Docker image for nsd, a static authoritative nameserver.
Create a zones directory. It will contain the zones data.
The example.com zone file will be zones/example.com.zone
The content of the zone file is a DNS zone respecting the standard Bind-Style Zone File Format. You'll find an example in this repository.
Build the container (if not pulled from docker hub)
# docker build -t nsd .
Start the container, binding your zones dir to the container's /etc/nsd/zones
dir and exposing the port 53 on tcp and udp. It will automatically generate
configuration files for the zones detected in the zones directory.
# docker run -d --name nsd -v $(pwd)/zones:/etc/nsd/zones:ro -p 53:53/udp -p 53:53 nsd
Check that it actually works (example files from this repo are used here):
# dig +short +norecurse test.example.com @localhost
10.0.0.1
If you make changes to the zones content, you can regenerate the config and reload nsd with this command:
# docker exec nsd nsd-reload
