I just tested the top one :-

 yum install docker-io -y
 yum install -y python-pip git
 git clone https://github.com/stackforge/nova-docker.git
 cd nova-docker/
 git checkout 07a57f78aa4b01c2acfb84b0e9e723dabfd650cb
 python setup.py install
 systemctl start docker
 systemctl enable docker
 chmod 660  /var/run/docker.sock
 mkdir /etc/nova/rootwrap.d

Afterwards I was able reproduce http://cloudssky.com/en/blog/Nova-Doc...
until the point 

nova boot --image busybox --flavor m1.tiny --key-name osxkey busybox

Instance spawning for a while and gets ERROR status.

git checkout -b pre-i18n 9045ca43b645e72751099491bf5f4f9e4bddbb91

works fine.
Following https://ask.openstack.org/en/question... fresh Juno branch tested on CentOS 7 Juno VM ( just installed ) 

# git clone https://github.com/fikovnik/nova-docker.git
# cd nova-docker
# $ git branch -v -a
* master                1ed1820 A note no firewall drivers.
  remotes/origin/HEAD   -> origin/master
  remotes/origin/juno   1a08ea5 Fix the problem when an image is not located in the local docker image registry.
  remotes/origin/master 1ed1820 A note no firewall drivers.
# git checkout -b juno origin/juno
# python setup.py install
# systemctl start docker
# systemctl enable docker
# chmod 660  /var/run/docker.sock
#  mkdir /etc/nova/rootwrap.d

Glance works, busybox container stay in SPAWN for a while and goes to ERROR state.

The problem is that 

nova boot --image busybox --flavor m1.tiny --key-name osxkey busybox

basically runs the following

docker run busybox

and that will immediately exit since no tty and input will be associated with it. That is why you see

Cannot find any PID under container "31d9b2dced43413e4360a4b042c7bf74eaddb839b8f12657d535cfee90ef96e7"

Try some other images like mysql or sshd [1]. It should work then.

Thank you very much.

sshd one is not working with nova-docker plugin. I already tried it and although the image is booted, it is not booted as a docker instance so at the console no bootable device is shown. Any idea why the reason is?
