Docker (http://docker.io) is an open-source project which allows server administrators and developers to easily package and manage services (e.g. a webserver, a database, a webcrawler) into (linux) /containers/. These (LXC) Containers are somewhat similar to Virtual Machines. They can be easily created on one machine and moved (and copied) to others.
About the name: A Docker is a person whom loads and offloads ships. Nowadays these are the container crane operators. But they used to be strong guys carrying bags and crates. This resembles the product.

Diseño de inspiración
The whole point of Docker is that software code can now be easily packaged, moved, stacked and so forth. it could be nice to express some of this in the logo.
I think a 'mascotte' illustration would work well, but the logo will also need to be used on a github like site, and there might not be a lot of space for it; it has to work while the image is no more than, say 40px high. It could be cool if there was a larger illustration and a simplified icon profile. But this is definitely not a requirement.
