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，我這里的倉庫使用harbor
下載離線安裝工具，我這里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
- # ll
- total 8606088
- -rw-r--r-- 1 root root 454465957 Feb 2 15:37 csi-images.tar.gz

- -rw-r--r-- 1 root root 445244294 Feb 2 14:50 istio-images.tar.gz
- -rw-r--r-- 1 root root 762326634 Feb 2 14:27 k8s-images.tar.gz
- -rw-r--r-- 1 root root 1297767607 Feb 2 14:40 ks-core-images.tar.gz
- -rw-r--r-- 1 root root 3439146357 Feb 2 15:19 ks-devops-images.tar.gz
- -rw-r--r-- 1 root root 733165078 Feb 2 14:46 ks-logging-images.tar.gz
- -rw-r--r-- 1 root root 448651153 Feb 2 15:23 openpitrix-images.tar.gz
推送鏡像到私有倉庫，待腳本完成即可
- ./offline-installation-tool.sh -l images-list.txt -d ./kubesphere-images -r hub.evbj.easou.com
創建多節點集群
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群。
創建安裝有 KubeSphere 的 Kubernetes 集群(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。
