Mastering Docker, Linux, and Containerization for JS & AI Apps","state","published","contactAuthorMethod","email","aboutText","

Stop running your applications directly on \"localhost\" and step into production-grade systems architecture.

For modern developers, building a local prototype is only the first step. The true challenge lies in deployment. When your application scales to include JavaScript frontends, Node.js backend APIs, Python AI inference engines, and relational databases, managing the dependencies and ensuring they run identically across different environments becomes incredibly difficult. This volume provides the definitive, practical guide to containerizing and orchestrating your full-stack JavaScript and AI applications.

In No More Localhost, you will explore the operational patterns used by DevOps and systems engineers to package, secure, and run applications. By treating infrastructure as code, you will learn to build resilient, portable, and highly optimized environments that eliminate the \"it works on my machine\" problem once and for all.

What you will discover inside:

The Core of Containerization: Learn the low-level systems logic behind Docker, distinguishing containers from virtual machines, and mastering namespaces, control groups (cgroups), and layered filesystems.
Production-Grade Dockerfiles: Build highly optimized images using multi-stage builds. Implement Next.js Standalone Mode, secure your runtime with non-root users, and ensure proper signal handling with processes like tini.
Multi-Container Orchestration: Use Docker Compose to organize your entire stack. Learn to coordinate Node.js, PostgreSQL (with pgvector), and Redis caches, managing startup dependencies with declarative health checks.
Local AI and GPU Passthrough: Configure your local environment to run hardware-accelerated AI models using Ollama and Python/FastAPI, utilizing the NVIDIA Container Toolkit to access physical GPU silicon directly from your containers.
Essential Linux & DevOps Shell Commands: Master the terminal commands needed to manage processes, configure file permissions (chmod), audit logs, and test network pathways.
Security and Vulnerability Scanning: Secure your software supply chain. Learn to scan container layers with Trivy and manage sensitive environment variables and secrets safely at runtime with Zod validation.
High-Performance WebAssembly (WASM): Architect client-side pipelines that execute heavy computation inside headless environments, utilizing Web Workers and SharedArrayBuffer for parallel processing.
Introspective Debugging: Learn how to diagnose running containers without interrupting service, using logs, interactive terminal executions, and remote debugging ports.

Who this book is for:

This book is written for intermediate to advanced JavaScript/TypeScript developers, full-stack engineers, and technical founders who want to build a bridge between application code and robust systems operations. It assumes basic familiarity with Node.js and the command line, building your DevOps foundations step-by-step.

Master the tools of container orchestration and build scalable, secure, and reproducible systems today.

If the book were printed, it would be more than 350 pages long.
