Ansible is an automation tool and for doing certain automation , 1st of all we have to give the proper information of our target node and this information is stored in some file and this file is known as "INVENTOTRY"

Here , I have created an inventory "ip.txt" and I had attached it on ANSIBLE CONFIGURATION FILE .

STEP 2 :

Now after adding our inventory to the ansible configuration file , then next step is the check the connectivity between Controller Node and Target Node .

For this we use a command

"ansible all -m ping"

After running the above command we get

which means We have successfully connected with our target node .

STEP 3 :

After connection now we have to write a playbook for ansible . for this first of all we have to make a workspace for it and here i made a folder "task1" and inside this folder i made a file with an extension of " .yml " and i named this file as "ansible_task.yml"
