I've started using quay.io to store my docker images. I have not used the service heavily (because I'm still building out my Dockerfiles), but what I have used has been great.

Docker.io is great to use to store images, unless you don't want them public. I have proprietary apps loaded on my images so making them public is not an option.

So far Docker is set to solve my scalability problem that i've been seeking for the past year. Since VMs are not ideal, I start with a farm of bare ubuntu servers and scale out to VM's in the cloud if needed. With Docker I can configure once and deploy to all of these nodes no matter how they were built. I stopped using Chef when I realized I could accomplish my goals with a fraction of the complexity and effort.
