Issue

#29800

Reason for this change

Allow using recommended kernel version instead of 4.14 which is marked as EOL Jan 2024, by opting in for the new kernel.

We recommend that you use an AMI with Linux kernel 5.10 because Linux kernel 4.14 reached end-of-life on January 10, 2024.

Description of changes

  • Deprecate the existing amazonLinux2 in favor of a new amazonLinux2WithKernel510.

Description of how you validated changes

Unit and integration tests.

Thanks 👍
I left some suggestions for adjustments.
Also, does the recommended here refer to the kernel version? 🤔
If so, we should remove it when kernel is specified.

I am not sure what recommended refers to, but since it precedes image_id, I thought it might be related to hardware type.

Both of the following commands return a valid AMI from SSM

aws ssm get-parameters --names /aws/service/ecs/optimized-ami/amazon-linux-2/kernel-5.10/gpu/recommended/image_id

and

aws ssm get-parameters --names /aws/service/ecs/optimized-ami/amazon-linux-2/kernel-5.10/recommended/image_id

Discussed offline, this should not be undeprecated...sorry about that, I was wrong. This entire props should be deprecated and replaced with the linked EcsOptimizedImage instead.

@comcalvi I replied to your comment here. Can you have a look?

This entire props should be deprecated and replaced with the linked EcsOptimizedImage instead.

EcsOptimizedImage is a class and its private constructor is still using the deprecated EcsOptimizedAmiProps. There are no other Props interfaces for EcsOptimizedImage constructor.

Is it time to remove @deprecated already?

It looks like we deprecated the props and decided to create a bunch of factory methods that take an Options instead of props. I think your original solution was actually correct; leave these as deprecated (since they should be marked internal, and if we remove the deprecation we'll never remember to fix this) and just add the new property.

@TheRealAmazonKendra is correct about this, in principle, since a deprecated marker implies that these props have been directly replaced by something else. That is not what is going on here. Instead, these props are supposed to be hidden away behind a set of factory methods. So, even if we had not missed these when we did v2, the optimal would still be what you've done here; add kernel to these props.

Sorry for the churn on this one, please leave the @deprecated and add the new property to those deprecated props.

@comcalvi Thanks for the update 🙏
I am not entirely confident I am following what has been the final decision regarding how this change should be incorporated but I tried to revert to a previous state in this branch history; namely (c107fe0).

Please let me know if I misunderstood your last comment. Thanks again
