Minikube 無法啟動：“未找到節點‘minikube’”

Question

我有一個里面有 Minikube 的虛擬機。
當我使用minikube start --vm-driver=none命令運行它時效果很好。

我的主機崩潰了，因此虛擬機也崩潰了。 我重新啟動了主機，然后重新啟動了虛擬機，當我嘗試運行 minikube 時，它​​失敗並顯示大量信息：

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

當我運行minikube status我收到：

host: Running
kubelet: Running
apiserver: Stopped
kubectl: Correctly Configured: pointing to minikube-vm at 10.240.0.23  

API服務器似乎有問題。 kubelet 服務器正在運行，但出現以下錯誤：

kubelet.go:2266] node "minikube" not found

我運行minikube logs並看到相同的錯誤：

://localhost:8443/api/v1/nodes?fieldSelector=metadata.name%3Dminikube&limit=500&resourceVersion=0: dial tcp 127.0.0.1:8443: connect: connection refused

似乎連接到 127.0.0.1:8443 有問題，因此發送未找到“minikube”的錯誤。

我看到這里已經提到了這個問題，但我嘗試了解決方案，但對我不起作用。
我停止了 minikube 並刪除了它並重新開始，但出現了同樣的問題。

知道這是什么原因嗎？

Answer 1

我是這樣解決的：

minikube stop && minikube delete
docker rm -f $(docker ps -aq)
reboot

重啟后就正常啟動了。
但是我仍然不明白如何在不重新啟動的情況下修復它。
重新啟動是丟失的部分。 如果您在不重啟的情況下執行這些命令並嘗試再次啟動它，它將無法啟動。

Answer 2

大多數情況下，當我們在 swarm 模式下運行 docker 時會出現此錯誤

此問題的一個簡單解決方案可能是運行以下命令：

$ docker leave swarm
$ docker network prune
