Ansible Nmap

Hello all

I have network 172.130.23.0/20 with a lot of router
I tried to make inventory file for ansible.

https://docs.ansible.com/ansible/latest/plugins/inventory/nmap.html

How can I use ansible nmap for scanning my network to make inventory file?

I google it, I didn’t find any

Thank you

The nmap inventory plugin does not create a file, it uses nmap every
time to generate the inventory in memory for ansible.

You can however use `ansible-inventory --list --yaml -i test.nmap.yml

inventory.yml` to generate a static inventory

it works with any plugin type, so you can do the same with a cloud
inventory and others.

contents of test.nmap.yml

    plugin: nmap
    strict: False
    address: 172.130.23..0/20

Hello Brain,

Sorry for late replay
I tried and got this error

ansible-inventory --list --yaml -i test.nmap.yml > inventory.yml
[WARNING]: * Failed to parse /Jaks/test.nmap.yml with yaml plugin: Plugin configuration YAML file,
not YAML inventory

file: nmap
[WARNING]: Unable to parse /Jaks/test.nmap.yml as an inventory source
[WARNING]: No inventory was parsed, only implicit localhost is available

and when I tried with -vvvv

ansible-inventory --list --yaml -i test.nmap.yml -vvvv

I tried edit /etc/ansible/ansible.cfg and add ini and auto in enable_plugins

Hello all

Sorry I just curious, is this normal result for plugin nmap?
