Who This Book Is For

This book is intended for those who want to take full advantage of separating services into module containers and connect them to form a complete platform. It will give you all the insights and knowledge needed to run your own PaaS.

In Detail

Docker is a great tool in many ways for developers and people in DevOps.

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 is a walk in the park.

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.

By the end of the book, you will know how to create such a container on a WordPress/MySQL platform, among others.

It can be used to mount volumes, link containers, and so on: dokku docker-options:add myapp "-v /host/path:/container/path" dokku docker-options:add myapp "-link container_name:alias" URL:
