I think people are assuming you want to convert people to The Church of Docker, in their minds, if you know what I mean. I do not see it that way, but “what is stopping you from using virtualization” has such a tone as if everyone is supposed to virtualize, but something prevents them and they can’t.

I think a better way to ask it would be “what are your reasons for sticking with bare metal?” or something like that.

sidenote: to me it seems some people here have quite bad experiences with docker. I mean it has parts I don’t like either, but I never had so many problems with it and I’m hosting a dozen of web services locally. maybe their experience was from the early days?
