Creating greater reliability: CoreDNS-nodecache

Ongoing issues in the Linux kernel's UDP connection tracking have caused well-documented challenges with DNS. Bugs particularly affect DNS in Kubernetes in its default configuration; we saw elevated rates of DNS timeouts that seemed to increase with load on our clusters. A Kubernetes extension called node-local helped alleviate some issues, but presented its own challenges. To solve the remaining problems, we developed a new implementation of node-local as a CoreDNS plugin: coreDNS-nodecache.

The designers and engineers planned for uncertainty. While we aren’t rocket scientists, we are designing a platform for an uncertain future. Contentful’s stable APIs, transformable webhooks, and extensibility features let us — and our customers — prepare for what’s next.
