" summary

CoreDNS is a plugin-first DNS server used as Kubernetes’ default since 1.13 and released 1.8.0 (Oct 22, 2020) which adds transfer, local and minimal plugins; it supports DNS-over-gRPC and cloud backends (Route53, Azure, Google). The demo builds a custom binary by adding demo:demo to plugin.cfg and go building, and a tiny plugin returns 1.1.1.1 for sources starting with 172 or 127 and 8.8.8.8 otherwise — the build and runtime behavior work as shown. Community size: 307 contributors, 26 maintainers, 8,000 stars.
