Ansible - Variable Load ...

 1. Dynamic variable
We will create a variable file name same as os name and will use the variable name to configure
out target node.

How we can do it is by using defining a variable name with the os_name

1. I do have one control domain and 2 managed (Target) nodes.
a. Have one control node (AWS [ Free Tier] or Virtual Box)
b. Have one or 2 Managed nodes (AWS or Virtual Box [ Centos/amazon linux and ubuntu/debian)
Note: Keep your key safe.

2. Config file
# cat /etc/ansible/ansible.cfg
[defaults]
inventory=/root/myhosts
host_key_checking=false

[proviledge_escalation]
become=true

3. Inventory file
