11.3. 配置 pod 连接检查放置
作为集群管理员，您可以通过修改名为 cluster 的 network.config.openshift.io 对象来配置运行连接 pod 的节点。
先决条件
-
安装 OpenShift CLI (
oc) 。
流程
要编辑连接检查配置，请输入以下命令：
$ oc edit network.config.openshift.io cluster
-
在文本编辑器中，更新
networkDiagnostics小节，以指定您要用于源和目标 pod 的节点选择器。 - 要提交您的更改，请保存更改并退出文本编辑器。
验证
要验证源和目标 pod 是否在预期节点上运行，请输入以下命令：
$ oc get pods -n openshift-network-diagnostics -o wide
