k, thanks.
I changed the name of the image in Glance because I wanted to prove to myself that zun/docker was pulling the image from Glance and not Docker Hub.

Hi Greg,
I created a bug to record the issue: https://bugs.launchpad.net/zun/+bug/1703955 . Due to this bug, Zun couldn’t find the docker image if the image was uploaded to glance under a different name. I think it will work if you can upload the image to glance with name “cirros”. For example:
$ docker pull cirros
$ docker save cirros | glance image-create --visibility public --container-format=docker --disk-format=raw --name cirros
$ zun run -i --name ctn-ping --image-driver glance cirros ping 8.8.8.8
Best regards,
Hongbin

Just tried this, this morning.
I can not launch a container when I specify to pull the container image from glance (instead of docker hub).
I get an error back from docker saying the “<imageName>:latest” can not be found.
I tried renaming the glance image to “<imageName>:latest” ... but that didn’t work either.
