What problem does it solve?

It helps teams fix slow, insecure, oversized, and unreliable Docker builds by applying production-grade containerization best practices and validation workflows.

Core Features & Use Cases

• Dockerfile optimization & multi-stage builds: Improves build caching, reduces image size, and structures artifacts for clean production runtimes.
• Container security hardening: Guides non-root execution, safer base image usage, and secret-handling patterns to lower attack surface.
• Compose orchestration & validation: Validates Docker/Compose configurations and runtime behavior using health checks and repeatable build/run checks.
