Folks, The following code is producing errors.


{% for v in hostvars.iteritems() %}
    {{ v['ansible_all_ipv4_addresses'][0] }}  {{ v['ansible_hostname'] }}
{% endfor %}


{'msg': "One or more undefined variables: 'tuple object' has no attribute 'ansible_all_ipv4_addresses'", 'failed': True}

What should this look like if i wanted an /etc/hosts file like: hostnameA hostnameB

Looking at the Error message

'tuple object' has no attribute 'ansible_all_ipv4_addresses'

, it is clear that your hosts' facts does not either contain ansible_all_ipv4_addresses inside where you were searching or syntax parser caught you off-guard :)

Let's try this:

{% for minion in groups['web'] %}
 {{ hostvars[minion]['ansible_all_ipv4_addresses'][0] }} {{ hostvars[minion]['ansible_hostname'] }}
{% endfor %}

Consider we lay out our inventory like this

[web] hostnameA hostnameB

Hope it solves your problem. Cheers !!

The issue is hostvars.iteritems()... switching to groups solved my problems. – CMag Dec 11 '13 at 15:30
Did something change? In 1.9.4 this fails: fatal: [data1]: FAILED! => {"changed": false, "failed": true, "msg": "AnsibleUndefinedVariable: 'dict object' has no attribute 'ansible_all_ipv4_addresses'"} – bbaassssiiee Apr 11 at 20:40
