部署高可用 Kubernetes

KubeCube 部署脚本提供部署高可用 k8s 的能力,当然,你也可以使用其他工具搭建高可用的 k8s 集群

开始安装

在 master1 上执行部署脚本

KUBECUBE_VERSION=v1.4
export CUSTOMIZE="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 Kubernetes 安装完成,master2 和 master3 加入 control-plane 的方式与之相同

  • CONTROL_PLANE_ENDPOINT 为高可用 k8s-apiserver 的 vip,在此我们用任意 master 节点的 ip 代替

# if install k8s

# k8s cni, support now is calico only

# there are four node mode below:
