parameterized first found

[vadimv Vatlin]

This code works with ansible 1.9.4

- name: Configure user parameters
  template: src={{ lookup('first_found', [ 'userparameter_' + item + '_' + ansible_pkg_mgr + '.j2', 'userparameter_' + item + '.j2' ]) }} dest=/etc/zabbix/zabbix_agentd.d/userparameter_{{ item }}.conf
  with_items: "{{ zabbixagent_userparameters }}"
  when: zabbixagent_userparameters is defined
  notify:
    - restart zabbix-agent

But not working with 2.0.0.1

What I do wrong ?  

[Brian Coca]

the lookup is returning a list, not a string, as a workaround:

template: src={{ lookup('first_found', [ 'userparameter_' + item +

'_' + ansible_pkg_mgr + '.j2', 'userparameter_' + item + '.j2' ])[0]
}}

[vadimv Vatlin]

thank you very much. 

is it make any sense that first_found return a list ?

i think that _first_ means that list will always contain 1 element.

[Brian Coca]

looking into that, for most lookups the answer is 'yes', in this case
it can be considered a bug, you should open an issue in github.
