Docker is a powerful tool, but learning how to use it effectively can be time-consuming. If you are used to the old paradigms of development and deployment, this paradigm shift to Docker's containerization can be challenging, as it introduces completely new concepts and workflows.

Docker's approach to isolated environments, image management, and microservice architecture requires a significant shift in understanding from traditional methods.

Many engineers and developers feel overwhelmed by the rapidly growing cloud and containerization ecosystem, making it challenging for them to enter the world of containers.

The rapidly changing ecosystem of containers can present challenges and confusion for operations engineers and developers. As containerization technology continues to evolve, it is important to stay up-to-date and adapt to these changes. This technology is transforming the way system engineering, development, and release management have traditionally worked, making it a crucial aspect of modern IT.

"Painless Docker" aims to bridge this gap, providing a comprehensive guide to help you smoothly transition to Docker's innovative ecosystem, enhancing your development and deployment processes efficiently.

"Painless Docker" serves as a gateway to Docker's world, helping you become proficient in its usage. You'll discover that using Docker is easy and efficient for your development and operations environments.

"Painless Docker" is a comprehensive and detailed guide that covers Docker and a significant portion of its ecosystem. This guide is designed for beginners and intermediate levels, providing step-by-step guidance. It starts with basic concepts and progresses to advanced features. By the end, readers will have mastered Docker and microservices, including their development and production usage. The guide also covers Docker Compose, Docker Swarm, and important tools from the ecosystem.

These are the 10 most important things you will learn:

Basics and advanced concepts of Docker: An in-depth exploration of Docker beyond just an introduction.
Building and deploying your own images in production: From the build process to running containers.
Docker volumes, storage management, filesystems, and storage drivers.
Networking and advanced concepts such as SDN, cloud drivers, and more.
Optimizing Docker: Techniques for creating efficient images and running containers.
Building tools that integrate with Docker using the Docker API.
Docker logging and debugging: Monitoring Docker health and troubleshooting issues.
Docker orchestration using Swarm: Overlay networks, ingress, and tools for setting up a production cluster.
Understanding how Docker works and how to build your own Docker (containerd, runC, shim, namespaces, seccomp, cgroups..etc)
Docker security and best practices: Essential knowledge for maintaining a stable and secure production system.

For developers, system administrators, QA engineers, operation engineers, architects, and anyone faced to work in one of these environments in collaboration with the other or simply in an environment that requires knowledge in development, integration, and system administration. Historically, the worlds of developers and sysadmins operated in parallel silos, each with its own distinct mindset and set of challenges. Developers were often driven by the mandate to innovate and deliver new features. They perceived their role as one of creating code and applications tailored for optimal functionality. On the other hand, system administrators were the gatekeepers of stability and security. Their primary objective was to ensure that machines functioned efficiently and securely, a task that often required meticulous maintenance and optimization.
