下載 KubeKey
KubeKey 是新一代 Kubernetes 和 KubeSphere 安裝器，可幫助您以簡單、快速、靈活的方式安裝 Kubernetes 和 KubeSphere。

curl -sfL https://get-kk.kubesphere.io | VERSION=v1.0.1 sh -準備鏡像
如果您想讓安裝加快或者您的機房沒有外網，可以使用公司內部的私有倉庫，預先把鏡像推送到私有倉庫中，我這裏的倉庫使用harbor
下載離線安裝工具，我這裏只是用這個腳本來下載和推送鏡像
curl -L -O https://github.com/kubesphere/ks-installer/releases/download/v3.0.0/offline-installation-tool.sh
curl -L -O https://github.com/kubesphere/ks-installer/releases/download/v3.0.0/images-list.txt拉取鏡像
./offline-installation-tool.sh -s -l images-list.txt -d ./kubesphere-images
在./kubesphere-images目錄下能看到以下壓縮包

./offline-installation-tool.sh -l images-list.txt -d ./kubesphere-images -r hub.evbj.easou.com創建多節點集羣
您可用使用 KubeKey 同時安裝 Kubernetes 和 KubeSphere，通過自定義配置文件中的參數創建多節點集羣。
創建安裝有 KubeSphere 的 Kubernetes 集羣（例如 --with-kubesphere v3.0.0）
./kk create config --with-kubernetes v1.17.9 --with-kubesphere v3.0.0系統將創建默認的 config-sample.yaml 文件。您可以根據您的環境修改此文件。
