CoreDNS and Kubernetes John Belamaric, Principal Architect, Infoblox

What Is CoreDNS? http://coredns.io Flexible, extensible DNS server for Cloud Native Service Discovery From author of SkyDNS2, Miek Gieben Kubernetes integration for Service Discovery alternative to Kube- DNS Highly extensible via implementation of new middleware

Middleware Features enabled via middleware components Caching (negative and positive) Metrics (Prometheus) Proxy (query forwarding), Load balancing Logging Many more at https://github.com/miekg/coredns/tree/master/middleware Kubernetes middleware uses k8s API as data source Multiple data sources concurrently for different zones

Roadmap Service Registration & Discovery as in CNCF Architecture Short term: etcd middleware for dynamic registration with different zone Long term: offer a native registration function (maybe) Policy Engine for managing Service Registration & Discovery Extensible policies for security, rolling upgrades, telemetry-based load balancing and more Working on high-perf policy engine to open source in the future (anyone want to help?) Access data via REST, gRPC Mesos support What would you like to see?
