pip install -e 
git+https://github.com/stackforge/nova-docker#egg=novadocker
cd src/novadocker/ 
git checkout -b pre-i18n 9045ca43b645e72751099491bf5f4f9e4bddbb91
python setup.py installworks fine.
 However, python-oslo-i18n-1.0.0-1.el7.centos.noarch is installed on CentOS 7, I would
expect
 to exist more recent commit in master or another branch suitable for build nova-docker
driver
 on Juno. Attempt to clone all the tree gave me system unable to start containers on
Juno.
 I also had no luck with commit 3fd99f8516f890b45b928b0bce4439bb003c0bb1
 Thanks
 Boris.
