Quit a playbook without error for a particular host

[isor...@gmail.com]

Hi, 

I have a playbook containing several Plays and each Play is executed on a bunch of hosts. 

I would like to quit the whole playbook (not only the current play) for a particular host if a  "when: condition" is met. 

Example Playbook with 2 Plays: 

- name: Play for patching precheck and download updates

  hosts: patchgroup

  remote_user: ansible

  gather_facts: true

  become: true

  timeout: 300

  roles:

    - patching_precheck_download

- name: Play for setting Icinga downtime

  hosts: patchgroup

  remote_user: ansible

  gather_facts: true

  roles:

    - role: icinga_downtime

      vars:

        host_and_services: true

In the role patching_precheck_download there is the following task

- block:

    - name: Red Hat | Quit playbook when no updates are found

      fail:

        msg: "Quit playbook for the current host since no updates are found."

    #- meta: end_host

  when: updates.stdout_lines | length == 0

If the when condition is met, I currently use "fail" which will end for the particular host, both the current play and the playbook. This is intended, but it will throw an error which should not be the case. 

The other alternative I found is "meta: end_host" this will not throw an error and end the play for the current host, but not for the whole Playbook (2nd Play will still be executed for this particular host). So, this is no solution. 

Any ideas how to quit a Play and Playbook without throwing an error ?

Many thanks

Perhaps one solution is to set some fact (with set_fact) when this condition is met, like `finished: yes` and for subsequent plays/tasks you can add a line `when: finished is not defined`. Facts are set on a per-host basis, so I think this should work.

This isn't really quitting, but it achieves the same result by skipping those tasks.
