Open Stack

Yes for now. Simply install the docker and configure it to allow non-root
user to use it. However, it would be nice if installing/configuring docker
is done by devstack. I created a ticket for that:
https://bugs.launchpad.net/zun/+bug/1614122 .

BTW, you need to specify the command of the container. Otherwise, it will
exit right after start.

$ zun container-create --image ubuntu --name test1 --command "bash -c
'while true; do echo hello; sleep 1; done'"

Best regards,
Hongbin
