Secure Container Image Builds with GitHub Actions

A minimal GitHub Actions approach to reproducible builds, provenance, and vulnerability checks for container images.

GitHub Actions can produce trustworthy images when the pipeline is explicit about provenance.

Baseline workflow #

  1. Build with pinned actions and deterministic build arguments.
  2. Generate an SBOM for every pushed image digest.
  3. Run vulnerability scanning as a required check.
  4. Sign images using keyless OIDC signing.

Team-level win #

Once this pattern is in place, deployment approvals can focus on actual risk instead of guessing whether an image is trustworthy.
