CoreDNS

CoreDNS is a cloud native, authoritative DNS server written in Go. It provides dynamic service discovery backed by different data sources, including etcd and Kubernetes. It serves as a simple, flexible DNS server in both cloud-native and traditional environments.

DNS-over-QUIC (DoQ) and DNS-over-HTTP/3 (DoH3) are relatively new protocols for transmitting DNS queries with security and privacy. Additionally, DoQ and DoH3 also offers other benefits such as improved latency and better error detection. The goal of this proposal is to add DoQ and/or DoH3 support to CoreDNS. Expected Outcome: An implementation of DoQ or DoH3 for CoreDNS. A stretch goal of adding both DoQ and DoH3 is also within scope. - Recommended Skills: Golang, DNS. - Mentor(s): Yong Tang @yongtang (yong.tang.github@outlook.com); Chris O'Haver @chrisohaver (cohaver@infoblox.com) - Upstream Issue (URL): https://github.com/coredns/coredns/issues/5583, https://github.com/coredns/coredns/issues/5539

CoreDNS (https://github.com/coredns/coredns) is a cloud-native DNS server with a focus on service discovery. While best known as the default DNS server for Kubernetes, CoreDNS is capable of handle many other scenarios within or outside of Kubernetes clusters to make easy infrastructure management. One such case is certificate management. This project is to provide ACME protocol support so that it is possible to have automatic certificate management through CoreDNS.
