这篇具有很好参考价值的文章主要介绍了如果遇见k8s初始化报错：It seems like the kubelet isn‘t running or healthy.。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

报错命令如下：

[kubelet-check] It seems like the kubelet isn't running or healthy.
[kubelet-check] The HTTP call equal to 'curl -sSL http://localhost:10248/healthz' failed with error: Get "http://localhost:10248/healthz": dial tcp [::1]:10248: connect: connection refused.

其解决方法：

进入docker配置文件：

vi /etc/docker/daemon.json

添加：

 "exec-opts": ["native.cgroupdriver=systemd"]

#这里需要注意的这里是字典，然后需要在配置前面一句加上逗号

it seems like the kubelet isn't running or healthy. [kubelet-check] the http,kubernetes,容器,云原生

最后重启docker和

systemctl restart kubelet

systemctl restart docker

然后重新初始化：

我这里重新初始化再一次报错

报错主要代码:

Initial timeout of 40s passed.

报错全部内容 :

[wait-control-plane] Waiting for the kubelet to boot up the control plane as static Pods from directory "/etc/kubernetes/manifests". This can take up to 4m0s
[kubelet-check] Initial timeout of 40s passed.

    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

我一看应该是初始化阿里源有个地方不对，通过摸索：

运行：

kubeadm init \
  --apiserver-advertise-address=192.168.42.131 \
 --control-plane-endpoint=cluster-endpoint \
  --image-repository registry.aliyuncs.com/google_containers \
  --kubernetes-version v1.23.0 \
  --service-cidr=10.96.0.0/12 \
  --pod-network-cidr=10.244.0.0/16 \
  --ignore-preflight-errors=all

最后成功：文章来源地址https://www.toymoban.com/news/detail-770375.html

Your Kubernetes control-plane has initialized successfully!

To start using your cluster, you need to run the following as a regular user:

  mkdir -p $HOME/.kube
  sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
  sudo chown $(id -u):$(id -g) $HOME/.kube/config

Alternatively, if you are the root user, you can run:

  export KUBECONFIG=/etc/kubernetes/admin.conf

You should now deploy a pod network to the cluster.
Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:
  https://kubernetes.io/docs/concepts/cluster-administration/addons/

You can now join any number of control-plane nodes by copying certificate authorities
and service account keys on each node and then running the following as root:

  kubeadm join 192.168.42.131:6443 --token 845e5p.dl37n3jsojq5roko \
	--discovery-token-ca-cert-hash sha256:aece2d35673e8e0ed80ddf943d70af1a219376189af76ab680fddd3295cb4083 \
	--control-plane 

Then you can join any number of worker nodes by running the following on each as root:

kubeadm join 192.168.42.131:6443 --token 845e5p.dl37n3jsojq5roko \
	--discovery-token-ca-cert-hash sha256:aece2d35673e8e0ed80ddf943d70af1a219376189af76ab680fddd3295cb4083
