Install Ansible
===============
-- sudo apt update
-- sudo apt install ansible

to check
-- ansible --version

Connect ssh of target instance
===============================
Ways to do that
-------------------
-- ssh-copy-id 172.31.59.89
ssh and private id addresss
Easy way, But sometime it doesn't have full permissions

ssh-keygen 


ssh-rsa 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 ubuntu@ip-172-31-35-94



Steps to ansible with password less
================================
Create 2 servers 
1. Unbuntu Ansible ( Server )
2. Unbuntu ( Target )

Do ssh keygen in both server and target machines
---------------------------------------------------------
for targer --- create keys -- ssh keygen
and save in the notepad 
copy the generated key
from ansible server machine

Next: Go to targert ( Unbuntu)  and open authrized keys
.ssh folder
and paste it


Now go to target server details and find private ip
next: give ssh @private id in ansible server

--------------------------------------------------------------
Note: Public ip of ansible server to Authorized keys of target server

Any server same process
--------------------------------------------------------------
Inventary file: It is nothing but it stores IP's of target server
============================
Ansible adhoc commands
============================
==> ansible -i inventory 172.31.42.134 -- only for one server
==> ansible -i inventory all -- all the server's in inventory files
==> ansible -i inventory all -m "shell" -a "touch devopsclass"
