The official Odoo docker images have been published on docker.com

https://registry.hub.docker.com/_/odoo/

The docker file is maintained in this repository

https://github.com/odoo/docker

They depends on postgresql images, usage is pretty simple:

$ docker run -d -e POSTGRES_USER=odoo -e POSTGRES_PASSWORD=odoo --name db postgres
$ docker run -p 127.0.0.1:8069:8069 --name odoo --link db:db -t odoo

We will update the install/deploy documentation to mention them.
