Ansible Python API: how to pass extra vars to playbook

Viewed 4656

I'm trying to use Python API to run some playbooks because I want to integrate it with Flash to enable the web-base control. Here is my playbook(crondis.yaml):

- hosts: "{{app_name}}-server"
  tasks:
    - name: disable cron
      cron:
        name: "{{app_name|upper}}_MONITOR"
        job: "/{{app_name}}/monitor.sh"
        disabled: yes

From cml that can be this way:

ansible-playbook --extra-vars="{'app_name': 'newapp'}" crondis.yaml

But in the Python API, I'm not seeing any place to add the vars to the play. I checked Variable_Manager, DataLoader and PlaybookExecutor but didn't find any function can add vars to the play. Please kindly shed a little bit light for me if you have any idea.

You can specify extra variables from within context.CLIARGS. You can specify a file by using @.

context.CLIARGS = ImmutableDict(connection='local', module_path=['/to/mymodules'], forks=10, become=None,
                            become_method=None, become_user=None, check=False, diff=False,
                            extra_vars={'@/path/to/vars/file', 'key=value'})
