Hello,

I do run a playbook by setting a limit: ansible-playbook -i pilote.ini --limit DV70

My inventory file contains the following:

[DV70:chlidren]
DV70_DEV
DV70_REC
…
[DV70_DEV]
ansible_host=server1 ansible_user=usertest PARAM=WEB
ansible_host=server2 ansible_user=usertest PARAM=DATABASE

Is there a way in the playbook to gather in a variale the limit value , I would like to have a variable limit: DV70_DEV when I run the playbook on that host, hostvars would list all hosts.
In the same order, is there a way to have a variable with the name of the .ini file passed has a parameter with the -i option ?

Thanks for helping

I found inventory_file for the inventory variable.
About the groups, I tried without any success the following variables:
hostvars[inventory_hostname]
group_names
group

but i have the liste of al hosts, I want them separetly

inventory_hostname is the variable.
