Caching is mostly useful in a scenario when fetching data from the backend (upstream, database, etc.) is expensive. Cache will pass DNSSEC (DNSSEC OK; DO) options through the plugin for upstream queries. This plugin can only be used once per Server Block. Syntax cache [TTL] [ZONES...] TTL max TTL in seconds. If not specified, the maximum TTL will be used, which is 3600 for NOERROR responses and 1800 for denial of existence ones. https://coredns.io/explugins/k8s_cache/ Wed, 24 Apr 2024 15:20:00 +0200 https://coredns.io/explugins/k8s_cache/ Description This is a fork of cache. It adds an option to send a refreshed positive cache item first to pods with the label k8s-cache.coredns.io/early-refresh=true. Other pods get it only after a specified duration. This makes it possible to implement stable NetworkPolicy whitelists on the basis of domain names that are resolved with DNS, using Stable FQDNNetworkPolicies. The implementation uses an additional cache store called the “late cache”, which is shifted a number of seconds.
