Docker image hierarchy

Question

I would like to check which image is the parent of my given Docker image (FROM with the image layer they created). How can I get this information?

I tried to do it through

docker images -t

but this flag is deprecated in new versions of Docker. Is there a reliable source of such information?

The docker tree is out of date before a good replacement has been proposed (see discussion in PR 5001 )

This is currently an outward expression justone/dockviz.

 alias dockviz="docker run --rm -v /var/run/docker.sock:/var/run/docker.sock nate/dockviz"

Information about the image is rendered by lines indicating the parent image:

dockviz images -d | dot -Tpng -o images.png

like a tree in the terminal:

$ dockviz images -t
