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


Now, we can connect containers in different ways to keep different services separate on different containers. We learned how to do this manually, which can be quite hard when you have lots of dependencies between containers.

We had a brief look at two orchestration tools: Docker Compose and Crane. Crane is an independent and more advanced tool for the administrators who want more control over containers. The ability to group containers in Crane makes it more reliable when there can be timing issues in dependencies.

In the next chapter, we will run two instances of our app using Crane to see what problems and possibilities crop up when we want to make both our blogs publicly accessible on the regular HTTP port (80).
