unbound

Unbound on Alpine

Based on https://github.com/safelink-internet/unbound

Running

Use this command to start the container. Unbound will listen on port 53/udp.

docker run --name unbound -d -p 53:53/udp -p 53:53 registry.sdsys.ru/unbound

(optional) If you want to override the nameserver in the unbound container, you can use:

docker run --name unbound -d -p 53:53/udp -p 53:53 --dns="127.0.0.1" registry.sdsys.ru/unbound

If you want to add some local-zone or local-data, you can pass additional config:

docker run --name unbound -d -p 53:53/udp -v $(pwd)/local.conf:/etc/unbound/local-data.conf -p 53:53 registry.sdsys.ru/unbound
