I found a couple problems with the docker-py module. After I worked through them I ended up with this:

  - name: Docker-PY
    pip:
      name: "{{ item }}"
    with_items:
    - six==1.4
    - docker-py==1.1.0

First, I ran into your problem. The solution is to explicitly set the most recent version of six as described here: https://github.com/docker/docker-py/issues/344.

After that, I ran into an issue (you might run into it too) with a bug in the docker-py 1.2.2 version. The workaround is to specify an older version as described here: https://github.com/ansible/ansible-modules-core/issues/1227. Do a pip uninstall docker-py to get rid of the newer version.

If you aren't using ansible to install these then do this:

[sudo] pip uninstall docker-py
[sudo] pip install six==1.4
[sudo] pip install docker-py==1.1.0
