inventory_groupname variable (similar to inventory_hostname)

[Darshan Shroff]

Ansible FAQ clarifies

"‘inventory_hostname’ is a magic variable that indicates the current host you are looping over in the host loop."

Is there a similar concept of inventory_groupname that can be made available to be used inside a playbook ?

e.g. If we are running a playbook in this manner

ansible-playbook -i inventory/prod site.yml --limit service_a

And 'prod' inventory is defined as below

[service_a]

host1

host2

[service_b]

host2

host3

Then is it feasible to reference the group name - service_a - inside site.yml in this manner -  {{ inventory_groupname }}

Unfortunately not.

You'll need to provide that with --extra-vars

ansible-playbook -i inventory/prod site.yml --limit service_a

--extra-vars mylimit=service_a


I think this should work so you don't have to specify both limit and mylimit

ansible-playbook -i inventory/prod site.yml -e mylimit=service_a

site.yml
---
- hosts: all:&{{ mylimit | default('all') }}
