Explanation
Amazon ECR lifecycle policies are a built-in, managed feature that can automatically expire images based on rules such as image age and can enforce retaining a minimum number of images (for example, keeping the most recent N images). This meets the automatic cleanup and minimum-retention requirements without custom code or scheduled jobs, resulting in the least operational overhead.
