1、Cluster IP(虚拟IP):默认值,k8s系统给service自动分配的虚拟IP,只能在集群内部访问。想在外部访问需要结合node port。 2、Node Port(节点端口):将Service通过指定的Node上的端口暴露给外部,访问任意一个Node IP:nodePort都将路由到ClusterIP。 3、Load Balancer(负载均衡器):在 NodePort 的基础上,借助 cloud pr...

With node affinity, specific pods can enable to run on the desired node (Node selector also supports that feature, but node affinity is more flexible). If node is labelled with key-value, we can run some of the pods on that specific node. Terms for Node Affinity: requiredDuringScheduling...
