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:

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

[akumar@ansible_node1 ~]$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.

After adding the following main task/action, before calling any other main tasks/actions or importing other yml file based tasks, worked!!
Basically the idea was to ensure state: forcereinstall is used while installing docker.
-- When this option was not used, Ansible's docker installation was showing ok: ... i.e. docker is already installed but then later, other actions where I used docker_* ansible modules, were still giving me the above no named module errors.
# If forcereinstall is removed, you may get an error i.e. no module found
#
- name: "Force Install 'docker' pip module" pip: name: docker extra_args: "--no-index --find-links={{ docker_SDK_Python_dest_path_where_I_see_bunch_of_whl_or_tar_gz_files }}" state: forcereinstall
