aws-eks: addAutoScalingGroupCapacity lacks support for Amazon Linux 2023

[isker]

Describe the feature

addAutoScalingGroupCapacity allows the user to select a MachineImageType, but this only includes AL2 or Bottlerocket. AL2023 is missing.

https://github.com/aws/aws-cdk/blob/v2.139.0/packages/aws-cdk-lib/aws-eks/lib/cluster.ts#L2468-L2480

Use Case

I want to use a newer kernel than is available in AL2 on my EKS ASGs.

Proposed Solution

No response

Other Information

AL2023 support has been added for managed node groups but not for ASGs. See #29546 #29334. cc @pahud as you've handled those issues.

Acknowledgements

• I may be able to implement this feature request
• This feature might incur a breaking change

CDK version used

Environment details (OS name and version, etc.)

N/A

Yes we could have a PR for that. But I am wondering why you opt in addAutoScalingGroupCapacity rather than addNodeGroupCapacity? Is there any feature not supported in the managed nodegroups?

[pahud]

@isker Is it because Nodegroup currently does not support tagging ASG? This would be a huge tradeoff. In CDK, you still can create a managed nodegroup and a custom resource to tag the ASG behind the nodegroup. Would this be something you expect?

check #29280 (comment) and #29280 (comment)

Feel free to chat with me on cdk.dev if you need.

Thanks for that information. I'll take a look.

CDK should support AL2023 on EKS ASGs.
