NodeLocal DNSCache 通过在集群节点上作为 DaemonSet 运行 dns 缓存代理来提高集群 DNS 性能。
在当今的体系结构中，处于 ClusterFirst DNS 模式的 Pod 可以连接到 kube-dns serviceIP 进行 DNS 查询。
通过 kube-proxy 添加的 iptables 规则将其转换为 kube-dns/CoreDNS 端点。
借助这种新架构，Pods 将可以访问在同一节点上运行的 dns 缓存代理，从而避免了 iptables DNAT 规则和连接跟踪。

本地缓存代理将查询 kube-dns 服务以获取集群主机名的缓存缺失（默认为 cluster.local 后缀）。

Having a local cache will help improve the latency in such scenarios.
