kubernets初始化失败提示节点找不到

Question

kubernets初始化一直失败 我真的是人都傻了
安装k8s之前做的配置

install(){
  hostname
  yuminstall
  shut
  kernel
  ipvs
  dockerinstall
  container
}

install


read -p "是否要重启(yes or no)" cluser
if [[ $cluser == yes ]]; then
  reboot
elif [[ $cluser == no ]]; then
  echo "已退出"
fi

重启之后，安装
yum install -y kubelet kubeadm kubectl
设置开机自启
systemctl enable kubelet.service
开始初始化
kubeadm init \

--apiserver-advertise-address=192.168.1.10
--image-repository registry.aliyuncs.com/google_containers
--kubernetes-version 1.24.2
--service-cidr=10.96.0.0/12
--pod-network-cidr=10.244.0.0/16

然后就 一直失败
这个是journald的日志

这个是message的日志

就一直提示节点找不到
中间还有一个容器进行时containerd的报错 到最后也没看到哪里出问题了

Answer 1

master上的apiserver启动正常么
