how to debug an ansible module

[Margin Hu]

Hi Guys, 

   how to debug an ansible module ?  I find http://docs.ansible.com/ansible/dev_guide/developing_modules.html, but  failed to run it as following.

how do you do testing when  develop one module ?

[root@server120 ansible-module]# ansible/hacking/test-module  -m ./kolla_docker.py
* including generated source, if any, saving to: /root/.ansible_module_generated
* ansiballz module detected; extracted module source to: /root/debug_dir

Hi Margin,

I usually use an IDE like PyCharm for this. I have detailed it here:
