这里我对示例做一个简单的说明, 我希望pod 能够每10秒时间监控NodeJS的健康状态,我通过API:/checkLiveness 模拟获取这个健康情况,假设改变数据表的数据来模拟崩溃了即代表NodeJS有异常,Pod 需要捕捉这个情况并且重启。 API:/changeLivenessStatus 则是改变数据表的健康值。 #1、修改app/controller/home.js//改变容器...

Node(节点)是 kubernetes 集群中的计算机,可以是虚拟机或物理机。每个 Node(节点)都由 master 管理。一个 Node(节点)可以有多个Pod(容器组),kubernetes master 会根据每个 Node(节点)上可用资源的情况,自动调度 Pod(容器组)到最佳的 Node(节点)上。
四层负载均衡调度器Service可以以标签的形式选定一组带有指定标签的Pod,并监控和自动负载他们的Pod IP,通过NodePort暴露。当客户端访问kubernetes集群内部的应用时,数据包的走向如下面流程所示:client—>node ip:port—>service ip:port—>pod ip:port。 采用NodePort方式暴露服务面临的问题是,服务一旦多起来,NodePort在...
