Use Image Scanning for AWS ECR


Amazon just announced that ECR now has the image scanning capability. It is a good News if you use ECR as your Docker image registry, as you just can consume it for free!

A good use case is to add it into your CI pipeline for image scanning. A quick example of scanning the Docker Image atlassian/jira-software:8.3.

Parse the findingSeverityCounts of the scanning results, and mark the build as failed if it has any Medium to High Severity.

    "findingSeverityCounts": {
        "INFORMATIONAL": 10,
        "LOW": 23,
        "MEDIUM": 16
    }

Sample scanning reports:

        "findings": [
