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.
