Hello

I have a group of hosts with names like this:

[app01.spr.xxx.com](http://app01.spr.xxx.com)  
[app02.spr.xxx.com](http://app02.spr.xxx.com)  
…

[app10.spr.xxx.com](http://app10.spr.xxx.com)

For each host, there’s a setting (s) that should be set like this:

s=a01  
s=a02  
…  
s=a10

Since the values are similar and follow a pattern, what’s the smartest way to define them?

An obvious solution is to set a variable for each host, but i feel there’s a better way to do that.

TIA

You could do it like this in the play  
- set\_fact: s=a{{ inventory\_hostname.split('.')[0][-2:] }}

An alternative to inventory\_hostname is ansible\_hostname.
