Until recently, learning CoreDNS required reading the code or the skimpy documentation on the website. No longer. With this practical book, developers and operators working with Docker containers will understand how to use this standard DNS server with Kubernetes. John Belamaric, senior staff software engineer at Google, and Cricket Liu, Chief DNS Architect at Infoblox, show you how to configure CoreDNS using real-world configuration examples for achieving specific purposes. You’ll learn the basics of DNS, including how DNS functions as a location broker in container environments, and how it ties in to Kubernetes.
