build.sbt imports for docker commands

Question

I have a build.sbt file but I am not able to figure out the role of this import import docker.{addDockerPackage}

Is this an open source import? I am not able to find info about it. Further down in the script it calls a method addDockerPackage()

I wonder if the method is in that package? Or all this is some proprietary stuff? If it is a standard import, where do I read about it?

You can use sbt-native it has a Docker plugin:

Here are 4 different good example that you can run to see how it works:

As far as:

import docker.{addDockerPackage}    

I don't think that is a package. It looks more like a helper to define something like this:

packageName in Docker := packageName.value
