Re: [ansible-project] populating dictionary from lookup

[Gregory Edigarov]

Thank you, Vladimir. I've completely forgotten that ansible allows vars to
be defined for a single task.

The next option is putting the iteration into one task. For example,

- set_fact:
soarecords_dict: "{{ soarecords_dict|d({})|
 combine({item: _dict}) }}"
  loop: "{{ zones }}"
  vars:
_dict: "{{ dict(soafields|
   zip(lookup('dig', item, 'qtype=SOA')|split)) }}"

Create it in Jinja. For example,

soarecords: |
  {% for zone in zones %}
  {{ zone }}:
  {% for field in lookup('dig', zone, 'qtype=SOA')|split %}
{{ soafields[loop.index0] }}: {{ field }}
  {% endfor %}
  {% endfor %}
soarecords_dict: "{{ soarecords|from_yaml }}"

[ansible-project] populating dictionary from lookup

[gregory....@gmail.com]

Hello
As a part of another project, I have written a playbook:

---
- hosts: localhost
  vars:
tdict:
zones:
  - example.com
  - example.org
  - example.net
soafields:
  - nameserver
  - admin
  - serial
  - refresh
  - retry
  - expire
  - ttl
soarecords_dict:
  tasks:
- name: read soa record into dict
  set_fact:
tdict: "{{ tdict | combine( {item : 
lookup('dig',item,'qtype=SOA')|split } )}}"
  loop:
"{{ zones }}"

- debug:
msg: "{{ tdict.keys() | list }}"

- set_fact:
soarecords_dict: "{{ soarecords_dict | combine ({item : 
dict(soafields| zip(tdict[item]))}) }}"
  loop:
"{{ tdict.keys() |list }}"

- name: output soa records
  debug:
var: soarecords_dict

this works, but if possible, I want to get rid of temporary tdict part, 
meaning that I will set soarecords_dict variable directly from oneliner. 

doable?
