How do I use a variable in an inventory file in a template

I have this inventory file



inventory/hosts_elk



<br>[elk-client-0]<br>10.11.22.22<br><br>



Now I have a template, and I want to do this



elk_server.yml.j2



<br>elk_server = {{ elk-client-0 }}<br><br>



But that doesn’t work, that is the value for {{ elk-client-0 }} does NOT get substituted.



What is the correct syntax so when the template gets laid out on the server, the resulting file looks like



<br>elk_server = 10.11.22.22<br><br>

Those aren’t variables.
You defined a group called ‘elk-client-0’ with a nameless server in it.

This template will produce the output you want:

elk_server = {{ groups['elk-client-0'][0] }}

Though I’m a bit confused why you have an elk server in a group called ‘elk-client-0’.

Thanks, that worked! It makes sense now.
