Unfortunately, an error has occurred:

            timed out waiting for the condition



    This error is likely caused by:

            - The kubelet is not running

            - The kubelet is unhealthy due to a misconfiguration of the node in some way (required cgroups disabled)



    If you are on a systemd-powered system, you can try to troubleshoot the error with the following commands:

            - 'systemctl status kubelet'

            - 'journalctl -xeu kubelet'



    Additionally, a control plane component may have crashed or exited when started by the container runtime.

    To troubleshoot, list all containers using your preferred container runtimes CLI.



    Here is one example how you may list all Kubernetes containers running in docker:

            - 'docker ps -a | grep kube | grep -v pause'

            Once you have found the failing container, you can inspect its logs with:

            - 'docker logs CONTAINERID'

不幸的是，出现了一个错误:

等待条件超时

此错误可能由以下原因引起:

• kubelet没有运行

由于节点在某些方面配置错误，kubelet不健康(必需的cgroups被禁用)

如果你在一个系统驱动的系统上，你可以尝试用以下命令来排除错误:

• ‘systemctl status kubelet’

• ‘journalctl -xeu kubelet’

此外，在容器运行时启动时，控制面组件可能已经崩溃或退出。

要排除故障，请使用首选的容器运行时命令行列出所有容器。

这里有一个例子，你可以列出所有Kubernetes容器运行在docker:

• ‘docker ps -a | grep kube | grep -v pause’

一旦你找到了失败的容器，你可以用以下方法检查它的日志:

-“docker logs CONTAINERID”

您好，请问您是用哪种方法搭建的k8s？ minikube么，还是kubeadm？请检查kubelet的运行状态先

• 提问者 qq_罗_1 #1

  是用vagrant搭建k8s

• 麦兜搞IT 回复 提问者 qq_罗_1 #2

  是minikube么？
