1. I have a requirement where I need to pass a hostname so that the ansible
playbook can take the hostname and do the necessary actions like stopping
and starting the service of a application.
How can I pass hostname that comes externally to the ansible playbook?
- hosts: all
gather_facts: true
tasks:
- name: Set services on job servers in {{ work_env }} to {{ work_op }}
service:
name: "{{ item }}"
state: "{{ work_op }}"
when:
- inventory_hostname in groups[work_env]
- inventory_hostname in groups["job"]
loop:
- rdcstop
- ratstop
loop_control:
label: Set {{ item }} service on {{ inventory_hostname }} to {{
work_op }}.
Here in the above work_env,work_op all are defined in my template. The
"job" is defined in my inventory file, this tells what host will fall under
the "jobs" category. So, if I remove the inventory file, how will ansible
will be able to read the hostname that comes from external calls?
