There is proper solution to this problem as of Ansible 2.2.
handlers can also “listen” to generic topics, and tasks can notify those topics as follows:
handlers:
- name: restart memcached
service: name=memcached state=restarted
listen: "restart web services"
- name: restart apache
service: name=apache state=restarted
listen: "restart web services"
tasks:
- name: restart everything
command: echo "this task will restart the web services"
notify: "restart web services"
This use makes it much easier to trigger multiple handlers. It also decouples handlers from their names, making it easier to share handlers among playbooks and roles
Specifically to the question, this should work:
- name: Check if restarted
shell: check_is_started.sh
register: result
listen: Restart processes
- name: Restart conditionally step 2
service: name=service state=restarted
when: result
listen: Restart processes
and in the task, notify handlers via ‘Restart processes’
