一、概述

KubeSphere 是 GitHub 上的一个开源项目,是成千上万名社区用户的聚集地。很多用户都在使用 KubeSphere 运行工作负载。对于在 Linux 上的安装,KubeSphere 既可以部署在云端,也可以部署在本地环境中,例如 AWS EC2、Azure VM 和裸机等。

KubeSphere 为用户提供轻量级安装程序 KubeKey(该程序支持安装 Kubernetes、KubeSphere 及相关插件),安装过程简单而友好。KubeKey 不仅能帮助用户在线创建集群,还能作为离线安装解决方案。

以下是可用的安装选项:

  • All-in-One:在单个节点上安装 KubeSphere(仅为让用户快速熟悉 KubeSphere)。
  • 多节点安装:在多个节点上安装 KubeSphere(用于测试或开发)。
  • 在 Linux 上离线安装:将 KubeSphere 的所有镜像打包(便于在 Linux 上进行离线安装)。
  • 高可用安装:安装具有多个节点的高可用 KubeSphere 集群,该集群用于生产环境。
  • 最小化安装:仅安装 KubeSphere 所需的最少系统组件。以下是最低资源要求:
    • 2 个 CPU
    • 4 GB 运行内存
    • 40 GB 存储空间
  • 全家桶安装:安装 KubeSphere 的所有可用系统组件,例如 DevOps、服务网格、告警等。

注意:并非所有选项都相互排斥,例如,您可以在离线环境中使用最小化安装将 KubeSphere 部署在多个节点上。

本文主要介绍在Linux系统下离线安装KubeSphere

 前提条件:

要开始进行多节点安装,您需要参考如下示例准备至少三台主机。

主机 IP主机名称角色系统版本
172.31.10.2node1联网主机用于制作离线包Ubuntu20.04 LTS
172.31.10.43node2离线环境主节点Ubuntu20.04 LTS
172.31.10.44node3离线环境镜像仓库节点Ubuntu20.04 LTS

部署准备

在私有云上创建3台云主机如下,物理机也可以

二、制作离线安装包

KubeKey 是一个用于部署 Kubernetes 集群的开源轻量级工具。它提供了一种灵活、快速、便捷的方式来仅安装 Kubernetes/K3s,或同时安装 Kubernetes/K3s 和 KubeSphere,以及其他云原生插件。除此之外,它也是扩展和升级集群的有效工具。

KubeKey v2.1.0 版本新增了清单(manifest)和制品(artifact)的概念,为用户离线部署 Kubernetes 集群提供了一种解决方案。manifest 是一个描述当前 Kubernetes 集群信息和定义 artifact 制品中需要包含哪些内容的文本文件。在过去,用户需要准备部署工具,镜像 tar 包和其他相关的二进制文件,每位用户需要部署的 Kubernetes 版本和需要部署的镜像都是不同的。现在使用 KubeKey,用户只需使用清单 manifest 文件来定义将要离线部署的集群环境需要的内容,再通过该 manifest 来导出制品 artifact 文件即可完成准备工作。离线部署时只需要 KubeKey 和 artifact 就可快速、简单的在环境中部署镜像仓库和 Kubernetes 集群。

2.1 登录node1执行以下命令下载并解压KubeKey

curl -sfL https://get-kk.kubesphere.io | VERSION=v3.0.13 sh - 

2.2 在node1上执行以下命令,并复制示例中的 manifest 内容。

vim manifest.yaml

注意: 

  • 若需要导出的 artifact 文件中包含操作系统依赖文件(如:conntarck、chrony 等),可在 operationSystem 元素中的 .repostiory.iso.url 中配置相应的 ISO 依赖文件下载地址或者提前下载 ISO 包到本地在 localPath 里填写本地存放路径并删除 url 配置项。

  • 开启 harbor 和 docker-compose 配置项,为后面通过 KubeKey 自建 harbor 仓库推送镜像使用。

  • 默认创建的 manifest 里面的镜像列表从 docker.io 获取。

  • 可根据实际情况修改 manifest-sample.yaml 文件的内容,用于之后导出期望的 artifact 文件。

  • 您可以访问 Release v3.0.7 🌈 · kubesphere/kubekey · GitHub 下载 ISO 文件。

 2.3 (可选)如果已经有k8s集群,可以在已有集群中执行 KubeKey 命令生成 manifest 文件,并参照步骤 2 中的示例修改 manifest 文件内容。

./kk create manifest 

2.4 导出制品 artifact

如果能够正常访问github,则使用以下命令导出

./kk artifact export -m manifest.yaml -o kubesphere.tar.gz 

如果不能够访问github,则使用以下命令导出 

export KKZONE=cn    ./kk artifact export -m manifest.yaml -o kubesphere.tar.gz 

注意:

制品(artifact)是一个根据指定的 manifest 文件内容导出的包含镜像 tar 包和相关二进制文件的 tgz 包。在 KubeKey 初始化镜像仓库、创建集群、添加节点和升级集群的命令中均可指定一个 artifact,KubeKey 将自动解包该 artifact 并在执行命令时直接使用解包出来的文件。

  • 导出时请确保网络连接正常。

  • KubeKey 会解析镜像列表中的镜像名,若镜像名中的镜像仓库需要鉴权信息,可在 manifest 文件中的 .registry.auths 字段中进行配置。

需要上传到其它离线节点的文件内容大致如下图:kubesphere.tar.gz(13G,里面包含了所需的镜像及组件)、kk、kubekey

三、开始离线安装

3.1 将下载的 KubeKey kubesphere.tar.gz(13G,里面包含了所需的镜像及组件)、kk通过 U 盘等介质拷贝至离线环境安装节点。

3.2 执行以下命令创建离线集群配置文件:

./kk create config --with-kubesphere v3.4.1 --with-kubernetes v1.23.15 -f config-sample.yaml 

 3.3 执行以下命令修改离线集群配置文件:

vim config-sample.yaml 

注意:

  • 按照实际离线环境配置修改节点信息。
  • 必须指定 registry 仓库部署节点(用于 KubeKey 部署自建 Harbor 仓库)。
  • registry 里必须指定 type 类型为 harbor,否则默认安装 docker registry。
apiVersion: kubekey.kubesphere.io/v1alpha2  kind: Cluster  metadata:    name: sample  spec:    hosts:    - {name: master, address: 192.168.0.3, internalAddress: 192.168.0.3, user: root, password: "<REPLACE_WITH_YOUR_ACTUAL_PASSWORD>"}    - {name: node1, address: 192.168.0.4, internalAddress: 192.168.0.4, user: root, password: "<REPLACE_WITH_YOUR_ACTUAL_PASSWORD>"}      roleGroups:      etcd:      - master      control-plane:      - master      worker:      - node1      # 如需使用 kk 自动部署镜像仓库,请设置该主机组 (建议仓库与集群分离部署,减少相互影响)      registry:      - node1    controlPlaneEndpoint:      ## Internal loadbalancer for apiservers      # internalLoadbalancer: haproxy        domain: lb.kubesphere.local      address: ""      port: 6443    kubernetes:      version: v1.23.15      clusterName: cluster.local    network:      plugin: calico      kubePodsCIDR: 10.233.64.0/18      kubeServiceCIDR: 10.233.0.0/18      ## multus support. https://github.com/k8snetworkplumbingwg/multus-cni      multusCNI:        enabled: false    registry:      # 如需使用 kk 部署 harbor, 可将该参数设置为 harbor,不设置该参数且需使用 kk 创建容器镜像仓库,将默认使用docker registry。      type: harbor      # 如使用 kk 部署的 harbor 或其他需要登录的仓库,可设置对应仓库的auths,如使用 kk 创建的 docker registry 仓库,则无需配置该参数。      # 注意:如使用 kk 部署 harbor,该参数请于 harbor 启动后设置。      #auths:      #  "dockerhub.kubekey.local":      #    username: admin      #    password: Harbor12345      # 设置集群部署时使用的私有仓库      privateRegistry: ""      namespaceOverride: ""      registryMirrors: []      insecureRegistries: []    addons: [] 

注意:以下图片为本次实验根据实际情况修改 ,特别注意节点名称、IP、用户名、密码要跟实际情况对应

 ​​​

3.4 执行以下命令安装镜像仓库:

./kk init registry -f config-sample.yaml -a kubesphere.tar.gz 

注意:

命令中的参数解释如下:

  • config-sample.yaml 指离线环境集群的配置文件。

  • kubesphere.tar.gz 指源集群打包出来的 tar 包镜像。

报错1跟2都是由于config-sample.yaml 文件填写内容有误导致:

 需要将config-sample.yaml文件中以下内容前面的注释去掉

另外可能需要将node2跟node3的/etc/hosts文件内容修改成以下图标显示

再次执行命令安装镜像库,显示安装成功,继续往下走

3.5 创建 Harbor 项目

注意:

由于 Harbor 项目存在访问控制(RBAC)的限制,即只有指定角色的用户才能执行某些操作。如果您未创建项目,则镜像不能被推送到 Harbor。Harbor 中有两种类型的项目:

  • 公共项目(Public):任何用户都可以从这个项目中拉取镜像。
  • 私有项目(Private):只有作为项目成员的用户可以拉取镜像。

Harbor 管理员账号:admin,密码:Harbor12345。Harbor 安装文件在 /opt/harbor , 如需运维 Harbor,可至该目录下。

方法 1:执行脚本创建 Harbor 项目。

a. 执行以下命令下载指定脚本初始化 Harbor 仓库:

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

 b. 执行以下命令修改脚本配置文件:

vim create_project_harbor.sh 
#!/usr/bin/env bash  # Copyright 2018 The KubeSphere Authors. # # Licensed under the Apache License, Version 2.0 (the "License"); # you may not use this file except in compliance with the License. # You may obtain a copy of the License at # #     http://www.apache.org/licenses/LICENSE-2.0 # # Unless required by applicable law or agreed to in writing, software # distributed under the License is distributed on an "AS IS" BASIS, # WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. # See the License for the specific language governing permissions and # limitations under the License.  url="http://192.168.6.2"   #这里替换成node3节点的IP 172.31.10.44,因为前面安装镜像库的时候在config-sample.yaml文件中定义了镜像库节点为node3 user="admin" passwd="Harbor12345"  harbor_projects=(library     kubesphere     calico     coredns     openebs     csiplugin     minio     mirrorgooglecontainers     osixia     prom     thanosio     jimmidyson     grafana     elastic     istio     jaegertracing     jenkins     weaveworks     openpitrix     joosthofman     nginxdemos     fluent     kubeedge )  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 ~ 

注意:

  • 修改 url 的值为url="http://192.168.6.2"   #这里替换成node3节点的IP 172.31.10.44,因为前面安装镜像库的时候在config-sample.yaml文件中定义了镜像库节点为node3 。

  • 需要指定仓库项目名称和镜像列表的项目名称保持一致。

  • 脚本末尾 curl 命令末尾加上 -k

c. 执行以下命令创建 Harbor 项目:

chmod +x create_project_harbor.sh 
./create_project_harbor.sh 

3.6 执行以下命令安装 KubeSphere 集群:

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

输入yes ,继续安装

参数解释如下:

  • config-sample.yaml:离线环境集群的配置文件。
  • kubesphere.tar.gz:源集群打包出来的 tar 包镜像。
  • --with-packages:若需要安装操作系统依赖,需指定该选项。

报错1:

如下图:node3节点172.31.10.43:443连接失败node3为镜像库节点

报错原因:

经过排查/etc/hosts文件发现,node2跟node3在hosts文件中ip都一样,发现前面在config-sample.yaml文件中将node3的ip地址写错了,导致安装失败,还是得细心啊,修改成正确的地址后,重新从3.2开始

报错2:

get manifest list failed by module cache
08:10:53 UTC failed: [LocalHost]
error: Pipeline[CreateClusterPipeline] execute failed: Module[CopyImagesToRegistryModule] exec failed:
failed: [LocalHost] [PushManifest] exec failed after 1 retries: get manifest list failed by module cache

报错原因,

在github上找到得

这个问题是因为官方的create_project_harbor.sh中,默认没有kubesphereio这个项目,而使用kubekey创建集群时,首先会CopyImagesToRegistry,如果没有kubeSphereio这个目录,会导致push不成功,会不执行CopyImagesToRegistry的Execute方法中的c.ModuleCache.Set("manifestList", manifestList)这段代码,最终在PushManifest的Execute时,会找不到manifestList。

解决办法就是在create_project_harbor.sh脚本中增加kubesphereio或者在harbor上手动创建kubesphereio或者config-sample.yaml中的namespaceOverride修改为”kubesphere”(不过这个我没试过)

kubekey在调用CopyImageOptions的Copy()时,虽然有重试机制,但最终并未把push不成功的error打印出来,导致后面的错误看起来非常不理解,希望能帮助到您!

在harbor上手动创建kubesphereio项目,创建完成以后重新执行上面的3.6安装 KubeSphere 集群的命令重新安装

在github上同样有人遇到一样的问题,需要在安装集群之前安装critcl

解决方法

安装critcl

选择指定版本下载:

https://github.com/kubernetes-sigs/cri-tools/releases

或在linux下直接下载

wget https://github.com/kubernetes-sigs/cri-tools/releases/download/v1.30.0/crictl-v1.30.0-linux-amd64.tar.gz

解压

sudo tar zxvf crictl-v1.30.0-linux-amd64.tar.gz -C /usr/local/bin

完成后检查版本

crictl --version

继续接着3.6的步骤,执行创建kubesphere集群的命令
