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' error execution phase wait-control-plane: couldn't initialize a Kubernetes cluster To see the stack trace of this error execute with --v=5 or higher

这是一个关于kubelet运行或健康状态问题的错误消息。根据错误消息，kubelet的健康检查失败，无法连接到`http://localhost:10248/healthz`。同时，还提到了可能导致此错误的一些原因和解决方法。

可能的原因包括kubelet没有运行或由于节点的某种错误配置而导致的不健康状态（例如禁用了所需的cgroups）。

如果你使用的是systemd-powered系统，你可以尝试使用以下命令来排查错误：
- `systemctl status kubelet`：查看kubelet的状态
- `journalctl -xeu kubelet`：查看kubelet的日志

另外，控制平面组件可能在容器运行时启动时崩溃或退出。你可以使用你常用的容器运行时CLI命令列出所有正在运行的Kubernetes容器来进行排查。

下面是一个在docker中列出所有运行的Kubernetes容器的示例命令：
- `docker ps -a | grep kube | grep -v pause`

一旦找到出错的容器，你可以使用以下命令查看其日志：
- `docker logs CONTAINERID`

最后，错误消息还提供了执行带有--v=5或更高级别参数的命令以查看错误堆栈跟踪的建议。

请注意，具体的解决方法可能需要更多上下文信息，并且根据你的环境和配置可能会有所不同。如果你需要更多帮助，请提供更详细的问题描述。

[kubelet-check] The HTTP call equal to 'curl -sSL http://localhost:10248/healthz'

该报错是由于kubelet无法连接到本地的10248端口导致的。解决方法是重启docker并重新初始化kubeadm。具体步骤如下：

# 添加以下内容
vim /etc/docker/daemon.json
{
  "exec-opts": ["native.cgroupdriver=systemd"]
}

# 重启docker
systemctl restart docker

# 重新初始化
kubeadm reset # 先重置
kubeadm init \

根据您提供的信息，kubeadm正在创建kube-scheduler的静态Pod清单，并在"/etc/kubernetes/manifests"目录下创建本地etcd的静态Pod清单。

然后，kubeadm等待kubelet以静态Pod的形式从"/etc/kubernetes/manifests"目录启动控制平面。这个过程可能需要最多4分钟。

但是，在等待过程中，出现了一些问题。警告信息"W0225 17:09:39.827262 43878 manifests.go:214] the default kube-apiserver authorization-mode is "Node,RBAC"; using "Node,RBAC""和"W0225 17:09:39.827977 43878 manifests.go:214] the default kube-apiserver authorization-mode is "Node,RBAC"; using "Node,RBAC""表示默认的kube-apiserver授权模式为"Node,RBAC"，并且将使用此模式。

警告信息"[kubelet-check] Initial timeout of 40s passed."和"[kubelet-check] It seems like the kubelet isn't running or healthy."表示在初始超时时间内无法连接到kubelet，可能是kubelet未运行或出现了健康问题。

警告信息"[kubelet-check] The HTTP call equal to 'curl -sSL http://localhost:10248/healthz' failed with error: Get http://localhost:10248/healthz: dial tcp 127.0.0.1:10248: connect: connection refused."表示尝试通过HTTP请求检查kubelet的健康状态失败，连接被拒绝。

这些警告表明kubelet可能在启动过程中遇到了问题。您可以检查kubelet的日志以获取更多详细信息，可能需要查看kubelet的日志文件以确定具体的问题所在。
