What problem does it solve?
This Skill prevents bloated, insecure, and flaky Docker images by guiding you to build production-grade containers using multi-stage builds, minimal runtime bases, cache-efficient BuildKit practices, and automated vulnerability scanning.
Core Features & Use Cases
- Multi-stage Dockerfile optimization: Produces smaller images by separating dependency install, build, and runtime stages, often using distroless or scratch.
- BuildKit performance + reproducibility: Uses cache mounts and appropriate syntax directives to speed up builds while keeping lockfile-driven installs.
- Security hardening and scanning: Enforces non-root execution, healthchecks, and recommends CVE scanning with Docker Scout and/or Trivy.
- Local dev with Docker Compose: Sets up compose watch for hot reload and service health gating for smoother development.
- Multi-arch build support: Guides use of buildx for cross-platform images and platform-specific considerations.
Quick Start
Ask the agent: "Create a production-ready Dockerfile for my Node.js app using multi-stage builds, a distroless runtime, non-root, a healthcheck, and scan the resulting image for HIGH and CRITICAL CVEs."
