Hi  
I have a working play book in Ansible 1.9  
As part of it, I’m defining extra groups in file inventories/ec2/hosts, for example:

`

[us-west-2]  
[us\_west\_2:children]  
us-west-2

`

In Ansible 1.9, I used this group as follow:

1. run the playbook with -i inventories/ec2/ prefix

2. use the group as follow:

`

- debug: msg=“{{ hostvars[item].ec2\_private\_ip\_address }}”  
with\_items: groups.us\_west\_2

`

ec2.py did not change, and still return

`

…  
“us-west-2”: [  
“54.213.157.131”,  
“54.191.215.128”,  
“54.186.93.200”,  
“54.186.40.39”  
],  
…

`

Look like Ansible 2 does not use the groups defined in inventories/ec2/hosts.  
Is it bug or a feature?  
any idea how to bypass this issue?

Thanks  
Tzach

Is there a typo? Or are you using the group name as child element for  
another group? us-west-2 vs. us\_west\_2

What are the exact error messages? Maybe include some more debug tasks  
to output the values.

You had a debug task in your mail, what was the output and was did you  
expect to get?

If this worked in 1.9 and does no longer in 2.0, I would say try to  
test it in 2.1, as there have been lots of fixes for regressions  
AFAIK. If it still does not work, create a bug report aka issue on github.
