How do I exit Ansible play without error on a condition

Question

I want to exit without an error (I know about assert and fail modules) when I meet a certain condition. The following code exits but with a failure:

  tasks:

           


        

Answer 1

The following was helpful in my case, as meta: end_play seems to stop the execution for all hosts, not just the one that matches.

First establish a fact:

- name: Determine current version
  become: yes
  slurp:
    src: /opt/app/CHECKSUM
  register: version_check
  ignore_errors: yes

- set_fact:
  is_update_needed: "{{ ( version_check['checksum'] | b64decode != installer_file.stat.checksum)  }}"

Now include that part that should only executed on this condition:

# update-app.yml can be placed in the same role folder
- import_tasks: update-app.yml
  when: is_update_needed
