I love this idea, and want to try it but I have no experience with Docker (on the todo list).

I wanted to spin up an instance of Sphinx Search but no idea how to go about doing it.

Maybe creating a set of tutorials will help with this. I can think of two advantages. The first being customers like myself will love it. Second, similar to Linode and their tutorials it will drives a lot of traffic and establishes your reputation as docker experts. Will probably build a lot of back-links too as people link to your tutorials.

This is truly awesome, nice work! I configured and launched a machine with redis and node in less than 5 minutes. Very cool. How will you isolate instances from each other? My instance appears to have 24 GB of RAM and 12 cores, and it looks like I can use all of it in my instance.

You can limit Docker to have CPU weight shares, and also a memory limit. The file storage limits are due to Docker 0.7, and for now you can ulimit them.

Docker uses LXC which supports memory and CPU limits

Perhaps http://aws.amazon.com/dedicated-instances/

building a virtualization infrastructure on top of another, black box virtualization infrastructure…

What could possibly go wrong?

A traceroute of their blog, or a server you just spun up? They don't necessarily have to eat their own dogfood.

If you offer infrastructure services and don't eat your own dogfood you can't be serious.

If you offer infrastructure services and don't tell people where and how you provide it, you can't be serious, too.

Looks cool. Here's what I'd love to see: built-in git deployment (ie. take a Dockerfile, build an image from it, and then after a push add the latest source code to /app and start new instances), and some kind of orchestration so you could run a number of app containers behind a load balancer container.
