添加计算集群

KubeCube 可以添加其它集群作为计算集群,前提是,计算集群能够访问管控集群的 k8s api-server 和 KubeCube,默认情况下 KubeCube 使用 NodePort 对外暴露服务,用户可自行使用 ingress 进行暴露

v1.4.x

方式一:部署新集群并添加

在 linux 机器上,需要构建 Kubernetes 集群并安装 KubeCube 依赖项

开始安装

  1. KUBECUBE_VERSION=v1.4
  1. export CUSTOMIZE="true";curl -fsSL https://kubecube.nos-eastchina1.126.net/kubecube-installer/${KUBECUBE_VERSION}/entry.sh | bash

设置安装脚本参数

该安装模式下,需要修改以下参数:

INSTALL_KUBECUBE_PIVOT=“false”

INSTALL_KUBECUBE_MEMBER=“true”

INSTALL_KUBERNETES=“true”

MEMBER_CLUSTER_NAME=“member-1”

MASTER_IP=”${node ip}”

KUBECUBE_HOST=”${pivot node ip}”

MEMBER_CLUSTER_NAME 表示计算集群的名字,注意,不能与已有的计算集群名称同名, ${node ip} 表示你运行脚本所在 node 机器的 ip,该 node 需要可操作 kubectl, ${pivot node ip} 表示管控集群 node 机器的 ip,用于向 KubeCube 注册集群

方式二:纳管已有集群

添加已有集群需要从 console 页面获取添加集群的定制脚本

在 console 页面中获取添加集群的脚本

add-member-cluster

使用脚本添加集群

在集群的 node 机器上,使用从 console 中下载的脚本,该机器需要能够执行 kubectl

  1. /bin/bash add_cluster.sh

等待集群添加完成

add-cluster

在 console 中确认新集群

check-cluster
