我期待着回答答案。请联系我。非常感谢。

运行以下命令应该可以使它工作，因为kubelet可能会卡在崩溃循环中：
sudo systemctl stop kubelet
sudo rm -rf /var/lib/kubelet/pods/*
sudo systemctl start kubelet
答案 1 :(得分：1)
您提供的日志是不够的。 您可以使用
查看所有详细登录tail -n 1000 /var/log/messages
在我的情况下，我首先停止kube-apiserver服务，然后启动它，并在/var/log/messages中搜索。得到我的错误是一个文件被删除，因为我重新启动机器。它可能不会是你的理由，但你可以发现它使用我说的命令。
祝你好运。答案 2 :(得分：1)
我有一个非常类似的问题，在我的情况下，我修复了将KUBE_API_PORT=更改为我的系统上可用的另一个KUBE_API_PORT=9090
尝试curl 127.0.0.1:8080以确定该端口是否被其他服务使用
