--- title: "PowerDNS" date: 2019-03-03T16:39:46+01:00 draft: false slug: pdns --- <!-- THIS DOCUMENTATION IS AUTO-GENERATED. PLEASE DO NOT EDIT. --> <!-- providers/dns/pdns/pdns.toml --> <!-- THIS DOCUMENTATION IS AUTO-GENERATED. PLEASE DO NOT EDIT. --> Since: v0.4.0 Configuration for [PowerDNS](https://www.powerdns.com/). <!--more--> - Code: `pdns` Here is an example bash command using the PowerDNS provider: ```bash PDNS_API_URL=http://pdns-server:80/ \ PDNS_API_KEY=xxxx \ lego --email myemail@example.com --dns pdns --domains my.example.org run ``` ## Credentials | Environment Variable Name | Description | |-----------------------|-------------| | `PDNS_API_KEY` | API key | | `PDNS_API_URL` | API URL | The environment variable names can be suffixed by `_FILE` to reference a file instead of a value. More information [here](/lego/dns/#configuration-and-credentials). ## Additional Configuration | Environment Variable Name | Description | |--------------------------------|-------------| | `PDNS_HTTP_TIMEOUT` | API request timeout | | `PDNS_POLLING_INTERVAL` | Time between DNS propagation check | | `PDNS_PROPAGATION_TIMEOUT` | Maximum waiting time for DNS propagation | | `PDNS_SERVER_NAME` | Name of the server in the URL, 'localhost' by default | | `PDNS_TTL` | The TTL of the TXT record used for the DNS challenge | The environment variable names can be suffixed by `_FILE` to reference a file instead of a value. More information [here](/lego/dns/#configuration-and-credentials). ## Information Tested and confirmed to work with PowerDNS authoritative server 3.4.8 and 4.0.1. Refer to [PowerDNS documentation](https://doc.powerdns.com/md/httpapi/README/) instructions on how to enable the built-in API interface. PowerDNS Notes: - PowerDNS API does not currently support SSL, therefore you should take care to ensure that traffic between lego and the PowerDNS API is over a trusted network, VPN etc. - In order to have the SOA serial automatically increment each time the `_acme-challenge` record is added/modified via the API, set `SOA-EDIT-API` to `INCEPTION-INCREMENT` for the zone in the `domainmetadata` table ## More information - [API documentation](https://doc.powerdns.com/md/httpapi/README/) <!-- THIS DOCUMENTATION IS AUTO-GENERATED.
