How to stop a running python script by Ansible?

Question

In the node1 host, there is a Python script py_script.py :

import time

while True:

    print(time.strftime("%Y-%m-%d %H:%M:%S", time.localtime()))

    time.sleep(1)

then in my ansible host, I can use the ansible to start the script:

ansible node1 -m shell -a 'python py_script.py &'

then it will start running.

but how can I stop it?

Answer 1

It seems like you should have systemd manage your script or have some other kind of service.

If you do not want that, you can use pkill to kill this script:
pkill -f "python py_script.py"
This will kill all processes with the command python py_script.py .

You can do ansible node1 -m shell -a 'pkill -f "python py_script.py"'
