Hello All,

Please help or suggest how I can solve this problem.
I will pass 

-e group="1" when calling playbook.


*Playbook* - file.yml

hosts: servers_{{group}}

- task:
....
.....

*inventory*

[servers_grp1]
server1

[servers_grp2]
server2

....

[mainservers_1:children]  
[servers_grp1]
[servers_grp2]
[servers_grp3]
[servers_grp4]

[mainservers_2:children]  
[servers_grp5]
[servers_grp6]
[servers_grp7]
[servers_grp8]

In Jinja2 template file, I am trying to assign a value to variable 
"pod_num". But I am unable to get this

If (servers_grp1) is in mainservers_1
then 
pod_num = 2
else 
pod_num = 4



I tried a couple of things but did not work out.

{% if hosts is in groups[mainservers_1]
{% set pod_num = 2 %}

{% else %}
{% set pod_num = 4 %}


Thanks for helping and guiding.
