What is Undock?

Undock is a CLI tool for unpacking files from container images into a local directory, without having to run the image as a container.

It is useful when an image is being used as a transport format rather than something you want to launch, for example release artifacts, generated assets, root filesystems, or any other files published in an image. Undock reads the image from supported sources, lets you extract exactly what you need, and writes it to disk with a single command.

See the usage examples for more info.
