Simple PowerDNS recursor container
Sources
Base image: oraclelinux:8
Software: PowerDNS
Requirements:
Working Docker installation.
Usage
Persistence
All the required configuration is already present so nothing is required for persistency. However; you can add a lot of custom parameters to the configurations files supported by the PowerDNS recursor. All configuration files in /etc/pdns-recursor/conf.d/ are loaded into the instance. To put custom configuration there simply mount a file as volume and put your extra configuration in there.
The docker-compose example below has a working configuration set to support RPZ through LUA.
