Unlock the full potential of the Docker containerization platform with this practical guide

▶Book Description
Docker has been a game changer when it comes to how modern applications are deployed and created. It has now grown into a key driver of innovation beyond system administration, with a significant impact on the world of web development. Mastering Docker shows you how you can ensure that you're keeping up with the innovations it's driving and be sure you're using it to its full potential. This fourth edition not only demonstrates how to use Docker more effectively but also helps you rethink and reimagine what you can achieve with it.

You'll start by building, managing, and storing images along with exploring best practices for working with Docker confidently. Once you've got to grips with Docker security, the book covers essential concepts for extending and integrating Docker in new and innovative ways. You'll also learn how to take control of your containers efficiently using Docker Compose, Docker Swarm, and Kubernetes.

By the end of this Docker book, you'll have a broad yet detailed sense of what's possible with Docker and how seamlessly it fits in with a range of other platforms and tools.

▶What You Will Learn
-Get to grips with essential Docker components and concepts
-Discover the best ways to build, store, and distribute container images
-Understand how Docker can fit into your development workflow
-Secure your containers and files with Docker's security features
-Explore first-party and third-party cluster tools and plugins
-Launch and manage your Kubernetes clusters in major public clouds

▶Key Features
-Explore tools such as Docker Engine, Machine, Compose, and Swarm
-Discover how you can integrate Docker into your everyday workflows
-Get well-versed with Kubernetes options such as Minikube, Kind, and MicroK8s

▶Who This Book Is For
If you are a software architect, DevOps engineer, sysadmin, or IT professional looking to leverage Docker's extensive features for innovating any process from system administration to web development, Mastering Docker will show you how you can use it to its full potential. A basic understanding of containerization and prior Docker experience is necessary.

▶What this book covers
- Chapter 1, Docker Overview, discusses where Docker came from and what it means to developers, operators, and enterprises.

- Chapter 2, Building Container Images, looks at the various ways in which you can build your own container images.

- Chapter 3, Storing and Distributing Images, looks at how we can share and distribute images, now that we know how to build them.

- Chapter 4, Managing Containers, takes a deep dive into learning how to manage containers.

- Chapter 5, Docker Compose, looks at Docker Compose―a tool that allows us to share applications comprising multiple containers.

- Chapter 6, Docker Machine, Vagrant, and Multipass, looks at Docker Machine and other tools that enable you to launch and manage Docker hosts on various platforms.

- Chapter 7, Moving from Linux to Windows Containers, explains that, traditionally, containers have been a Linux-based tool. Working with Docker, Microsoft has now introduced Windows containers. In this chapter, we will look at the differences between the two types of containers.

- Chapter 8, Clustering with Docker Swarm, discusses how we have been targeting single Docker hosts until this point. Docker Swarm is a clustering technology provided by Docker that allows you to run your containers across multiple hosts.

- Chapter 9, Portainer ？ a GUI for Docker, explains that most of our interaction with Docker has been on the command line. Here, we will take a look at Portainer, a tool that allows you to manage Docker resources from a web interface.

- Chapter 10, Running Docker in Public Clouds, is where we look at the various ways in which you can run your containers in public cloud services.

- Chapter 11, Docker and Kubernetes, takes a look at Kubernetes. Like with Docker Swarm, you can use Kubernetes to create and manage clusters that run your container-based applications.

- Chapter 12, Discovering other Kubernetes options, is where, having used Docker to run Kubernetes locally, we take a look at other options for getting up and running with Kubernetes on your local machine.

- Chapter 13, Running Kubernetes in Public Clouds, takes a look at various Kubernetes offerings from the 'big four' cloud providers: Azure, Google Cloud, Amazon Web Services, and DigitalOcean

- Chapter 14, Docker Security, takes a look at Docker security. We will cover everything from the Docker host to how you launch your images, where you get them from, and the content of your images.

- Chapter 15, Docker Workflows, starts to put all the pieces together so that you can start using Docker in your production environments and feel comfortable doing so.

- Chapter 16, Next Steps with Docker, looks not only at how you can contribute to Docker but also at the larger ecosystem that has sprung up to support container-based applications and deployments.

출판사 서평

▶ Preface
Docker is a game-changer when it comes to modern applications' architecture and how they are deployed. It has now grown into a key driver of innovation beyond system administration, and it has had a significant impact on the world of web development and beyond. But how can you make sure you're keeping up with the innovations it's driving? How can you be sure you're using it to its full potential?

This book shows you how; it not only demonstrates how to use Docker more effectively, it also helps you rethink and re-imagine what's possible with Docker.

You will cover basic topics, such as building, managing, and storing images, along with best practices, before delving into Docker security. You'll find everything related to extending and integrating Docker in new and innovative ways. Docker Compose, Docker Swarm, and Kubernetes will help you take control of your containers in an efficient way.

By the end of the book, you will have a broad and detailed understanding of exactly what's possible with Docker and how seamlessly it fits into your local workflow, highly available public cloud platforms, and other tools.
