You're being a bit obtuse or maybe you just wanted to show off your knowledge a bit. I said basically the same, "it's a process... with namespaces and cgroups."

You're being a bit obtuse or maybe you just wanted to show off your knowledge a bit. I said basically the same, "it's a process... with namespaces and cgroups." If they can answer that and know what that means, I'm good and I go to my other interview questions. I'm not hiring a Docker developer or someone who needs to know the internals of Linux. I'm hiring SREs who manage and oversee Docker and Kubernetes production environments.

Technically you don’t need to know what a container “is” to oversee Docker and Kubernetes production environments (knowing that it’s not a VM is a plus, but then you already knew that by calling it a container rather than a VM). A container can just be a container, and you can leave it at that. If a zookeeper starts talking about jackdaws and crows in an interview, who’s the one being obtuse and trying to show off their knowledge? The important thing is that the animals are taken care of and the zoo visitors are happy.

  I have apps running in docker and I also deployed apps to VMs. I would get this answer wrong according to OP. Honestly I don't see how this knowledge is necessary.

    Your username is apt. Want to be better than average? Buck up and learn the technology.

      Kinda harsh coming from an IBM employee to be honest.

        This tired trope? Average dev makes average insult, par for the course I guess.

  An SRE responsible for Kubernetes and Docker production environments who doesn't understand the fundamentals of how they work wouldn't be of much use to me. Sure they can probably follow scripted runbooks but I want people who can deep dive into advanced trouble-shooting. TBF, there are uses for those that don't get it, but they're usually the lesser paid folks who work night and weekend on-call rotations.

    > I want people who can deep dive into advanced trouble-shooting In my experience, people who need to know every little thing rarely end up knowing every little thing, and are actually the absolute worst at fixing issues of high urgency - due to needing to know every little thing. I'd much rather have people who are able to learn fast on the fly. Those are the people who actually end up knowing the little things that are actually useful, as opposed to useless trivia.
