Scan an image uploaded to ECR and fail if vulnerabilities are found.
As of version 3.0.0, only enhanced scanning is supported. Basic scanning support has been removed from this version onwards. If you still need basic scanning support, please use version ^2.0.1. To enable enhanced scanning, check out the AWS documentation.

To use this GitHub action in your workflow, your ECR role/user will need to have the following permissions:
ecr:DescribeImageScanFindingsecr:StartImageScan(unless scan on push is enabled)
This example builds a docker image, uploads it to AWS ECR, then scans it for vulnerabilities.
on:
# Trigger on any GitHub release.
# If you want to trigger on tag creation, use `create`. However, this also
# fires for branch creation events which will break this example workflow.

- run: echo "${{ steps.docker-scan.outputs.total }} total vulnerabilities."This action is implemented as a Docker rather than a Javascript action because that would require committing node_modules to the repository.
You can test the action by running it locally like so:
docker build -t ecr-scan-image:dev .
docker run -t \
-e INPUT_REPOSITORY=myorg/myapp \
-e INPUT_TAG=test-tag \
-e INPUT_FAIL_THRESHOLD=critical \
-e AWS_ACCESS_KEY_ID=xxx \
-e AWS_SECRET_ACCESS_KEY=xxx \
-e AWS_REGION=xxx \
