Minikube 启动失败："node 'minikube' not found"
Minikube failed to start: "node 'minikube' not found"
我有一个虚拟机，里面有 Minikube。
当我使用 minikube start --vm-driver=none 命令 运行 它时，它工作得很好。
我的主机崩溃了，因此虚拟机也崩溃了。我重新启动了主机，然后是虚拟机，当我尝试 运行 minikube 时，它失败了，并显示了很多信息：

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, e.g. docker.
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'

minikube failed :( exiting with error code 1
当我 运行 minikube status 我收到：
host: Running
kubelet: Running
apiserver: Stopped
kubectl: Correctly Configured: pointing to minikube-vm at 10.240.0.23
API服务器似乎有问题。 kubelet 服务器是 运行ning 但有这样的错误：
kubelet.go:2266] node "minikube" not found
我 运行 minikube logs 和我看到相同的错误：

似乎连接到 127.0.0.1:8443 时出现问题，因此发送 "minikube" 未找到的错误。
我看到这个问题已经被提及 here 但我尝试了解决方案，但它对我不起作用。
我停止了 minikube 并将其删除并重新启动它，但出现了同样的问题。
知道这是什么原因吗？
我是这样解决的：
minikube stop && minikube delete
docker rm -f $(docker ps -aq)
reboot
重启后正常启动。
但是我还是不明白不重启怎么解决。
重新启动是缺失的部分。如果您在不重启的情况下执行这些命令并尝试再次启动它，它将不会启动。
大多数情况下，当我们 运行 docker 在 swarm 模式下
时会出现此错误
此问题的一个简单解决方案是运行以下命令：
$ docker leave swarm
$ docker network prune
