Overview of this book

<p>Docker is a great tool in many ways for developers and people in DevOps.</p> <p>We begin by learning how easy it is to create and publish your own customized Docker images and making them available to everyone. We also see how practical it is to separate every service to its own container. When you have published separated service containers, the process of running all kinds of platforms in the same server for easier cloud computing is a walk in the park.</p> <p>This book walks you through a use case project that will teach you how to customize and create your own Docker image, allowing you to run any platform you want. The project evolves throughout the book and emerges as a complete three containers Wordpress/MySQL platform when finished.</p> <p>By the end of the book, you will know how to create such a container on a Wordpress/MySQL platform, among others.</p>

Summary


In this chapter, you learned that you can keep your data out of your service containers using data volumes. Data volumes can be any one of directories, files from the host's filesystem, or data volume containers.

We explored how we can pass parameters to containers and how to read them from inside ENTRYPOINT. Parameters are a great way to configure containers, making it easier to create more generalized Docker images.

We created a data volume container and published it to the Docker Registry Hub, preparing us for the next chapter, where we will connect our three containers to create one loosely coupled unit.
