[ansible@ip-172-31-36-60 ~]$ sudo vi /etc/ansible/hosts
[webservers]
172.31.90.234

Now test it.

How to run ansible by using custom inventory file in place of default inventory file(/etc/ansible/hosts

)

Step 1:-  Comment the line in default inventory file(/etc/ansible/hosts)

[ansible@ip-172-31-36-60 ~]$ sudo vi /etc/ansible/hosts

#[webservers]

#172.31.90.234

Step 2: create own custom inventory file( name you can give any thing)

[ansible@ip-172-31-36-60 ~]$ vi inventory.txt

[ansible@ip-172-31-36-60 ~]$ cat inventory.txt

[webservers]

172.31.90.234

Now test it:-

[ansible@ip-172-31-36-60 ~]$ ansible all -m ping -i inventory.txt

172.31.90.234 | SUCCESS => {

    "changed": false,

    "ping": "pong"

}

You can also use the below option

[ansible@ip-172-31-36-60 ~]$ ansible webservers -m ping -i inventory.txt

172.31.90.234 | SUCCESS => {

    "changed": false,

    "ping": "pong"

}

[ansible@ip-172-31-36-60 ~]$ ansible webservers* -m ping -i inventory.txt

172.31.90.234 | SUCCESS => {

    "changed": false,

    "ping": "pong"

}

[ansible@ip-172-31-36-60 ~]$ ansible webserve* -m ping -i inventory.txt

172.31.90.234 | SUCCESS => {

    "changed": false,

    "ping": "pong"

}

[ansible@ip-172-31-36-60 ~]$ ansible 172.31.90.234 -m ping -i inventory.txt

172.31.90.234 | SUCCESS => {

    "changed": false,

    "ping": "pong"

}

[ansible@ip-172-31-36-60 ~]$
