Duplicated handlers when notifying by name with var

Archives Ansible Project

Hi,

I’m trying to notify handlers using vars in its name. If same role is called twice with diffferent vars - handlers start duplicating.

role1/handlers/main.yml

  • name: restart var1
    shell: echo restart var1

  • name: restart var2
    shell: echo restart var2

role1/tasks/main.yml

  • shell: echo hi
    notify:
  • restart {{ var }}

playbook.yml

  • hosts: localhost
    gather_facts: no
    roles:
  • role: role1
    var: var1
  • role: role1
    var: var2

Output I get:

I expect that each handler will be called only once. Having 3 role definitions will result in 9 notifications (3 per each handler)

Is that a bug or my configuration problem?

Well a handler could be parameterized, so … it depends.

We have talked about a way for the new role dependencies to require a role that could be included only once (by some intelligence built into the meta/ information in the role) that would allow you to require some_other role that defined the handler in one place.
