Docker technology is fast becoming popular compared to Virtual Machines (VMs) and keeping up with that means finding information about how it works, to build knowledge and skills to use it.
In this book review, we uncover the contents of a Free Packet Publishing Guide, Understanding Docker, an ebook that you can use to start your journey with Docker technology.
This book covers the basics about Docker, and it is divided into three major sections that each talk about important things you should know about Docker.
- Docker versus typical VMs
- The Dockerfile and its function
- Docker networking/linking
- Types of installers and how they operate
- Controlling your Docker daemon
- The Kitematic GUI
- Useful commands for Docker, Docker images, and Docker containers
The first section talks about a general understanding of the structure of Docker and the flow of events in the Docker world in comparison to Virtual Machines (VMs).
