krazydns

a gokrazy appliance for the raspberry pi running coredns - the ultimate home dns setup.

why

the average techie's dns journey might look a little something like this (mine did):

1. use isp provided dns blissfully unaware
2. use google dns
3. use cloudflare dns
4. add a pihole
5. add a pihole with unbound as a resolver
6. add a pihole with unbound as a resolver and coredns for homelab zones
7. realize this could be all folded into coredns

and so i did! pihole - albeit an incredibly cool project - ended up being a bit too much hassle to maintain and was a bit annoying to deal with. after setting up coredns because i needed it for my homelab, i realized you could just have coredns do all of the things my frankenstein pihole appliance ended up doing. as a big bonus, this can be more lightweight, easily reproducible and defined by code using the awesome gokrazy project!

features

• lightweight gokrazy appliance that just bundles the linux kernel, go runtime and application code for coredns and it's configuration
• recursive dns resolution via the unbound plugin
• mdns hosting over regular dns via the mdns plugin
• dns-sinkhole-level ad blocking via the hosts plugin, not too dissimilar from how it works with pihole
• centralized metrics to prometheus via the prometheus plugin
• easy development, building and deployment via nix
