Kubernetes 1.18 was recently released, and with it came a slew of super useful features! One feature that hit GA is node local caching. This allows each node in your cluster to cache DNS queries, reducing load on your primary in-cluster CoreDNS servers. Now that this feature is GA, I wanted to take it for a spin. If you’ve looked at the query logs on an active CoreDNS pod, or dealt with AWS DNS query limits, I’m sure you will appreciate the value this feature brings.
