docker updates 12/2014
Just a couple of links with some things that have come out this month.
Docker 1.4.0 and 1.3.3
Looks like this release has an extreme emphasis on bug fixes and platform stability.
Pachyderm File System
Pfs is a distributed file system built specifically for the Docker ecosystem. You deploy it with Docker, just like other applications in your stack. Furthermore, MapReduce jobs are specified as Docker containers, rather than .jars, letting you perform distributed computation using any tools you want.

AWS EC2 Container Service
Mentioned this in an earlier post and I have a few more details now. Integrated with Docker Hub and AWS to use Elastic IP's and other infrastructure. Looks like its going to provide cluster management a built-in scheduler that helps you spread your containers out across your cluster. Great for scaling and looks to be a more complete solution than Google has offered.

To use Amazon ECS, you need to install a custom version of the cli (amazon-ecs-client) for ECS, as this is the only available client.
