What's the point of using Docker within a VM...?

  "Providing machines for Kubernetes in not only necessary as a pool of raw cycles and bytes but also can provide a critical extra layer of security". [0] Maybe it's true for now, but containers may be enough security in the future.

  It's vital if you use a Mac/Win as a dev machine.

  @daveoflynn is correct the LXC founding that docker is built on only currently works in Linux.

    BTW, they are still Linux only, but do not use LXC anymore. LXC was replaced with libcontainer. http://www.infoq.com/news/2014/03/docker_0_9 http://www.infoq.com/news/2014/03/docker_0_9

  The reasons are actually not any different than when running on a dedicated machine; running containers is a good idea, regardless of whether it's a VM. Containerization is a smaller, granular unit of isolation than a VM, and it's complementary to virtualization, not a replacement/competitor.
