The stack file is a YAML file, and is basically the same thing as a Docker Compose file. Both are YAML files that define a Docker base application. Technically, a stack file is a compose file that requires a specific version (or above) of the compose specification. Only the version 3.0 specification and above are supported by Docker stacks. If you have an existing project that uses Docker compose YAML files, and those files are using the version 2 or older specification, then you will need to update the YAML files to the version 3 spec to be able to use them with Docker stacks. It is worth noting that the same YAML file can be used with either Docker stacks or Docker compose (provided it is written using the version 3 specification or higher). However, there are some instructions that will be ignored by one or the other tools...

Overview of this book
Docker is an open source software platform that helps you with creating, deploying, and running your applications using containers. This book is your ideal introduction to Docker and containerization.
You will learn how to set up a Docker development environment on a Linux, Mac, or Windows workstation, and learn your way around all the commands to run and manage your Docker images and containers.
You will explore the Dockerfile and learn how to build your own enterprise-grade Docker images. Then you will learn about Docker networks, Docker swarm, and Docker volumes, and how to use these features with Docker stacks in order to define, deploy, and maintain highly-scalable, fault-tolerant multi-container applications.
Finally, you will learn how to leverage Docker with Jenkins to automate the building of Docker images and the deployment of Docker containers. By the end of this book, you will be well prepared when it comes to using Docker for your next project.
