Run play books in remote server using python ansible runner

[Shasti]

Hi,

I am trying to automate script execution in remote servers using ansible/ansible play books. To start with I wanted to do a test, by invoking ansible runner to read IPs during runtime and touch a file or display a message in the remote host. I followed an example that found in a blog. 

Sample Python script. 

import ansible.runner
import ansible.playbook
import ansible.inventory
from ansible import callbacks
from ansible import utils
import json


def setup_inventory():
    """
    setting up the inventory

    set up a host
    :return:
    """

    example_host = ansible.inventory.Host(
        name='10.*.*.*,
        port=22
        )

    example_group = ansible.inventory.Group(
        name='sample_group_name'
    )
    example_group.add_host(example_host)
    example_inventory = ansible.inventory.Inventory()
    example_inventory.add_group(example_group)
    example_inventory.subset('sample_group_name')
    return example_inventory


def run_playbook():
    # set up Inventory
    example_inventory = setup_inventory()

    # setup callbacks
    stats = callbacks.AggregateStats()
    playbook_cb = callbacks.PlaybookCallbacks(verbose=utils.VERBOSITY)
    runner_cb = callbacks.PlaybookRunnerCallbacks(stats, verbose=utils.VERBOSITY)

    pb = ansible.playbook.PlayBook(
        playbook="test.yml",
        stats=stats,
        callbacks=playbook_cb,
        runner_callbacks=runner_cb,
        inventory=example_inventory,
        check=True
    )

    pr = pb.run()
    print json.dumps(pr, sort_keys=True, indent=4, separators=(',', ': '))

if __name__ == '__main__':
    run_playbook()

Sample test.yml playbook:

- hosts: sample_group_name

  user: username

  sudo: no

  tasks:

    # touch a file, using symbolic modes to set the permissions (equivalent to 0644)

    - debug: msg=“Ansible is great"

When is execute the py script, I am getting the below error. It looks like ansible can SSH to the box just fine, but not executing anything after that. I can run the playbook with out any issues in CLI. 

/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7 /app/ansible_run.py

PLAY [sample_group_name] ****************************************************** 

GATHERING FACTS *************************************************************** 

ok: [10.*.*.*]

TASK: [debug msg=“Ansible is great"] ******************************************* 

FATAL: no hosts matched or all hosts have already failed -- aborting

{

    “10.*.*.*: {

        "changed": 0,

        "failures": 0,

        "ok": 1,

        "skipped": 0,

        "unreachable": 0

    }

}

Process finished with exit code 0

Could someone point out what am I doing wrong here?

Thanks for your support & help.
