I have a docker image A built on ubuntu OS.I have a requirement to change the OS to RedHat OS.
Please note I have downloaded the A image from dockerhub and don’t have source code available with me.
Is it possible using multistage docker build option to change the OS of an existing image.
I can try to write my own Dockerfile where I pull A as base image and then try to change the OS. Any idea how it can be done.
