docker-powerdns
PowerDNS docker container, based on Debian Jessie.
Requirements
Docker
To use this image you need docker daemon installed. Run the following commands as root:
curl -ssl https://get.docker.com | sh
Docker-compose
Docker-compose is desirable (run as root as well):
curl -L https://github.com/docker/compose/releases/download/1.7.1/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
Docker-compose Example
Save the following snippet as docker-compose.yaml in any folder you like, or clone this repository, which contains the same file.
pdns:
image: interlegis/powerdns:4.0.1-1
links:
- "mysql:mysql"
ports:
- "53:53"
- "53:53/udp"
- "8088:8081"
environment:
- PDNSCONF_API_KEY=a_strong_api_key
- PDNSCONF_MASTER=yes
- PDNSCONF_DEFAULT_SOA_NAME=dnsserver.domain.com
mysql:
image: mysql
environment:
- MYSQL_ROOT_PASSWORD=mysqlrootpw
- MYSQL_DATABASE=pdns
- MYSQL_USER=pdns
- MYSQL_PASSWORD=pdnspw
Environment Variables Supported
Any setting from https://doc.powerdns.com/3/authoritative/settings/ is supported. Just add the prefix "PDNS_" and replace any hyphens (-) with underscore (_). Example:
allow-axfr-ips ===> PDNS_ALLOW_AXFR_IPS
Additional Environment Variables:
- SECALLZONES_CRONJOB: If set to 'yes', a Cron Job every half hour checks if any domain is not DNSSEC enabled. If so, it enables DNSSEC for that zone and fixes any DS records in parent zones hosted in the same server.
Clustering
You can easily enable PowerDNS native "slaves" with bitnami/mariadb docker image. See https://hub.docker.com/r/bitnami/mariadb
Running
cd <folder where docker-compose.yaml is>
docker-compose up -d
