This project includes two small modules to create reverse DNS records for Hetzner virtual servers.

Clone this repository and copy the modules from library/ to your Ansible project's library directory.

This module creates reverse DNS records through the Hetzner Cloud API1.

    - name: Create reverse DNS record (Hetzner Cloud)
      hcloud_rdns:
        token: MySecretToken
        ip: 192.0.2.23
        ptr: mail.example.com
      delegate_to: localhost

Delegation is not strictly necessary, but it prevents the token from leaving the control system.

This does not work for IPv6 addresses that do not already have a reverse DNS record. This may be a limitation in the API.

This module creates reverse DNS records through the Hetzner Robot Webservice2.

    - name: Create reverse DNS record (Hetzner Robot)
      hetzner_rdns:
        user: MyRobotWebserviceUsername
        password: MySecretPassword
        ip: 192.0.2.23
        ptr: mail.example.com
      delegate_to: localhost

As with the hcloud_rdns module, delegation is not required.

On success, both modules return the full response from the API. See the documentation (Cloud1, Robot2) for more information.
