jerheij/powerdns repository overview

⁠Simple PowerDNS container with SQLite3 DB

⁠Sources

Base image: oraclelinux:8⁠
Software: PowerDNS⁠

⁠Requirements:

Working Docker installation.

⁠Usage

⁠Persistence

This PowerDNS uses an SQLite3 database (which is automatically created if it does not detect /pdns.db) as backend which means you need to make sure this database is persistent and not deleted when you delete the container. The database is located at /pdns.db. Start the container the first time and copy the database with the following command:

docker cp powerdns:/pdns.db ./pdns.db

Àfter this make sure to mount this database file on /pdns.db to keep using it with the following docker parameter:

docker run -v pdns.db:/pdns.db

You can also mount the database by adding the following file to your docker-compose yaml file:

volumes:
  - pdns.db:/pdns.db

⁠Docker-compose example

services:
  pdns:
    image: jerheij/powerdns:latest
    volumes:
      - ./pdns.db:/pdns.db

⁠Configuration

All the DNS records are saved in the SQLite3 database and can be added on the run by using the following command:

docker exec -ti powerdns pdnsutil

Read the pdnsutil documentation⁠ for more information about how to use the command.
