AWS Image Builder recently introduced lifecycle rules that can help us remove old images from EC2/ECR, and their descriptors on AWS Image Builder side.
CDK added automatic deletion of images in repositories so they can be deleted in CloudFormation easily. We had a custom resource to delete images, but now we can just use
autoDeleteImages
.We still have to clean-up AWS Image Builder image descriptors and AMIs with a custom resource. We do this so removing our construct won't leave anything behind.
Resolves #471
BREAKING CHANGE: CDK 2.110.0 and above is required
