OVERVIEW
The Docker project provides the means of packaging applications in
lightweight containers. Running applications within Docker containers
offers the following advantages:
- *Smaller than VMs*: Because Docker images contain only the content
needed to run an application, saving and sharing is much more efficient
with Docker containers than it is with virtual machines (which include
entire operating systems)
- *Improved performance*: Likewise, since you are not running an
entirely separate operating system, a container will typically run faster
than an application that carries with it the overhead of a whole new
virtual machine.
- *Secure*: Because a Docker container typically has its own network
interfaces, file system, and memory, the application running in that
container can be isolated and secured from other activities on a host
computer.
- *Flexible*: With an application's run time requirements included with
the application in the container, a Docker container is capable of being
run in multiple environments.
I honestly thought Docker *was* a container VM. Maybe I have a
misconception?
So just like a VM conatiner like VMWare running on the host pc, but
instead of running Operating Systems inside you run APPs that have been
"APP-ified."

Post by Adam MoffettNo....a container has to run on a host. The host and the container
have to run the same OS.
The benefits come from the container being able to share the resources of
the host instead of virtualizing the hardware in it's entirety.
I'm not actually sure how big the benefits are.
I'm dumb I suppose. I'm not following. What Bill said makes the most
sense. Like Wine for Windows apps on Linux, this thing bundles up the app
and all of it's dependancies and resources into a portable container. You
can then run that on any compatible OS? Is there a server that has to
"serve" them?

Post by Josh BairdNo, it's a container that can be ran within existing operating systems.
Post by Ty FeatherlingWhut?? Is this a universal app server?

Post by Bill PrinceJust had breakfast with a couple of old work buddies. This is the new
thing. You don't need VMs anymore....
