getting 'play recap' changed variable from playbook

[Pieter Voet]

Hi all,

if any play in a  playbook actually changes something, I want to display a 'please restart something' message to the playbook user.

Is there a way to get the 'PLAY RECAP' changed  variable value from a playbook ?

something like this pseudo playbook:

---

- hosts: all

  tasks:

  - name: Do something

    shell: doit.sh

  - debug: msg="Please restart server to effectuate changes..."

    when: play_recap | Changed

I don't want a restart to get initiated from the playbook. The playbook should be used to possibly make a configuration change,

and when it did change something, the user should be notified to schedule the required restart later..

Wasn't able to find anything using on this using Google so far.. 

Thanks for any hints.

pieter.

I think the only way is to write you own callback plugin.

You could use a handler like so

---
- hosts: all
tasks:
- name: Do something
shell: doit.sh

notify: Inform user to reboot

handlers:
- name: Inform user to reboot

debug: msg="Please restart server to effectuate changes..."
