(aws-cdk-lib/aws-ecr): LifecycleRule not working properly (?)

[ValchanOficial]

Describe the bug

maxImageAge is deleting all images, including images to be retained
I want to keep the latest 2 images from each tag and from each package
There is a way to say which package is when I create a new ecr.Repository?

Expected Behavior

keep images from maxImageCount

If I have 3 packages - Shoud be kept 2 images from each one - Total: 6
And so on

Current Behavior

All images are being deleted

Reproduction Steps

Code:

....
const lifecycleRules = [
  { tagPrefixList: ['alpha'],  maxImageCount: 2 }
  { tagPrefixList: ['beta'],  maxImageCount: 2 }
  { maxImageAge: Duration.days(30) } // when add this line, after 30 days, all images are deleted
]

const ecrExample = new ecr.Repository(scope, 'Example', {
  imageScanOnPush: true,
  imageTagMutability: ecr.TagMutability.IMMUTABLE,
  lifecycleRules,
  repositoryName: 'Example',
})
...

@ValchanOficial I don't think, it is an issue, if you give maxImageAge: 30 then it will delete all images after 30 days, please remove your rule { maxImageAge: Duration.days(30) }.

But I don't want to keep old images, only the latest 2 images

[ayush-shah-1501]

Your first two rules will contain only 2 latest images for each tags.
{ tagPrefixList: ['alpha'], maxImageCount: 2 }
{ tagPrefixList: ['beta'], maxImageCount: 2 }

you do not required
{ maxImageAge: Duration.days(30) } rule.

Thank you @ayush-shah-1501 for the feedback.

Your first two rules will contain only 2 latest images for each tags. { tagPrefixList: ['alpha'], maxImageCount: 2 } { tagPrefixList: ['beta'], maxImageCount: 2 }

you do not required { maxImageAge: Duration.days(30) } rule.

Thank you, I will try this
