Note that devstack is going to break for docker and Nova master right
now. We're in the middle of moving the docker driver. In the meantime,
use a rev of Nova before this merge:
https://review.openstack.org/#/c/79740/
Once the following change for the new repo merges, we can update
devstack to reflect the new location:
https://review.openstack.org/#/c/79900/
If you really want to use HEAD of Nova master in the meantime, you can
install the docker driver from here:
https://github.com/russellb/nova-docker
Then configure nova.conf with:
compute_driver=novadocker.virt.docker.driver.DockerDriver
