Please read the module documentation and install it 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` (Python >= 3.6) or `pip install docker==4.4.4` (Python 2.7) or `pip install docker-py` (Python 2.6). The error was: No module named 'docker'"

Did you simply follow the lines down there ? ie pip install docker ?

Then you need to install the collection using ansible-galaxy collection install community.docker
