Description
How Containers Work (Wizard Zines) takes a look at one of the hottest technologies of the day, containers and Docker, and emphasizes the principle that “containers are not magic.” By dissecting the Linux operating system, the author shows that containers are actually a combination of several internal features of the Linux kernel that work together to create an isolated environment.
Throughout this guide, the reader will be introduced to the basic concepts that containers are built on. The author even goes further and explains how to build a small container engine (Mocker) to prove that by understanding a few simple concepts in Linux, it is possible to easily understand the complexities of tools like Docker and use them at scale.
