I try to add a hos to my inventory with the command below:

ansible localhost -m add\_host -a “name=demo groups=containers”

This is the output:  
localhost | SUCCESS =\> {  
“add\_host”: {  
“groups”: [  
“containers”  
],  
“host\_name”: “demo”,  
“host\_vars”: {}  
},  
“changed”: true  
}

Unfortunately, Ansible doesn’t add the new host to my inventory file which is defined in /etc/ansible/ansible.cfg  
Also it doesn’t work when I add “-i /path/to/hosts” in the command.

Anyone suggestions? 🙂  
Thank you!

add\_host is meant to be used **runtime** thus it does not perform any operations making change persistent. Adding hosts to the inventory could be done via one of the “file” modules.
