I've found a working one, it does work on another cluster, but doesn't work
in my environment.
Template:
{% for item in groups['nodes']-%}
{{ hostvars[item]['ansible_default_ipv4']['address'] }}
{% endfor %}
- hosts: opmon
tasks:
- name: Configure pg_hba
template:
src: test.j2
dest: /tmp/groups.txt
It works on another environment, but in my environment it goes fatal:
[xroad-a.itarchive.home]: FAILED! => {"changed": false, "msg":
"AnsibleUndefinedVariable: 'ansible.vars.hostvars.HostVarsVars object' has
no attribute 'ansible_default_ipv4'"}
