Hello,

I have a role which needs a dynamic handler.

I defined the handler in roles/foo/handlers/main.yml as:

- name: {{ item.name }}  
shell: docker restart {{ item.name }}  
listen: {{ item.name }}  
with\_items: “{{ config\_list }}”

When the task is notifying the handler I get the error:  
ERROR! The requested handler ‘name001’ was not found in either the main handlers list nor in the listening handlers list

1. Is my definition of the handler correct using with\_items?

2. How can I list listening handlers to see if the handler is even defined or not  
Thanks,

Komail
