I have successfully setup devstack with Magnum,
following this link https://github.com/openstack/magnum/blob/master/doc/source/dev/quickstart.rst#building-and-using-a-swarm-bay
I created a Docker-Swarm bay and successfully launched a simple container.
What is the behavior of MAGNUM wrt downloading of Container-formatted Images in Glance to the COE ?
e.g. in the setup from the above link
gwaines at wildcat-76:~$ glance -v image-list

Does MAGNUM automatically download all Glance Images of a particular Container Format to the COE ?
In the above setup, which Glance Image does the ‘docker image’ “cirros” correspond to ?
Greg.
