I am using novadocker at centos7, and failed to start an instance with following error:( the openstack stack was setup by latest yum on centos7, and the novadocker was got from https://github.com/openstack/nova-docker in few days) ,
[root@controller ~]# openstack --version
openstack 1.7.2

Hi. I think I had a similar issue .
I have FUEL 7.0 on Virtualbox with 1 compute and 1 controller (ubuntu).
I also had
AttributeError: 'dict' object has no attribute 'container_format'.

In my case
1)I redeployed the compute node
2)did not use the trunk branch! I switched to stable/kilo
3)used requests 2.2.1
4)added json util dumps like this https://ask.openstack.org/en/question/67682/docker-setup-on-kilo/ (see the comments)
5)enabled the tty according to this https://bugs.launchpad.net/nova-docker/+bug/1489985

and it worked
