Mastering Docker, Fourth Edition - Fourth Edition

Overview of this book

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.

Launching Docker hosts in the cloud using Docker Machine

In this section, we are going to take a look at just one of the public cloud drivers supported by Docker Machine. As already mentioned, there are plenty available, but part of the appeal of Docker Machine is that it offers consistent experiences, so there are not too many differences between the drivers.

We are going to be launching a Docker host in DigitalOcean using Docker Machine. To do this, we need an application programming interface (API) access token with the necessary permissions to access and launch resources within your DigitalOcean account. Rather than explaining how to generate one here, you can follow the instructions at https://www.digitalocean.com/help/api/.

Important note

Launching a Docker host using the API token will incur a cost; ensure you keep track of the Docker hosts you launch. Details on DigitalOcean's pricing can be found at https://www.digitalocean.com/pricing/. Also, keep your API token...
