Docker driver for Openstack

I am working on a OpenStack installation but I cant get it to work with Docker. Without Docker it seems to work, but when I try to start an instance, I get an exception that no host is available. I found out that at my computing nodes the Docker driver cannot be found:

2014-04-21 10:51:26.114 1629 ERROR nova.virt.driver [-] Unable to load the virtualization driver

2014-04-21 10:51:26.114 1629 TRACE nova.virt.driver

This is very strange to me because the Docker driver has been suggested in the manual: http://docs.openstack.org/trunk/config-reference/content/docker.html Although I cannot find it in the GIT: https://github.com/openstack/nova/tree/master/nova/virt

Also a variety of sites suggest this driver in their tutorial. I am running the new Icehouse and I've got Docker installed on the local machines. Do you guys have any thoughts? Please let me know!

The Docker Driver for Openstack Nova has been removed.

"The docker compute driver does not currently have CI running against it. In accordance with our plan to require this for all drivers, we are now removing the driver from nova." :

https://review.openstack.org/#/c/79740/

The docker driver is now located in Stackforge :

Please check you have installed docker-py by using below command:

pip install docker-py

Since you are installing for Icehouse, actually current nova-docker-driver can only support for Kilo release. Below is my experience installing in Juno for your reference. Please download the version of nova-docker-driver in below(Sep. 17 released)

git clone https://github.com/stackforge/nova-docker.git

cd nova-docker/

git checkout -b pre-i18n 9045ca43b645e72751099491bf5f4f9e4bddbb91

This way can help you to use a previous release to support an older OpenStack.
