Book synopsis

Build, run, test, secure, and deploy modern applications with Docker without treating containers as a collection of disconnected commands.

Docker for Developers is a practical guide for developers who want to understand how Docker fits into a complete software development workflow. Rather than focusing only on individual commands, this book shows how images, containers, Dockerfiles, volumes, networks, Docker Compose, testing, security, registries, CI/CD, and deployment work together.

Throughout the book, you will build and evolve TaskFlow, a practical containerized application using Python, Flask, PostgreSQL, and Docker Compose. You will learn how to create efficient Docker images, manage persistent data, connect multiple services, separate development and production environments, handle secrets, troubleshoot container problems, automate testing, publish versioned images, and prepare applications for production deployment.

Inside this book, you will learn how to:

• Build and manage Docker images and containers confidently

• Write clean, maintainable Dockerfiles

• Work with volumes, bind mounts, ports, and Docker networks

• Build multi-container applications with Docker Compose

• Create practical development and testing environments

• Manage environment variables and secrets securely

• Optimize images and run containers with reduced privileges

• Debug container, network, storage, and configuration problems

• Publish versioned images to container registries

• Integrate Docker with CI/CD workflows

• Deploy containerized applications with production-oriented practices

Whether you are new to Docker or already using containers without fully understanding how the pieces fit together, this book will help you move from basic container commands to a complete, professional Docker workflow.

Start building more consistent, portable, and production-ready applications with Docker today.
