No. Docker just supports provisioning containers. Take a high level view of a data centre with 10,000 machines, you need orchestration software that knows about and automates these 10k machines, which ones are online/offline, utilization, storage, networking, current state, power distribution (what happens if a racks power drops out?), etc and then provisions these containers onto that hardware. Think of this orchestration software like a brain, and it knows about the current state of things, keeps a watch on what is happening in the data centre, fixes things when they go bad, and knows where to put things when you want to do something.

  Docker --> hardware
  Orchestration software --> Docker/LXC/VM/etc --> hardware

An additional example would be dotCloud (makers of Docker), they have orchestration software sitting atop Docker, which knows about users, machines, etc and then provision these docker instances on AWS hardware.

   dotCloud (orchestration software) --> Docker --> AWS EC2 (hardware)

There is a great wired article (linked to below [1] and in the OPs story), which outline how Google uses this orchestration software in its day-to-day operations. There is this great diagram [2], which shows Omega (Google's orchestration software), and how it deploys containers for images, search, gmail, etc onto the same physical hardware. There is an amazing talk by John Wilkes (Google Cluster Management, Mountain View) about Omega at Google Faculty Summit 2011 [3], I would highly recommend watching it!

ps. Orchestration software has a global view of resources across all machines, so it knows how to get the best utilization out of all these machine (think jigsaw puzzle). You submit a container profile to the orchestration software, things like instance lifetime, cpu, storage, memory, redudance, and the software will figure out where to place your instances.
