In the past, I have dealt with Docker before. Now that Docker rootless is no longer experimental, it makes sense for me to look into it again.
The question I have is this:
I want to run Docker rootless and build my images myself.
Most images are still designed so that the process running in the container runs as root.
Since Docker runs rootless, i.e. under a user, I would like to have a user run the process in the image (running container) as well.
Only, does the user have to be the same as the user on the host?
I think (99%) not, but then I am not 100% sure.
