Hi Guys,

Hi@akhtar,

Handlers are just like normal tasks in an Ansible playbook but they run only when if the Task contains a “notify” directive. It also indicates that it changed something. I have attached one example below.

- name: webserver
  hosts: WORKSPACE
  tasks:
         - name: Install nginx
           package:
             name: nginx
             state: present
           notify:
                Start nginx
  handlers:
       - name: Start nginx
         service:
           name: nginx
           state: started
