ECR image scan on push is not enabled

Description

Amazon ECR is a fully managed container registry used to store, manage and deploy container images. ECR Image Scanning assesses and identifies operating system vulnerabilities. Using automated image scans you can ensure container image vulnerabilities are found before getting pushed to production. ECR APIs notify if vulnerabilities were found when a scan completes.

Fix - Runtime
