Overview of this book

No doubt Docker Containers are the future of highly-scalable software systems and have cost and runtime efficient supporting infrastructure. But learning it might look complex as it comes with many technicalities. This is where The Docker Workshop will help you. Through this workshop, you’ll quickly learn how to work with containers and Docker with the help of practical activities.? The workshop starts with Docker containers, enabling you to understand how it works. You’ll run third party Docker images and also create your own images using Dockerfiles and multi-stage Dockerfiles. Next, you’ll create environments for Docker images, and expedite your deployment and testing process with Continuous Integration. Moving ahead, you’ll tap into interesting topics and learn how to implement production-ready environments using Docker Swarm. You’ll also apply best practices to secure Docker images and to ensure that production environments are running at maximum capacity. Towards the end, you’ll gather skills to successfully move Docker from development to testing, and then into production. While doing so, you’ll learn how to troubleshoot issues, clear up resource bottlenecks and optimize the performance of services. By the end of this workshop, you’ll be able to utilize Docker containers in real-world use cases.

Preface

Docker Engine

Docker Engine is the interface that provides access to the process isolation features of the Linux kernel. Since only Linux exposes the features that allow containers to run, Windows and macOS hosts leverage a Linux VM in the background to make container execution possible. For Windows and macOS users, Docker provides the "Docker Desktop" suite of packages that deploy and run this VM in the background for you. This allows Docker commands to be executed natively from the terminal or PowerShell console of the macOS or Windows host. Linux hosts have the privilege of directly executing the Docker Engine natively because modern versions of the Linux kernel support cgroups and namespace isolation.

Note

Since Windows, macOS, and Linux have fundamentally different operating system architectures in terms of networking and process management, a few of the examples in this book (specifically in regard to networking) are sometimes called out as having different behaviors...
