使用kubekey安装kubesphere

下载 KubeKey

KubeKey 是新一代 Kubernetes 和 KubeSphere 安装器，可帮助您以简单、快速、灵活的方式安装 Kubernetes 和 KubeSphere。

exportKKZONE=cn
curl-sfLhttps://get-kk.kubesphere.io|VERSION=v1.0.1sh-

准备镜像

如果您想让安装加快或者您的机房没有外网，可以使用公司内部的私有仓库，预先把镜像推送到私有仓库中，我这里的仓库使用harbor

下载离线安装工具，我这里只是用这个脚本来下载和推送镜像

curl-L-Ohttps://github.com/kubesphere/ks-installer/releases/download/v3.0.0/offline-installation-tool.sh
curl-L-Ohttps://github.com/kubesphere/ks-installer/releases/download/v3.0.0/images-list.txt

拉取镜像

./offline-installation-tool.sh-s-limages-list.txt-d./kubesphere-images
在./kubesphere-images目录下能看到以下压缩包
#ll

-rw-r--r--1rootroot448651153Feb215:23openpitrix-images.tar.gz

推送镜像到私有仓库，待脚本完成即可

./offline-installation-tool.sh-limages-list.txt-d./kubesphere-images-rhub.evbj.easou.com

创建多节点集群

您可用使用 KubeKey 同时安装 Kubernetes 和 KubeSphere，通过自定义配置文件中的参数创建多节点集群。

创建安装有 KubeSphere 的 Kubernetes 集群(例如 –with-kubesphere v3.0.0)

./kkcreateconfig--with-kubernetesv1.17.9--with-kubespherev3.0.0

系统将创建默认的 config-sample.yaml 文件。您可以根据您的环境修改此文件。
