概述 ---- 我们知道pod的ip不是固定的,是根据所在宿主机的docker0网卡生成的,每次重启,更新,调度等情况IP都会变,那pod与pod之间需要互相调用,肯定不能用ip的,因为地址不是固定的,...service现在分为以下类型 ClusterIP 集群内部容器访问地址,会生成一个虚拟IP 与pod不在一个网段。 NodePort 会在宿主机上映射一个端口,供外部应用访问模式。...比如一个nginx应用需要能被外部访问,就需要配置类型为type=NodePort,并且需要配置下nodePort: 30002(指定固定端口),这样的话外部使用http://ip:30002就可以访问这个应用了...spec.ports[*].nodePort 找到具体的值 如果我们指定一个端口,我们可以直接写在nodePort上,系统就会给你指派指定端口,但是这个值必须是指定范围内的。...基本上,NodePort 服务与普通的 “ClusterIP” 服务 YAML 定义有两点区别。 首先,type 是 “NodePort”。
