A docker based nsd testbed
A simple docker based nsd testbed.
This is not intended to be used in a production setup.
Just run make to build and run the testbed on your computer.
After that you can send queries to the server like this:
$ dig SOA example.com @127.0.0.1 -p 8053
By default the files from the ./config/ directory are mounted into the docker container.
Zonefiles reside in the ./config/zonefiles/ directory.
If you want to make changes to the config (./config/nsd.conf) or any of the zones just edit the files in your working directory and then save it.
The scripts ./scripts/watch-nsd-config and ./scripts/watch-zonefiles are used to watch for modifications on the respective files.
They use the nsd-checkconf and nsd-checkzone binaries to make sure that your changes are valid.
