Comment 1 for bug 1602712

Could you attempt the following and report back?

First, make sure that docker permissions aren't the issue. You can fix them later for better security, but start with the following:
$ sudo usermod -aG docker

Then if that doesn't work, you can attempt to modify the following:
$ sudo vi /opt/kolla/ansible/roles/prechecks/vars/main.yml

You'll see max/min settings. Adjust for your Docker version.

Reinstall like the following:
$ sudo pip install ./opt/kolla/ --upgrade

Does that get you past this hurdle?
