Hi,

I am using Ansible v1.7.1.

I am having trouble using the gathered facts when an interface has bonding and VLANs enabled:

# ansible -m setup testserver

[…]

“ansible\_bond0.11”: {  
“active”: true,  
“device”: “bond0.11”,  
“ipv4”: {  
“address”: “192.168.11.66”,  
“netmask”: “255.255.255.0”,  
“network”: “192.168.11.0”  
},  
“macaddress”: “d4:ae:52:98:71:1f”,  
“mtu”: 1500,  
“promisc”: false,  
“type”: “ether”  
},

[…]

Then, I have a playbook that sets a variable:

Example from a different server that doesn’t have bonding or VLANs:

listen\_ip: “{{ ansible\_eth1.ipv4.address }}”

Example that doesn’t work:

listen\_ip: “{{ ansible\_bond0.11.ipv4.address }}”

Ansible output:

fatal: [testserver] =\> {‘msg’: ‘AnsibleUndefinedVariable: One or more undefined variables: dict object has no element 11’, ‘failed’: True}  
fatal: [testserver] =\> {‘msg’: ‘AnsibleUndefinedVariable: One or more undefined variables: dict object has no element 11’, ‘failed’: True}

FATAL: all hosts have already failed – aborting

I have tried different possibilities but they all failed:

“{{ ansible\_bond0.11.ipv4.address }}”

“{{ ansible\_bond0\.11.ipv4.address }}”

“{{ [ansible\_bond0.11].ipv4.address }}”

“{{ {ansible\_bond0.11}.ipv4.address }}”

“{{ ‘ansible\_bond0.11’.ipv4.address }}”

I think Ansible is taking the VLAN tag as part of the subgroup in the config…

What is the correct way of selecting the IPv4 address of a bond0.11 interface?

Thank you in advanced.

Best regards,  
J.

To use a hostvar that contains a ‘.’ you will need to do something such as:

{{ hostvars[inventory\_hostname][‘ansible\_bond0.11’][‘ipv4’][‘address’] }}

Hi Matt,

Would this be valid?

"{{ hostvars[{{ ansible\_host }}]['ansible\_bond0.11']['ipv4']['address'] }}"

This is the playbook:

> > “{{ hostvars[{{ ansible\_host }}][‘ansible\_bond0.11’][‘ipv4’][‘address’] }}”

You’ll want to remove the template stuff inside the template stuff:

“{{ hostvars[ansible\_host][‘ansible\_bond0.11’][‘ipv4’][‘address’] }}”

Hi Michael,

Just tried, same problem…

“{{ hostvars[ansible\_host][‘ansible\_bond0.11’][‘ipv4’][‘address’] }}”:

fatal: [testserver1] =\> {‘msg’: “AnsibleUndefinedVariable: One or more undefined variables: ‘ansible\_host’ is undefined”, ‘failed’: True}  
fatal: [testserver1] =\> {‘msg’: “AnsibleUndefinedVariable: One or more undefined variables: ‘ansible\_host’ is undefined”, ‘failed’: True}

fatal: [testserver2] =\> {‘msg’: “AnsibleUndefinedVariable: One or more undefined variables: ‘ansible\_host’ is undefined”, ‘failed’: True}  
fatal: [testserver2] =\> {‘msg’: “AnsibleUndefinedVariable: One or more undefined variables: ‘ansible\_host’ is undefined”, ‘failed’: True}

FATAL: all hosts have already failed – aborting

Just in case, tried this one also:

“{{ hostvars[‘ansible\_host’][‘ansible\_bond0.11’][‘ipv4’][‘address’] }}”

fatal: [testserver1] =\> {‘msg’: ‘AnsibleError: host not found: ansible\_host’, ‘failed’: True}  
fatal: [testserver1] =\> {‘msg’: ‘AnsibleError: host not found: ansible\_host’, ‘failed’: True}

fatal: [testserver2] =\> {‘msg’: ‘AnsibleError: host not found: ansible\_host’, ‘failed’: True}  
fatal: [testserver2] =\> {‘msg’: ‘AnsibleError: host not found: ansible\_host’, ‘failed’: True}

FATAL: all hosts have already failed – aborting

Any other ideas?

Thank you!

J.

According to that error, you have not defined a variable called ‘ansible\_host’. Where is that variable supposed to be coming from?

The variable that ansible creates that references the current host is called inventory\_hostname. Perhaps you were meaning ansible\_hostname?

In either case inventory\_hostname is safer to use, as that is what ansible knows about from the inventory, and ansible\_hostname is not necessarily the same value as inventory\_hostname.

Hi Matt,

I just wanted to say that it worked perfectly as you said.

The correct format is:

“{{ hostvars[inventory\_hostname][‘ansible\_bond0.11’][‘ipv4’][‘address’] }}”

Thank you very much.
