I am trying to iterate over a hash of hash of a list, but I do not seem to be having much luck, I have setup a group variable which I select using a variable, which appears to be working correctly as per the debug, but once in the template I don’t seem to be able to iterate over it no matter what permutations I use.

Any advice on this would be great.  
Thanks  
Dave

**cat group\_vars/all**  
boston:  
nameservers: [‘10.0.0.1’,‘10.0.0.2’]  
ntp: [‘[pool1.ntp.org](http://pool1.ntp.org)’,‘[pool2.ntp.org](http://pool2.ntp.org)’]  
losangeles:  
nameservers: [‘10.0.1.1’,‘10.0.1.2’]  
ntp: [‘[pool1.ntp.org](http://pool1.ntp.org)’,‘[pool2.ntp.org](http://pool2.ntp.org)’]

I managed to achieve this by using “hostvar” in my template is this the correct way to be referencing hashes in templates?

Thanks  
Dave

{% for servers in hostvars[inventory\_hostname][SITE][‘ntp’] %}  
server {{servers}}  
{% endfor %}
