Before shipping your application, there are a few terms to learn, as they are used throughout this guide.
An application (or app) is the software package you are installing onto your customer’s servers. It isn’t a single binary, rather it’s all of the individual components which make your product.
Channels are used to stage out releases for customers or customer segments. By default there are Stable, Beta and Unstable channels.
A release is a shipped version of the application, complete with release notes & version number.
An image is a Docker image that will be used to create a container at runtime.
A container is a running instance of an image.
