I’m running Ansible 1.4.4 which comes with Ubuntu 12.04 LTS. I’m getting weird results when trying to get host facts.

If I have:

- debug: var=hostvars[inventory\_hostname]

I get the all the information I’d expect, including:

ok: [test.example.com] =\> {  
&nbsp;&nbsp;&nbsp;"hostvars[inventory\_hostname]": {  
…  
"ansible\_eth0": {  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"active": true,  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"device": "eth0",  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"ipv4": {  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"address": “192.168.1.1",  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"netmask": "255.255.255.0",  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"network": “192.168.1.254"  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;},  
….

but if I have:

- debug: var=hostvars[inventory\_hostname]['ansible\_eth0’]

ok: [test.example.com] =\> {  
&nbsp;&nbsp;&nbsp;"hostvars[inventory\_hostname][ansible\_eth0]": "{{ hostvars[inventory\_hostname][ansible\_eth0] }}",  
&nbsp;&nbsp;&nbsp;"item": "”  
}

i.e. Nothing!

I also tried

- debug: msg={{hostvars[inventory\_hostname]['ansible\_eth0’]}}

and got the same result.

I did a google and didn’t find anything promising.

Any suggestions as to what I’m doing wrong?

Thanks,

GTG

Sorry, that doesn’t work:

fatal: [test.example.com] =\> {'msg': "One or more undefined variables: 'dict object' has no attribute 'ansible\_eth0'", 'failed': True}
