{ "item_title" : "Getting Started with Docker", "item_author" : [" Rakesh Kumar "], "item_description" : "Software development has evolved dramatically over the past few decades. Applications that once ran on a single computer are now distributed across cloud platforms, mobile devices, data centers, and edge computing environments. As businesses strive to deliver software faster and more reliably, ensuring that applications run consistently across different environments has become one of the greatest challenges for developers and IT teams.A common problem in software development has always been the phrase, It works on my machine. An application may function perfectly on a developer's laptop but fail when deployed to a testing server or production environment due to differences in operating systems, libraries, dependencies, or configuration settings. These inconsistencies often lead to deployment delays, increased costs, and frustrated development teams.Docker revolutionized software deployment by introducing a lightweight and portable approach through containerization. Instead of packaging only application code, Docker packages the application together with its runtime, libraries, dependencies, and configuration into a standardized container. This container can run consistently on a developer's computer, a testing server, a private data center, or any major cloud platform. Docker has transformed the way organizations build, test, deploy, and maintain modern applications.Today, Docker has become a foundational technology in cloud computing, DevOps, microservices, continuous integration and continuous deployment (CI/CD), edge computing, and cloud-native application development. Organizations of all sizes-from startups to global enterprises-use Docker to accelerate software delivery, improve scalability, simplify infrastructure management, and increase operational reliability.This book, Getting Started with Docker: Build, Ship, and Run Anywhere, has been written to provide a practical, beginner-friendly, and comprehensive introduction to Docker. Whether you are a student, software developer, DevOps engineer, system administrator, cloud architect, or technology enthusiast, this book will guide you from the fundamentals of containerization to building and deploying real-world Docker applications.The journey begins by explaining the evolution of software deployment and the need for containerization. You will then learn the core concepts of Docker, including Docker Engine, images, containers, Dockerfiles, volumes, networking, and Docker Compose. As your knowledge grows, you will explore best practices for creating optimized and secure Docker images, managing persistent storage, connecting multiple containers, and debugging containerized application.To reinforce learning, the book includes numerous hands-on examples, architectural diagrams, command-line demonstrations, and real-world case studies. These practical exercises are designed to help you develop confidence in building, running, troubleshooting, and deploying Docker-based applications. By working through an end-to-end full-stack project, you will experience how Docker is used in professional software development environments. By the time you complete this book, you will be able to confidently create Docker images, manage containers, design multi-container applications, secure Docker environments, optimize deployments, and prepare production-ready applications for deployment in the cloud. More importantly, you will understand how Docker fits into the broader software development ecosystem and how it empowers teams to build, ship, and run applications anywhere with consistency and confidence.Whether you are taking your first steps into containerization or strengthening your existing software development skills, this book aims to be your trusted companion on the journey toward mastering Docker. Welcome to the exciting world of containerization, and let us begin building, shipping, and running applications anywhere with Docker.", "item_img_path" : "https://covers2.booksamillion.com/covers/bam/9/79/818/548/9798185481585_b.jpg", "price_data" : { "retail_price" : "35.00", "online_price" : "35.00", "our_price" : "35.00", "club_price" : "35.00", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
