Ah ha! Got it, looks like there are instances where the Docker API does funny things. Let me put up a fix... Thanks @randyzwitch!

Thanks for reporting this, @randyzwitch! I've heard this happen to a couple of people, but can't seem to repro myself. If your machine still exhibits this, any chance you can try running the following to help me narrow down the bug?

docker run -it --entrypoint=bash -v /var/run/docker.sock:/var/run/docker.sock cloudera/clusterdock

This will open a Bash shell within the clusterdock container. At this point,
open a python interpreter by typing python and hitting enter. Then type the following:

from docker import Client
client = Client()
for image in client.images():
  print image

Does that behave? Go through without any exceptions being raised? If so, in the same interpreter, try the following:

for image in client.images():
  for tag in image['RepoTags']:
    print tag

Let me know if you can give it a shot.

The problem is in the second snippet:

>>> for image in client.images():
...     print image['RepoTags']
... 
[u'cloudera/clusterdock:latest']
None
[u'cloudera/clusterdock:cdh580_cm581_secondary-node']
[u'cloudera/clusterdock:cdh580_cm581_primary-node']
[u'hortonworks/ambari-server:latest']
[u'hortonworks/ambari-agent:latest']
[u'nginx:latest']
[u'sequenceiq/consul:v0.5.0-v6']
[u'sequenceiq/ambari:1.7.0']
[u'sequenceiq/ambari:1.6.0']

Here's this if it helps, you can see which one has the u'RepoTags': None, in it

Just pushed an updated image, @randyzwitch. Can you give it a try to see if it fixed the issue? (Just rerun the command as before. The clusterdock helper script automatically pulls down new images.)

Yes, that fixed it, thanks!
