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.

"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.
