Molecule and Ansible details

Molecule installation method (one of):

• pip

Ansible installation method (one of):

• pip

Desired Behavior

http://molecule.readthedocs.io/en/latest/configuration.html#docker

The docker module docs seem to imply you have to install 'docker-py' in order for molecule to work.

'docker-py' is deprecated and has been replaced by the 'docker' pip module.

I was wondering what porting effort is required to drop 'docker-py' and use 'docker' instead?

I use molecule in a pex bundle with ansible, molecule, etc. I would prefer to include 'docker' instead of 'docker-py' in the pex bundle.

Thoughts?

Molecule doesn't have any docker code. It simply uses the Ansible docker modules. Basically, if it works with Ansible's docker container it will work with Molecule. Ansible appears to require docker-py.

There used to be strict dependency on docker-py, I think, but now ansible works just fine with docker, at least version 2.5. Guess docs just haven't been updated yet.

I remember reading some GitHub issue about ansible's docker support, but wasn't able to find it again.

Found this one instead, though:

You can have either docker or docker-py installed to use our modules. docker is preferred at this point.

However, you cannot have both python libraries installed at the same time.

Closing as not related to Molecule at this time.
