Comparing containers (a concept) with VM/jails/zones is a non-sequitur. To quote: A “container” is just a term people use to describe a combination of Linux namespaces and cgroups. Linux namespaces and cgroups ARE first class objects. NOT containers. [...] VMs, Jails, and Zones are if you bought the legos already put together AND glued. So it’s basically the Death Star and you don’t have to do any work you get it pre-assembled out of the box. You can’t even take it apart. Containers come with just the pieces so while the box says to build the Death Star, you are not tied to that. You can build two boats connected by a flipping ocean and no one is going to stop you. Docker is a bunch of boxes floating on a flipping ocean[1]. They could have made a deathstar, but they chose not to.
