# This workflow uses actions that are not certified by GitHub.
# They are provided by a third-party and are governed by
# separate terms of service, privacy policy, and support
# documentation.

# This workflow checks out code, builds an image, performs a container image
# vulnerability scan with Trivy tool, and integrates the results with GitHub Advanced Security
# code scanning feature.
