Hello everybody,

I am writing a python script by Asible2.0 python api. My script work well when I just run a playbook by PlaybookCLI(). Currently, I want to add a callback with running the playbook, but the callback function is not work in PlaybookCLI(). Who know the reason? If I mistake to use the PlaybookCLI, how to change? Thanks for you.

My ansible version is 2.1. The below is my code and the myplaybook.yaml just do “/usr/bin/uptime” in target machines.

#!/usr/bin/env python

from ansible.cli.playbook import PlaybookCLI  
from ansible.plugins.callback import CallbackBase

class ResultCallback(CallbackBase):  
def v2\_runner\_on\_ok(self, result, \*\*kwargs):  
print(“this is my test”)  
host = result.\_host  
print json.dumps({host.name: result.\_result}, indent=4)

results\_callback = ResultCallback()  
my\_cli=PlaybookCLI([‘’, ‘/home/vagrant/myplaybook.yaml’, ‘-s’], callback=results\_callback)  
my\_cli.parse()  
results=my\_cli.run()
