes from 1.21 to the latest available version. We have two EKS Kubernetes clusters, one in ssb-development and one in ssb-production, both on 1.21.

Upgraded EKS Kubernetes cluster on ssb-development to 1.25
Upgraded EKS Kubernetes cluster on ssb-production to 1.23. When tried to upgrade it further, it complains

Nodegroups k8s-690fc34f7d51eacf-20220822174235688200000012
must be updated to match cluster version 1.23 before updating cluster version

Did not see any upgrade option on the AWS console to upgrade the Nodegroups. Maybe we need to use cli. Will deal with it when 1.23 is facing end of extended support.
