It's a newbie question.
Given a sample .NET Core application. Using tutorials, I've built a docker image and I can run it via docker run at my local machine (Win10). Docker uses Linux containers.
Now I want to obtain this image somehow at my testing machine (Ubuntu-18.04, docker is installed).
How to do this?
Can docker image be redistributed as a file, using simple copying?
Unfortunately, all reading I've found ends up with running image locally.
