Question:
I have multiple tasks in a role as follows. I do not want to create another yml file to handle this task. I already have an include for the web servers, but a couple of our Perl servers require some web packages to be installed.

- name: Install PHP Modules command: with_dict: php_modules when: "'batch' in inventory_hostname" |
Note you’ll have a couple of skipped hosts during playbook run.
inventory_hostname is one of Ansible’s “magic” variables:
Additionally, inventory_hostname is the name of the hostname as
configured in Ansible’s inventory host file. This can be useful for
when you don’t want to rely on the discovered hostname
ansible_hostname or for other mysterious reasons. If you have a long
FQDN, inventory_hostname_short also contains the part up to the first
period, without the rest of the domain.
