Discover the possibilities of Docker

This book about Docker introduces you to a tool used for developing, distributing, and running applications in containers. If you are looking for a clear introduction to container management and related principles, this publication can help you better understand the basics and common practices.

Docker enables the creation and management of isolated containers that typically include everything needed to run an application - such as libraries, configuration files, and code. This often makes it easier to move applications between different environments because it reduces issues caused by differing dependencies. In practice, this can simplify testing and deployment, especially when the environment is configured correctly.

Whether you are working on personal projects or larger applications, Docker is among the commonly used tools in modern software development and operations. The publication focuses on how to leverage its capabilities for developing and deploying applications.

Benefits of Docker

• Simplicity and flexibility - containers can be created and managed in a standardized way.
• Portability - applications can often be run more consistently across environments if the same conditions and configurations are maintained.
• Environment isolation - can limit conflicts between applications and dependencies.
• Time savings - can speed up deployment and testing, especially in repeatable build and deploy processes.
• Broad support - there is an extensive community and a range of related tools.

General characteristics of Docker

• A containerization platform used for developing, packaging, and managing applications.
• Multi-platform support - in practice, Docker is used on Linux, Windows, and macOS (depending on the specific edition and configuration).
• Ability to integrate with CI/CD tools and cloud services.
• Work with images and their versioning; the ability to create custom Docker images.
• Efficient use of resources compared to full virtual machines in many common scenarios.
