KubeSphere 3.3.0 離線安裝教程

作者：老Z，中電信數智科技有限公司山東分公司運維架構師，云原生愛好者，目前專注于云原生運維，云原生領域技術堆疊涉及Kubernetes、KubeSphere、DevOps、OpenStack、Ansible等，

KubeKey 是一個用于部署 K8s 集群的開源輕量級工具，

它提供了一種靈活、快速、便捷的方式來僅安裝 Kubernetes/K3s，或同時安裝 K8s/K3s 和 KubeSphere，以及其他云原生插件，除此之外，它也是擴展和升級集群的有效工具，

KubeKey v2.1.0 版本新增了清單 (manifest) 和制品 (artifact) 的概念，為用戶離線部署 K8s 集群提供了一種解決方案，

manifest 是一個描述當前 K8s 集群資訊和定義 artifact 制品中需要包含哪些內容的文本檔案，

在過去，用戶需要準備部署工具，鏡像 tar 包和其他相關的二進制檔案，每位用戶需要部署的 K8s 版本和需要部署的鏡像都是不同的，現在使用 KubeKey，用戶只需使用清單 manifest 檔案來定義將要離線部署的集群環境需要的內容，再通過該 manifest 來匯出制品 artifact 檔案即可完成準備作業，離線部署時只需要 KubeKey 和 artifact 就可快速、簡單的在環境中部署鏡像倉庫和 K8s 集群，

KubeKey 生成 manifest 檔案有兩種方式，

• 利用現有運行中的集群作為源生成 manifest 檔案，也是官方推薦的一種方式，具體參考 KubeSphere 官網的離線部署檔案，
• 根據 模板檔案 手動撰寫 manifest 檔案，

第一種方式的好處是可以構建 1:1 的運行環境，但是需要提前部署一個集群，不夠靈活度，并不是所有人都具備這種條件的，

因此，本文參考官方的離線檔案，采用手寫 manifest 檔案的方式，實作離線環境的安裝部署，

本文知識點

• 定級：入門級
• 了解清單 (manifest) 和制品 (artifact) 的概念
• 掌握 manifest 清單的撰寫方法
• 根據 manifest 清單制作 artifact
• 離線部署 KubeSphere 和 Kubernetes

演示服務器配置

演示環境涉及軟體版本資訊

• 作業系統：CentOS-7.9-x86_64

• KubeSphere：3.3.0

• Kubernetes：1.24.1

• Kubekey：v2.2.1

• Ansible：2.8.20

• Harbor：2.5.1

離線部署資源制作

下載 KubeKey

# 在zdevops-master 運維開發服務器執行

# 選擇中文區下載(訪問github受限時使用)
$ export KKZONE=cn

# 下載KubeKey
$ mkdir /data/kubekey
$ cd /data/kubekey/
$ curl -sfL https://get-kk.kubesphere.io | VERSION=v2.2.1 sh -

獲取 manifest 模板

參考 https://github.com/kubesphere/kubekey/blob/master/docs/manifest-example.md

有兩個參考用例，一個簡單版，一個完整版，參考簡單版就可以，

獲取 ks-installer images-list

$ wget https://github.com/kubesphere/ks-installer/releases/download/v3.3.0/images-list.txt

文中的 image 串列選用的 Docker Hub 倉庫其他組件存放的公共倉庫，國內建議統一更改前綴為 registry.cn-beijing.aliyuncs.com/kubesphereio

修改后的完整的鏡像串列在下面的 manifest 檔案中展示，

請注意，example-images 包含的 image 中只保留了 busybox，其他的在本文中沒有使用，

獲取作業系統依賴包

$ wget https://github.com/kubesphere/kubekey/releases/download/v2.2.1/centos7-rpms-amd64.iso

將該 ISO 檔案放到制作離線鏡像的服務器的 /data/kubekey 目錄下

生成 manifest 檔案

根據上面的檔案及相關資訊，生成最終 manifest.yaml，

命名為 ks-v3.3.0-manifest.yaml

manifest 修改說明

• 開啟 harbor 和 docker-compose 配置項，為后面通過 KubeKey 自建 harbor 倉庫推送鏡像使用，
• 默認創建的 manifest 里面的鏡像串列從 docker.io 獲取，替換前綴為 registry.cn-beijing.aliyuncs.com/kubesphereio，
• 若需要匯出的 artifact 檔案中包含作業系統依賴檔案（如：conntarck、chrony 等），可在 operationSystem 元素中的 .repostiory.iso.url 中配置相應的 ISO 依賴檔案下載地址為 localPath ，填寫提前下載好的 ISO 包在本地的存放路徑，并將 url 配置項置空，
• 您可以訪問 https://github.com/kubesphere/kubekey/releases/tag/v2.2.1 下載 ISO 檔案，

匯出制品 artifact

$ export KKZONE=cn

$ ./kk artifact export -m ks-v3.3.0-manifest.yaml -o kubesphere-v3.3.0-artifact.tar.gz

制品 (artifact) 說明

• 制品（artifact）是一個根據指定的 manifest 檔案內容匯出的包含鏡像 tar 包和相關二進制檔案的 tgz 包，
• 在 KubeKey 初始化鏡像倉庫、創建集群、添加節點和升級集群的命令中均可指定一個 artifact，KubeKey 將自動解包該 artifact 并在執行命令時直接使用解包出來的檔案，

匯出 Kubekey

$ tar zcvf kubekey-v2.2.1.tar.gz kk kubekey-v2.2.1-linux-amd64.tar.gz

離線安裝集群

傳輸離線部署資源到部署節點

將以下離線部署資源，傳到部署節點 (通常是第一個 master 節點) 的 /data/kubekey 目錄，

• Kubekey：kubekey-v2.2.1.tar.gz
• 制品 artifact：kubesphere-v3.3.0-artifact.tar.gz

執行以下操作，解壓 kubekey，

$ cd /data/kubekey
$ tar xvf kubekey-v2.2.1.tar.gz

創建離線集群組態檔

• 創建組態檔

$ ./kk create config --with-kubesphere v3.3.0 --with-kubernetes v1.24.1 -f config-sample.yaml

• 修改組態檔

$ vim config-sample.yaml

修改內容說明

• 按照實際離線環境配置修改節點資訊，
• 按實際情況添加 registry 的相關資訊，

在 Harbor 中創建專案

本文采用提前部署好的 Harbor 來存放鏡像，部署程序參考我之前寫的 基于 KubeSphere 玩轉 k8s-Harbor 安裝手記，

你可以使用 kk 工具自動部署 Harbor，具體參考官方離線部署檔案，

• 下載創建專案腳本模板

$ curl -O https://raw.githubusercontent.com/kubesphere/ks-installer/master/scripts/create_project_harbor.sh

• 根據實際情況修改專案腳本

#!/usr/bin/env bash

# Harbor 倉庫地址
url="https://registry.zdevops.com.cn"

# 訪問 Harbor 倉庫用戶
user="admin"

# 訪問 Harbor 倉庫用戶密碼
passwd="Harbor12345"

# 需要創建的專案名串列，正常只需要創建一個**kubesphereio**即可，這里為了保留變數可擴展性多寫了兩個，
harbor_projects=(library
    kubesphereio
    kubesphere
)

for project in "${harbor_projects[@]}"; do
    echo "creating $project"
    curl -u "${user}:${passwd}" -X POST -H "Content-Type: application/json" "${url}/api/v2.0/projects" -d "{ \"project_name\": \"${project}\", \"public\": true}"
done

• 執行腳本創建專案

$ sh create_project_harbor.sh

推送離線鏡像到 Harbor 倉庫

將提前準備好的離線鏡像推送到 Harbor 倉庫，這一步為可選項，因為創建集群的時候也會再次推送鏡像，為了部署一次成功率，建議先推送，

$ ./kk artifact image push -f config-sample.yaml -a  kubesphere-v3.3.0-artifact.tar.gz

創建集群并安裝 OS 依賴

$ ./kk create cluster -f config-sample.yaml -a kubesphere-v3.3.0-artifact.tar.gz --with-packages

引數說明

• config-sample.yaml：離線環境集群的組態檔，
• kubesphere-v3.3.0-artifact.tar.gz：制品包的 tar 包鏡像，
• --with-packages：若需要安裝作業系統依賴，需指定該選項，

查看集群狀態

$ kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l 'app in (ks-install, ks-installer)' -o jsonpath='{.items[0].metadata.name}') -f

正確安裝完成后，您會看到以下內容：

總結

感謝您完整的閱讀完本文，為此，您應該 Get 到了以下技能

• 了解了清單 (manifest) 和制品 (artifact) 的概念
• 了解 manifest 和 image 資源的獲取地址
• 手寫 manifest 清單
• 根據 manifest 清單制作 artifact
• 離線部署 KubeSphere 和 Kubernetes
• Harbor 鏡像倉庫自動創建專案
• Ansible 使用的小技巧

目前為止，我們已經完成了最小化環境的 KubeSphere 和 K8s 集群的部署，但是，這僅僅是一個開始，后續還有很多配置和使用技巧，敬請期待 ...
