I've tried the second version locally, it works fine for me (well, I've
been testing with the ubuntu:trusty image but that doesn't change the
syntax).
The first one gives me a syntax error, but replacing the volumes line
with: volumes: "{{theVolumes|default([])|join(',')}}" fixes it.
What versions of ansible/docker/docker-py are you using? Have you tried
with the latest releases?
