pick the hostname dynamically from facts and match with inventory hostname and if matched then run the command

I’m looking for an idea to spill the hostname infromation geting from facts and run the command if the matches the hostname provided in inventory.
Saying that “myhostname” value should be picked & matched from inventory ones and get the IP of the hostname once matched to complete the command
My Host inventory:

test-host1
test-host2

somecommand hostinfo=myhostname:IP_ADDRESS <CMD_ARGS>
somecommand hostinfo=test-host1:xx.xx.xx.xx CIC01

Exaplaination:

somecommand = Static Value
hostinfo = Static Value
myhostname = Should be the same as taken from inventory
IP_ADDRESS = Should be the IP of Hostname taken from invetory
CMD_ARGS = Static Value ( like i mentioned CIC01)

  • name: Ansible to get the resolv.conf output
    hosts: all
    remote_user: root
    gather_facts: True
    tasks:
  • name: runing re-image
    shell: somecommand hostinfo=test-host1:xx.xx.xx.xx CIC01

register: named

  • name: Storing the remote Hosts Output locally
    lineinfile: create=yes dest=/opt/out.logs line=“{{ named.stdout }}”
    delegate_to: 127.0.0.1

A good start i this
https://docs.ansible.com/ansible/latest/playbooks_variables.html

My Host inventory:

test-host1
test-host2

Try running ansible ad-hoc to see what facts you have available
ansible test-host1 -m setup
and/or
ansible localhost -m setup

somecommand hostinfo=myhostname:IP_ADDRESS <CMD_ARGS>
somecommand hostinfo=test-host1:xx.xx.xx.xx CIC01

Exaplaination:

somecommand = Static Value
hostinfo = Static Value
myhostname = Should be the same as taken from inventory

{{ inventory_hostname }}

IP_ADDRESS = Should be the IP of Hostname taken from invetory

There are different once, check with the ad-hoc command above.
One is {{ ansible_default_ipv4.address }}
