DNSControl: A DSL for DNS as Code from StackOverflow.com

Tuesday, March 14, 2017 - 11:55am12:50pm

Craig Peterson and Tom Limoncelli, Stack Overflow

Abstract: 

Introducing dnscontrol: the DNS DSL and compiler that lets StackOverflow.com treat DNS as code, with all the DevOps-y benefits of CI/CD, unit testing, and more. StackOverflow.com has a large and complex DNS configuration including many domains, complex CDN interactions, unavoidably repeated data, and more. The dnscontrol language permits us to specify our domains at a high level and leave the actual manipulations and updates to our automation. Massive changes, such as failovers between datacenters, are now a matter of changing a variable and recompiling. We've been able to address new problems with smart macros rather than manual updates. Dnscontrol is extendable and has plug-ins for BIND, CloudFlare, Route53/AWS, Azure, Google Cloud DNS, Name.Com, and more.
