Kubernetes初始化失败dial tcp 127.0.0.1:10248: connect: connection refused.

在进行kubernetes初始化的时报错

[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.
[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 127.0.0.1:10248: connect: connection refused.

解决办法

docker驱动与Kubelet的驱动程序不同导致

1、查看docker驱动

docker info | grep Driver			# Cgroup Driver: systemd

2、查看kubelet驱动

systemctl show --property=Environment kubelet |cat

[root@master ~]# systemctl show --property=Environment kubelet |cat
Environment=KUBELET_KUBECONFIG_ARGS=–bootstrap-kubeconfig=/etc/kubernetes/bootstrap-kubelet.conf --kubeconfig=/etc/kubernetes/kubelet.conf KUBELET_CONFIG_ARGS=–config=/var/lib/kubelet/config.yaml

3、修改docker驱动

查看/etc/docker/daemon.json文件，没有的话手动创建，添加以下内容

[root@master ~]# cat /etc/docker/daemon.json 
{
    
    
  "registry-mirrors": ["https://registry.cn-hangzhou.aliyuncs.com"],
  "exec-opts": ["native.cgroupdriver=cgroupfs"],
  "log-driver": "json-file",
  "log-opts": {
    
    
    "max-size": "100m"
  },
  "storage-driver": "overlay2",
  "storage-opts": [
    "overlay2.override_kernel_check=true"
  ]
}

4、重启docker

systemctl daemon-reload && systemctl restart docker

至此重新初始化即可！
