Docker Deep Dive

By: Nigel Poulton

Overview of this book

Most applications, even the funky cloud-native microservices ones, need high-performance, production-grade infrastructure to run on. Having impeccable knowledge of Docker will help you to thrive in the modern cloud-first world. With this book, you’ll gain the skills you need to work with Docker and its containers. The book begins with an introduction to containers and explains its functionality and application in the real world. You’ll then get an overview of VMware, Kubernetes, and Docker and learn to install Docker on Windows, Mac, and Linux. Once you’ve understood the Ops and Dev perspective of Docker, you’ll be able to see the big picture and understand what Docker exactly does. The book then turns its attention to the more technical aspects, guiding your through practical exercises covering Docker engine, Docker images, and Docker containers. You’ll learn techniques for containerizing an app, deploying apps with Docker Compose, and managing cloud-native applications with Swarm. You’ll also build Docker networks and Docker overlay networks and handle applications that write persistent data. Finally, you’ll deploy apps with Docker stacks and secure your Docker environment. By the end of this book, you’ll be well-versed in Docker and containers and have developed the skills to create, deploy, and run applications on the cloud.

16: What next

Hopefully you’re feeling confident with Docker and ready to take your next steps. Fortunately, taking those next steps has never been easier.

Practice makes perfect

There’s no substitute for hands-on practice. Fortunately, as we showed in Chapter 3, it’s easier than ever to get Docker and start developing your hands-on skills. I personally use Docker Desktop every day and regularly use Play with Docker when I need to test something quickly with multiple nodes.

Video training

Video training is another way to learn things and see stuff in action.

I’ve created a lot of high-quality Docker video training courses at Pluralsight. If you’re not a member of Pluralsight then become one! It costs money, but it could be one of the most important career investments you ever make. And if you’re unsure about parting with your hard-earned money… they always have a free trial where you can get free access to my courses for a limited...
