Recently Filip Krikava made a fork on github and created a Juno branch using
the latest commit + Fix the problem when an image is not located in the local docker image registry
Master https://github.com/stackforge/nova-docker.git is targeting latest Nova ( Kilo release ), forked branch is supposed to work for Juno , reasonably including commits after "Merge oslo.i18n". Posting bellow is supposed to test Juno Branch https://github.com/fikovnik/nova-docker.git
Quote ([2]) :-
The Docker driver is a hypervisor driver for Openstack Nova Compute. It was introduced with the Havana release, but lives out-of-tree for Icehouse and Juno. Being out-of-tree has allowed the driver to reach maturity and feature-parity faster than would be possible should it have remained in-tree. It is expected the driver will return to mainline Nova in the Kilo release.
Install required packages to install nova-dockker driver per https://wiki.openstack.org/wiki/Docker
