2.2.6 部署k8s的Node节点 master安装后,控制台有如下命令:复制该命令到各个node节点去执行,把node节点加入到master集群里 根据提示,在192.168.18.101和192.168.18.102上添加如下的命令: # 把当前node节点加入到集群里;注意,下边的命令粘贴的是上边master安装后,控制台打印出来的命令 kubeadm join 192.168.18.100:6443 -...
Kubelet:Master派到Node节点代表,管理本机容器 Kube-Proxy:提供网络代理、负载均衡等操作 ① Master Node K8S集群控制节点,对集群进行调度管理,接受集群外用户去集群操作请求;Master Node 由 API Server、Scheduler、ClusterState Strore(ETCD数据库)和 Controller ManagerServer所组成。

disruptions when a single node or zone fails. By default, soft anti-affinity settings based on nodes are configured for CoreDNS. Some or all CoreDNS pods may be deployed on the same node due to insufficient nodes. In this case, we recommend that you delete the CoreDNS pods and reschedule ...
