Until recently, learning CoreDNS required reading the code or combing
through the skimpy documentation on the website. No longer. With this
practical book, developers and operators working with Docker or Linux
containers will learn 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 to achieve specific purposes.
You'll learn the basics of DNS, including how it functions as a location
broker in container environments and how it ties into Kubernetes.
- Dive into DNS theory: the DNS namespace, domain names, domains, and
zones
- Learn how to configure your CoreDNS server
- Manage and serve basic and advanced zone data with CoreDNS
- Configure CoreDNS service discovery with etcd and Kubernetes
- Learn one of the most common use cases for CoreDNS: the integration
with Kubernetes
- Manipulate queries and responses as they flow through the plug-in
chain
- Monitor and troubleshoot the availability and performance of your DNS
service
- Build custom versions of CoreDNS and write your own plug-ins
