When you start a docker instance in openstack it creates a hostname like : instance-000000xy Is it possible to create the docker instance with the same hostname as the instance name in horizon?

We use Openstack Juno on Ubuntu 12.04 with latest docker (1.4.1)

Not without changing the driver source code, no. The driver explicitly sets the container hostname to this generated instance name. You could patch the code to use the instance hostname instead; the actual changes to the code should be minimal.

I did that, but when you change it to use the hostname in the driver the network is not working.

You would of course need to update the other sections of code that rely on the hostname to locate the container (e.g., in _find_container_by_name, and anything that calls it). So, maybe not minimal after all.
