Ansible task to stop service even if it doesn't exist

disable-service.yml

# This task will stop and disable a service without failing if the service does not exist.
# Requires Ansible 1.4 or newer.

# Update Dec 2016: Have rewritten this for the latest version of ansible and put conditions for both Ubuntu and CentOS

- name: "disable unused services"
  service: name={{item}} state=stopped enabled=no
  register: command_result
  failed_when: "unused_disable|failed and ('find' not in unused_disable.msg and 'found' not in unused_disable.msg)"
  with_items:
    - httpd
    - sendmail

NOTE: In Ansible v2.0 it'll be available must_exist option:

http://docs.ansible.com/ansible/service_module.html

It seams must_exist disappeared...

Is must_exist coming back? I was really excited about it.

Could also use must_exist ;)

works when i replace

register: command_result
by
register: unused_disable

thanks

Just for info - with Ansible v2.9 and later, you cannot use a jinja test as a filter. Consequently, to get this to work, replace unused_disable|failed with: unused_disable is failed

A combination of comments here got it working for me:

---
- name: Disable Metrics Utilites
  hosts: all
  tasks:
  - name: Stop and disable unused services
    service: name={{item}} state=stopped enabled=no
    register: unused_disable
    failed_when: "unused_disable is failed and ('find' not in unused_disable.msg and 'found' not in unused_disable.msg)"
    with_items:
      - metricbeat
      - auditbeat
      - telegraf
