How generate dynamic host file with only IP of concrete vendor (by MAC)

[Michal Šiman]

Hello to everybody. I would like run ansible playbook on all RPi (raspberry) in our network (at this moment we have around 300 pieces). All RPi have a IP dynamic from DHCP server. My idea is scann complete network found all live IP, get MAC of IP, filter only MAC with RPi vendor and from this IP create a list, dynamic host file. I have ansible on Linux for shure. What you recomend for quick solution? Nmap? Ping by sh from python? I all ready tried some solution but is too slow and non comfortable ... maybe somebody solving similar problem in history. Thx

Take a look at https://docs.ansible.com/ansible/latest/plugins/inventory/nmap.html

I'm using the following Playbook, which is taken the IP Address Entered from the Jenkins Pipeline:

---

  - name: Running Appened To Ansible Host File Playbook

    hosts: localhost

    connection: local

    tasks:

    - name: Adding The IP Address of the Newly Created Server to Ansible Host File

      blockinfile:

        path: /etc/ansible/hosts

        block: |

          [win]

          "{{ ip }}"

          [win:vars]

          ansible_user="{{ service }}"

          ansible_password="{{ service_pass}}"

          ansible_connection=winrm

          ansible_winrm_transport=credssp

          ansible_winrm_server_cert_validation=ignore
