API

The Python API is very powerful, and is how the ansible CLI and ansible-playbook are implemented.

It’s pretty simple:

import ansible.runner

runner = ansible.runner.Runner(
   module_name='ping',
   module_args='',
   pattern='web*',
   forks=10
)
datastructure = runner.run()

The run method returns results per host, grouped by whether they could be contacted or not. Return types are module specific, as expressed in the ‘ansible-modules’ documentation.:

{
    "dark" : {
       "web1.example.com" : "failure message"
    }
    "contacted" : {
       "web2.example.com" : 1
    }
}

A module can return any type of JSON data it wants, so Ansible can be used as a framework to rapidly build powerful applications and scripts.
