@stefano wauw.

@stefano Maybe he meant the base image used in the container? But even there, I would prefer Alpine over Ubuntu, unless there is a good reason not to.

@stefano docker can run under vm?

@stefano Honestly - I can understand. I've seen production environments where every admin just fired up servers with distro he likes best. They had like 10 different (or more) Linux and BSDs, including different major versions, and so on.
And every time they had staff changes, some boxes were left orphaned with no maintainer. So it might be a reason behind the wish to use a certain distro, beside that argument they tried to give you.

@stefano Some people seem to not understand how #docker works...

• It is literlly designed to not depend on the specifics of the underlying #Linux distro.

At that point I'd just lie and tell them: "Try it, it'll work or your Ubuntu is fucked up!"

@stefano because Linux is Ubuntu and Ubuntu is Linux
