In the dynamic world of Kubernetes, efficient DNS resolution is critical for seamless application performance and scalability. CoreDNS, as the default DNS server for Kubernetes, offers flexible and high-performance DNS capabilities. This talk will delve into the lifecycle of a DNS request within a Kubernetes cluster using CoreDNS, offering insights into the flow of DNS traffic and enhancing your understanding of DNS requests and service discovery in Kubernetes—-key knowledge for effective debugging and issue resolution. Additionally, we will present a case study of Airbnb's successful integration of CoreDNS, highlighting the CoreDNS performance evaluation, our seamless migration approach, and scaling strategy. Finally, we will talk about the multi-cluster DNS resolution with CoreDNS. This section will demonstrate how multi-cluster DNS capabilities address the common challenges, discuss performance considerations and multi-cluster DNS limitations.
