9. High level approach:
   lightweight VM
   •  own process space
   •  own network interface
   •  can run stuff as root
   •  can have it’s own /sbin/init
   (different from the host)
   “Machine Container”

10. Low level approach:
    chroot on steroids
    •  can also not have it’s own /sbin/init
    •  container = isolated process(es)
    •  share kernel with the host
    “Application Container”

13. Standard format for containers and a
    place to share them
    •  Fetch an image from the public registry with
    “docker pull”
    •  Enter an image with “docker run“ and do some
    changes
    •  Record those changes with “docker commit”,
    repeat as many times as needed
    •  And then share the result with “docker push” on
    the public registry, or a private one
