Intro: CoreDNS
summary
CoreDNS presents a plugin-based DNS server used as the default DNS in Kubernetes since 1.13 with version 1.1.5, about 150 maintainers and ~4,000 stars and 30 public adopters. It serves via Corefile configs and built-in plugins (>35) like kubernetes, file, forward, cache, Prometheus, rewrite and a node-local-cache DaemonSet that reduces central DNS load; sidecar caching is a working alternative. Upcoming work includes a resolver plugin, rate limiting and blocking of ANY queries.
