Build a Docker image with best practices for caching, security, and size optimization.

Steps

  1. Read the existing Dockerfile or generate one if missing.
  2. Analyze the build context:
    • Check .dockerignore exists and excludes unnecessary files.
    • Identify the base image and its size.
    • Map build stages and layer count.
  3. Build the image with build arguments:
    • docker build -t <name>:<tag> --build-arg VERSION=<ver> .
    • Use BuildKit for improved caching: DOCKER_BUILDKIT=1.
    • Add --platform linux/amd64,linux/arm64 for multi-arch if needed.
  4. Verify the build:
    • Check final image size: docker images <name>:<tag>.
    • Run a quick smoke test: docker run --rm <name>:<tag> <health-command>.
    • Scan for vulnerabilities: docker scout cves <name>:<tag>.
  5. Tag appropriately:
    • <name>:latest for development.
    • <name>:<version> for releases.
    • <name>:<git-sha-short> for CI builds.
  6. Report build results and image details.

Format

Docker Build: <name>:<tag>
Base: <base-image>
Size: <size>MB (layers: <N>)
Build time: <duration>

Vulnerabilities: <C>critical, <H>high, <M>medium
Smoke test: <pass/fail>

Push: docker push <registry>/<name>:<tag>

Rules

  • Always use specific base image tags, not latest.
  • Include a .dockerignore to minimize build context.
  • Run as non-root user in the final image.
  • Use multi-stage builds to keep the final image minimal.
  • Add health check instruction (HEALTHCHECK) for production images.
