我写了一个简单的node.js应用程序，它在端口上侦听并返回HTML。我可以docker运行node.js应用程序，并在适当的端口转发后，愉快地使用它。
+ docker run -p 7081:7081 split-server
现在我想在kubernetes中运行该应用程序。我在一台mac上，设置了minikube和虚拟盒子我还为我的本地应用程序设置了一个本地docker注册表，使用此处的说明。
无论我尝试什么组合，它都不起作用。悬而未决的描述如下。我想我已经接近了，但我就是无法从kubectl获得有用的调试输出：
+ kubectl describe pod split-server

我应该在哪里狩猎？我缺少什么工具kubectl日志每次都是空的。。。如果应用程序运行正常，应该有一行日志记录。
由于某种原因(手动或有问题(，minikube节点被标记为unschedulable，您可以尝试删除污点：
kubectl taint nodes --all node.kubernetes.io/unschedulable-
或者在你的吊舱上添加一个容忍度：
apiVersion: v1
kind: Pod
metadata:
name: ...
...
spec:
containers:
- name: ...
...
tolerations:
- key: "node.kubernetes.io/unschedulable"
operator: "Exists"
effect: "NoSchedule"
对挂起的pod进行故障排除的方法是查看描述pod时得到的事件。在您的案例中，主节点被标记为不可调度，因此您正面临此问题。
要修复的命令就像侯赛因所说的一样。请参阅本页，了解如何对未决吊舱进行故障排除：
