添加节点

KubeCube 提供为已有集群添加节点的能力，同时也支持使用 kubeadm 的原生方式添加节点

⚠️ 注意通过 KubeCube 的脚本添加节点时，node 机器需要能够通过 ssh 访问 master 机器，支持公钥和密码两种 ssh 方式，执行脚本前可以在 node 上 ssh 到 master 测试连通性

v1.1.x

向集群添加工作节点

在新节点上执行部署脚本

  1. KUBECUBE_VERSION=v1.1
  1. export CUSTOMIZE="true";curl -fsSL https://kubecube.nos-eastchina1.126.net/kubecube-installer/${KUBECUBE_VERSION}/entry.sh | bash

tip: 你可以通过预先下载离线包和镜像来减少部署时间 export PRE_DOWNLOAD="true";curl -fsSL https://kubecube.nos-eastchina1.126.net/kubecube-installer/${KUBECUBE_VERSION}/entry.sh | bash

设置脚本参数，并按照提示继续运行安装脚本并等待新节点加入集群
