红帽全球峰会10.2. 连接健康检查实现
在集群中，连接检查控制器或编配连接验证检查。连接测试的结果存储在 openshift-network-diagnostics 命名空间中的 PodNetworkConnectivity 对象中。连接测试会每分钟以并行方式执行。
Cluster Network Operator（CNO）将几个资源部署到集群，以发送和接收连接性健康检查：
- 健康检查源
-
此程序部署在一个由
Deployment对象管理的单个 pod 副本集中。程序会消耗PodNetworkConnectivity对象，并连接到每个对象中指定的spec.targetEndpoint。 - 健康检查目标
- pod 作为集群中每个节点上的守护进程集的一部分部署。pod 侦听入站健康检查。在每个节点上存在这个 pod 可以测试到每个节点的连接。
