Overview of this book

Making sure that your application runs across different systems as intended is quickly becoming a standard development requirement. With Docker, you can ensure that what you build will behave the way you expect it to, regardless of where it's deployed. By guiding you through Docker from start to finish (from installation, to the Docker Registry, all the way through to working with Docker Swarms), we’ll equip you with the skills you need to migrate your workflow to Docker with complete confidence.

Chapter 2. Application Container Management

In this lesson, we will scale one of the containers we built into a multi-tier setup. This will involve splitting the application into different logical sections. For example, we could have an application running on a Docker container and the application's data in a separate database container; however, both should work as a single entity. For this, we will use Docker's tool for running multi-container applications. The tool goes by the name docker-compose. In summary, docker-compose is the tool used for defining and running multi-container Docker applications.
