Deep Dive: CoreDNS

on YouTube ↗35m

" summary

CoreDNS is a flexible DNS server written in Go with a plugin-based architecture that registers via the Caddy-style plugin system; it claims Kubernetes integration (bundled for k8s 1.11), 100+ contributors, 16 maintainers and 29 public adopters. The demo builds a custom plugin that inspects the requester IP and returns 1.1.1.1 for 172.-range queries and 8.8.8.8 otherwise, creating A records in-memory and writing them back via the DNS response writer; plugin code is compiled into the CoreDNS binary.
