downloading amd64 kubeadm v1.28.8 ...修改配置文件 采用 3 个节点同时作为 control-plane、etcd 和 worker 节点。
编辑配置文件 k8s-v1288.yaml主要修改 kind: Cluster 小节的相关配置
修改 kind: Cluster 小节中 hosts 和 roleGroups 等信息修改说明如下。
hosts指定节点的 IP、ssh 用户、ssh 密码、ssh 端口roleGroups指定 3 个 etcd、control-plane 节点复用相同的机器作为 3 个 worker 节点internalLoadbalancer启用内置的 HAProxy 负载均衡器domain可自定义域名clusterName可使用默认值 cluster.localautoRenewCerts该参数可以实现证书到期自动续期默认为 truecontainerManager使用 containerd
部署完成需要大约 10-20 分钟左右会在终端上看到类似于下面的输出。
