Up & Running — Docker:

: Best practices include avoiding running containers as root and using specialized tools to scan images for secrets or vulnerabilities. Advanced Orchestration & Ecosystem

: Learn to use multi-stage builds to create the smallest possible production-ready containers by separating build-time dependencies from the final runtime.

: Containers are intended to be ephemeral—nothing in the application's environment should live longer than the application itself. Docker: Up & Running

: For production stability, you must set memory and CPU limits to prevent a single container from exhausting host resources and crashing the system.

Docker has fundamentally changed how we build and ship software by providing a layer of isolation that reduces the "human communication burden" between developers and operations. : Best practices include avoiding running containers as

The book's central architectural philosophy revolves around .

Moving beyond a single machine requires a shift in mindset toward orchestration: docker compose up - Docker Docs : For production stability, you must set memory

: When you deploy, you throw away the old environment entirely. This prevents "configuration drift" where apps accidentally rely on artifacts or manual "hotfixes" left behind by previous releases. Building for Production
