Hi,
I'm trying to write all IPs from all hosts to fil
this is my template:
{% for host in groups['all'] %}
{{ hostvars[host]['ansible_facts']['ansible_default_ipv4'] }}
{% endfor %}
and this is playbook
---
- name: update /etc/hosts file dynamically
hosts: all
gather_facts: yes
tasks:
- name: update /etc/hosts
template:
src: templates/allIPs.j2
dest: /tmp/allIPs
But when I run playbook and in template task I get AnsibleUndefinedVariable
error...
fatal: [node1]: FAILED! => {"changed": false, "msg":
"AnsibleUndefinedVariable: 'dict object' has no attribute
'ansible_default_ipv4'"}
fatal: [node2]: FAILED! => {"changed": false, "msg":
"AnsibleUndefinedVariable: 'dict object' has no attribute
'ansible_default_ipv4'"}
when I run ad-hoc setup module I get what I want:
node1| SUCCESS => {
"ansible_facts": {
"ansible_default_ipv4": {
"address": "172.31.116.92",
"alias": "ens5",
"broadcast": "172.31.127.255",
"gateway": "172.31.112.1",
"interface": "ens5",
"macaddress": "02:04:d5:9a:24:b4",
"mtu": 9001,
"netmask": "255.255.240.0",
"network": "172.31.112.0",
"type": "ether"
},
Do you have any idea what could be a problem?
