(Not really your fault, also filing the same issue against ansible)

Yeah, that's on ansible, unfortunately. https://github.com/ansible/ansible/blob/devel/lib/ansible/module_utils/docker_common.py#L154

The docker module has had a version_info for a while now (since 1.2), so there's no excuse for not using it.

I'm gonna close this since the issue is downstream, but feel free to ping me here if there's anything I can do to help.
