Hi all,

Using the info from the document, I tried this but this totally does not work. I tried a few different varibles such as ansible\_ipv4 and nothing seemed to work.

{% for host in groups[‘iad2-ads’] %}  
server {{ inventory\_hostname }} {{ hostvars[host][‘ansible\_all\_ipv4\_address’] }}:80 check  
{% endfor %}

Output:

fatal: [iad2-lb2] =\> {‘msg’: “One or more undefined variables: ‘dict’ object has no attribute ‘ansible\_all\_ipv4\_address’”, ‘failed’: True}  
fatal: [iad2-lb2] =\> {‘msg’: “One or more undefined variables: ‘dict’ object has no attribute ‘ansible\_all\_ipv4\_address’”, ‘failed’: True}  
fatal: [iad2-lb3] =\> {‘msg’: “One or more undefined variables: ‘dict’ object has no attribute ‘ansible\_all\_ipv4\_address’”, ‘failed’: True}  
fatal: [iad2-lb3] =\> {‘msg’: “One or more undefined variables: ‘dict’ object has no attribute ‘ansible\_all\_ipv4\_address’”, ‘failed’: True}  
fatal: [iad2-lb4] =\> {‘msg’: “One or more undefined variables: ‘dict’ object has no attribute ‘ansible\_all\_ipv4\_address’”, ‘failed’: True}  
fatal: [iad2-lb4] =\> {‘msg’: “One or more undefined variables: ‘dict’ object has no attribute ‘ansible\_all\_ipv4\_address’”, ‘failed’: True}  
fatal: [iad2-lb1] =\> {‘msg’: “One or more undefined variables: ‘dict’ object has no attribute ‘ansible\_all\_ipv4\_address’”, ‘failed’: True}  
fatal: [iad2-lb1] =\> {‘msg’: “One or more undefined variables: ‘dict’ object has no attribute ‘ansible\_all\_ipv4\_address’”, ‘failed’: True}

FATAL: all hosts have already failed – aborting

Here is the output from module setup and it clearly show that this variable is available…

ansible iad2-ads -m setup |grep ansible\_all\_ipv4\_address  
“ansible\_all\_ipv4\_addresses”: [  
“ansible\_all\_ipv4\_addresses”: [

Please help.

Thanks,

Let's see what facts you do have ....

ansible -m setup -i \<inventory\_filename\> \<hostanme\> -a "filter=\*ipv4\*"

You have two different variable names there: ‘ansible\_all\_ipv4\_address’ and ‘ansible\_all\_ipv4\_addresses’.

Hi,

I definitely think that I found something wrong here:
