    - name: Example task
      command: whoami
      notify: whoami_handler
  handlers:

      debug:
        msg: "Whoami was called on {{ inventory_hostname }}"

Tip

Handlers are special tasks, which are always run at the end of a playbook. They are called by the notify directive. They are often used to perform post-installation modifications eg. starting of services, editing configuration files.
