I asked a similar question a few minutes ago, and I found the
docker diff command that shows the differences in the file system between a container and its base image. But I realized afterward my need is more complex than that.
I have a Docker image, and I know that Docker image was build from a given base image. Is there a way to list the filesystem changes between those two images?
Here is an example:
sh$ sudo docker image ls
REPOSITORY TAG IMAGE ID
rogueimage latest 77a21f689dcd
ubuntu 18.04 47b19964fb50
rogueimage:latest is based on
ubuntu:18.04 but I would like to know the filesystem difference between the two images. How to do that?
