Hi all,

This seems to only happen with a vlan on top of a bond device.

The fact gathers the nic properly:

pouet1 | success \>\> {  
“ansible\_facts”: {  
“ansible\_bond1.2108”: {  
“active”: true,  
“device”: “bond1.2108”,  
“ipv4”: {  
“address”: “192.168.0.1”,  
“netmask”: “255.255.255.0”,  
“network”: “192.168.0.0”  
},  
“ipv6”: [  
{  
“address”: “fe80::b6b5:2fff:fe63:4e69”,  
“prefix”: “64”,  
“scope”: “link”  
}  
],  
“macaddress”: “b4:b5:2f:25:6e:90”,  
“mtu”: 1500,  
“promisc”: false,  
“type”: “ether”  
}  
},  
“changed”: false  
}

However while trying to use this variable inside a playbook like this:

- name: tell memcached what IP to listen on  
lineinfile: dest=/etc/memcached.conf regexp=“^-l” line=‘-l {{ ansible\_bond1.2108.ipv4.address }}’  
notify: restart memcached

I get the following in the memcached.conf:

-l {{ansible\_bond1.2108.ipv4.address}}

I’ve tried with another nic such as eth0 and it works like a charm.  
Am I hitting a bug?

Thanksin advance!

This is a question about variables with ‘illegal’ characters in them not being able to be accessed in short form.

I believe I also discussed this on GitHub previously, though the solution is just:

-l {{ hostvars[inventory\_hostname][“ansible\_bond1.2108”].ipv4.address }}

I believe I also left the ticket open and suggested we replace “.” with “\_” so it allows the fact to be accessed directly, though this would be a backwards incompatible change for those that had dots in interface names – it’s easier than needing to know the above.

Yes we discussed that on Github as well.  
Thanks again Michael!
