**Tell us about your request**
Extra filters for enhanced image scanning to limit scanned images by tag.

**Which service(s) is this request for?**
ECR

**Tell us about the problem you're trying to solve. What are you trying to do, and why is it hard?**
In [https://docs.aws.amazon.com/AmazonECR/latest/userguide/image-scanning.html ](https://docs.aws.amazon.com/AmazonECR/latest/userguide/image-scanning.html) you describe how we can use filters with enhanced scanning to limit the repositories that are scanned.

Could this be extended to allow us to filter specific image tags? For example, if we specify a tag filter of `develop-*` then only images pushed to ECR with a tag starting `develop-` will be scanned?

**Are you currently working around this issue?**
Am currently unable to work around this issue and all images for all tags are being scanned.

**Additional context**
None

**Attachments**
None

Start with the AWS ECR enhanced image scanning documentation linked in the issue and review how repository filters currently work. Define what tag patterns such as `develop-*` should match and what the completed feature should do for images with other tags; the issue names no repository files or tests.
