Hi,

I have an inventory with groups this configuration the DB Servers:

[db]  
192.168.0.1  
192.168.0.2

192.168.0.3

I want to do loop the groups and get variable ipaddress in template.j2. My loop is:  
{% for host in groups[‘db’] -%}  
host all postgres {{ hostvars[host].ansible\_hostname }}/32 trust  
{% endfor %}

My error

“msg”: “AnsibleUndefinedVariable: ‘ansible.vars.hostvars.HostVarsVars object’ has no attribute ‘ansible\_hostname’”,

What`s correct configuration?

Hi  
remove hostvars[host].ansible\_hostname and try with hostvars[host].ansible\_facts.hostname if you are doing it from setup module or gayher\_facts

If it’s not fixed put your playbook here
