The connection to the server localhost:8080 was refused - did you specify the right host or port? 原因分析:kubectl无法与K8S集群通信; 解决方法:.kube目录是用于存放kubectl与K8S集群交互的缓存文件及相关配置文件; mkdir -p $HOME/.kubesudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/configsudo ...

控制节点通信,管理节点上的 Pod 和容器。kubelet 的主要职责包括:监控 pod 的状态并按需启动或停止容器、检查容器是否正常运行、与主控制节点通信,将节点状态和 Pod 状态上报给主控制节点、通过各种插件(如 volume 插件)与其他组件协同工作、管理容器的生命周期,包括启动、停止、重启等、拉取镜像。
虽然网上有大量从零搭建K8S的文章,但大都针对老版本,若直接照搬去安装最新的1.20版本会遇到一堆问题。故此将我的安装步骤记录下来,希望能为读者提供copy and paste式的集群搭建帮助。 我是在腾讯云CentOS的2台服务器上,在不访问国外网站的情况下使用kubeadm(最简单的部署工具)搭建K8S集群。其中,容器网络使用flannel,最...
