I have a question; I’m experimenting with an Ansible playbook that I execute from a Flask application, and I want to capture the output logs in real-time and send them to my HTML using Socket.IO. I’ve tried things like setting quiet=False and playing with runner.events, but haven’t achieved any results he only send the logs after the playbook is done. I’m completely new to the Ansible Python story. Thx
