Ansible - Python - Docker: Module Not Found Docker / Docker-Py — Why No Module Found Error Is Coming in Python Prompt and in Ansible

Ansible 2.8.3

When I run my playbook, I see the following error.

TASK [deployer_role : Creating network] ***************************************************************************************************************************************************************************
fatal: [ansible_node01.company.server.com]: FAILED! => {"changed": false, "msg": "Failed to import the required Python library (Docker SDK for Python: docker (Python >= 2.7) or docker-py (Python 2.6)) on ans's Python /usr/bin/python. Please read module documentation and install in the appropriate location, for example via `pip install docker` or `pip install docker-py` (Python 2.6). The error was: No module named requests (or urllib3 or etc was coming..)

Task action is:

- name: Creating volumes
  docker_volume:
    name: "{{ item }}"
  with_items:
    - bbdb-data
    - bb-data

On the machine, it shows the required pip modules are installed for Python 2.7.5.

NOTE: I'm not using or have Python3 not sure why I'm getting No module found error when everything is installed.

I have tried passing: --extra-vars "ansible_python_interpreter=/usr/bin/python2.7 to no luck.

On target node, Folder/File permission on /usr/lib/python2.7/site-packages or /usr/lib64/python2.7/site-packages is 655 or 775 (Tried both) to no luck.

Adding - pip: { name: docker, state: present } before - name: "Creating volumes" ... task, shows Requirements already satisfied for the required pip modules lilke docker etc and they are installed, but the next one for creating docker_volume or any use of ansible docker_* module fails with No module found for either docker or urllib3 or requests

They are all present (if I do pip list or - pip: { name: <pip_module>, state: present } in Ansible.

root user's umask is 0027 on both the ansible control and the target node machines.
