Platinum Suite | Level 3 | Room 3-4

CoreDNS is a highly flexible and extensible DNS server widely recognized as the default DNS solution in Kubernetes. With its strong focus on service discovery, CoreDNS has gained popularity in various cloud-native environments. Its adaptability is largely driven by a plugin-based architecture, allowing developers to easily introduce new features and optimize performance at various levels. In this session, we will dive deep into CoreDNS’s extensive plugin ecosystem, examining several plugins that significantly enhance DNS scalability in Kubernetes. We’ll also walk through developing a Go-based demo plugin that leverages source IP for service discovery. Finally, we will look at the latest project updates and outline the roadmap for the CoreDNS community moving forward.
