Fails to perform docker pull via ansible

HOST

• Ubuntu 19.10
• Ansible 2.9.9 (latest)
• Mitogen 0.2.9 (latest)
• Python 3.7.5
• ansible-config dump --only-changed yields an empty file
• Nothing custom

TARGET

• Ubuntu 18.04
• Python ? There are multiple versions on the target machine, so I ran ansible -m setup machinename and it showed me "ansible_python_version": "2.7.17". I hope that’s right?

PROBLEM

In a playbook:

- name: pull image
  docker_image:
    name: imagename:v1.2.3
    source: pull

Error:

“msg”: “Failed to import the required Python library (Docker SDK for Python: docker (Python >= 2.7) or docker-py (Python 2.6)) on remote’s Python /usr/bin/python. Please read module documentation and install in the appropriate location. If the required library is installed, but Ansible is using the wrong Python interpreter, please consult the documentation on ansible_python_interpreter, for example via pip install docker or pip install docker-py (Python 2.6). The error was: u’requests’ is present in the Mitogen importer blacklist, therefore this context will not attempt to request it from the master, as the request will always be refused.”

This is part of a very large playbook which seems to work, only this task fails. And without mitogen this task works.

I have no idea what the problem could be?

There’s a new rc now for Ansible 2.10+: https://github.com/dw/mitogen/releases/tag/v0.3.0-rc.0

Perf on Python3 is not yet as good as Python2, but eventually the plan is to fix that up 👍
