Docker container to run a secondary DNS Server on a Raspberry Pi (or anything ARM based)
docker build -t pi-secondary-dns .
Add your various zones to a zones.conf file (see example for examples)
docker run --rm -v $(pwd)/zones.conf:/etc/bind/zones.conf -p 53:53/tcp -p 53:53/udp pi-secondary-dns
- Docker doesn't play nice with IPv6 out of the box
