Can it help with Docker security hardening?

Yes, it implements non-root user configurations, manages secrets securely without environment variables, and applies resource limits and capability restrictions to minimize the attack surface.

How does this skill optimize Docker image size?

It utilizes multi-stage builds, selective artifact copying, and minimal base images like Alpine or Distroless to remove unnecessary build tools and dependencies from the final production image.

Does it support complex Docker Compose setups?

Absolutely. It provides production-ready templates for service dependency management, health checks, named volumes, and isolated network configurations for multi-container applications.

Is it suitable for improving CI/CD performance?

Yes, it focuses on layer caching optimization and build context management, which directly reduces build times and improves reliability in automated CI/CD environments.
