You can use ECR lifecycle policy, which has been recently added by AWS https://docs.aws.amazon.com/AmazonECR/latest/userguide/LifecyclePolicies.html

Here's an example of a policy to only keep one untagged image and expire all others ECR policy rule

You can try using aws cli - set the correct AWS REGION where your ecr repositories exists.

AWSREGION=us-west-2 && ecr describe-repositories --region=$AWSREGION --output text | awk '$5{print $5}' | sed -n  's/.*repository\/\(.*\)/\1/p' | while read line; do aws ecr list-images --region=$AWSREGION --repository-name "$line" --filter tagStatus=UNTAGGED --query 'imageIds[*]' --output text | while read imageId; do aws ecr batch-delete-image  --region=$AWSREGION --repository-name "$line" --image-ids imageDigest=$imageId; done; done

This command will delete all the untagged images recursively. Hope this solves your problem.

What happens is when you publish an image:tag the tag will be removed from the previous image.

You can run a CLI command to identify the images that are untagged and pipe the output to the command to delete those.

You can also use lifecycle policies.

Refer the link below. I haven't tested this myself.
