Hi,

(Disclaimer: I’m very new to ansible so I easily might miss something very straightforward.)

I have a number of sites, e.g. site1, site2, …, siteN. Each site has a number of machines that play a particular “role”, e.g. roleA1, roleA2, roleB1, roleC1, …

I easily created an inventory for sites:

[siteX]  
[roleA1.siteX.example.com](http://roleA1.siteX.example.com)  
…

However I could not find a way to have a special group for all available roleY machines. I tried

[roleY]  
roleY[1:9].\*.example.com

but the result was not what I expected.

Any suggestions on what I should read to better understand how the things work?

the wildcard won’t work, but you can add another range:

roleY[1:9].site[1:9].[example.com](http://example.com)

Thanks, Brian.

As we discussed today on IRC:

20:54 my site names are 0000 … 9999 (not that many yet, but they grow :))  
20:54 so i’d specify [0000:9999]?  
20:54 [0000:9999]  
20:54 yep  
20:55 interesting: it’s so simple 🙂 meanwhile i wrote a dynamic inventory 🙂  
20:57 ah…  
20:58 i just realised: the example i gave in the post, is not totally accurate ☹  
20:59 the host name looks like roleX.siteYYYY...example.com  
21:00 where is geographical area (can be 0-2 components), and is either “test” (where is not present) or “prod” (where is 1-2 name components)  
21:00 bcoca: do you think i could use ranges in this case as well?  
21:01 not sure

So, I will stick to my dynamic inventory script for now.
