Configuration - PowerDNS Web UI

PowerDNS Web UI reads configuration from environment variables and an optional .env file in the working directory. CLI flags can override the listen host and port.

Environment variables

Variable	Default	Description
`PDNS_API_URL`	`http://localhost:8081`	Base URL of the PowerDNS Authoritative HTTP API
`PDNS_API_KEY`	`changeme`	API key sent to PowerDNS as `X-API-Key`
`PDNS_SERVER_ID`	`localhost`	PowerDNS server ID used in API paths
`HOST`	`0.0.0.0`	Interface the web UI listens on
`PORT`	`8080`	Port the web UI listens on

Example `.env`

PDNS_API_URL=http://127.0.0.1:8081
PDNS_API_KEY=replace-with-your-api-key
PDNS_SERVER_ID=localhost
HOST=127.0.0.1
PORT=8080

CLI flags

Flag	Description
`-host`	Host or interface to listen on
`-port`	Port to listen on
`-h`	Print help

Example:

pdns-webui -host 127.0.0.1 -port 8080

PowerDNS server ID

Most PowerDNS installations use localhost as the server ID. If your PowerDNS API uses a different server ID, set PDNS_SERVER_ID to match it.

Debug flag

.env.example also includes:

DEBUG=false

The current server code does not consume DEBUG. Treat it as reserved for development tooling rather than an application feature switch.
