联网主机用于制作离线包

实战环境涉及软件版本信息

  • 服务器芯片：Hygon C86 3350
  • 操作系统：麒麟 V10 SP3 x86_64
  • Docker: 24.0.9
  • Harbor: v2.10.1
  • KubeSphere：v3.4.1

  • KubeKey: v3.1.5

1. 本文介绍

本文还是以银河麒麟V10为例，在上一篇麒麟V10(X86)离线部署k8s和KubeSphere基础上进行简化和自动化sehll。其他操作系统同理。 后续将分享多操作系统离线包制作和一键部署教程，敬请关注。

1.1 确认操作系统配置

在执行下文的任务之前，先确认操作系统相关配置。

  • 操作系统类型

  • 操作系统内核
代码语言：javascript复制
[root@node1 kubesphere]# uname -a

2. 离线安装包制作

要制作离线包，需要一台同操作系统的在线环境，这里使用主机名：deploy 作为联网主机用于制作离线包。

2.1 下载麒麟系统k8s依赖包

此处为x86不同操作系统安装k8s的主要区别

代码语言：javascript复制
mkdir -p /root/kubesphere/k8s-init
该命令将下载
yum -y install openssl socat conntrack ipset ebtables chrony ipvsadm --downloadonly --downloaddir /root/kubesphere/k8s-init
编写安装脚本
vim install.sh
#!/bin/bash
rpm -ivh *.rpm --force --nodeps
打成压缩包，方便离线部署使用
tar -czvf k8s-init-KylinV10.tar.gz ./k8s-init/*

2.1 下载kk

  • 方式一
代码语言：javascript复制
[root@node1 kubesphere]# export KKZONE=cn
[root@node1 kubesphere]#  curl -sfL https://get-kk.kubesphere.io | VERSION=v3.1.5 sh -

Downloading kubekey v3.1.5 from https://kubernetes.pek3b.qingstor.com/kubekey/releases/download/v3.1.5/kubekey-v3.1.5-linux-amd64.tar.gz ...


Kubekey v3.1.5 Download Complete!
[root@node1 kubesphere]# ls
kk  kubekey-v3.1.5-linux-amd64.tar.gz
  • 方式二

使用本地电脑，直接去github下载 Releases · kubesphere/kubekey 上传至服务器/root/kubesphere目录解压

代码语言：javascript复制
tar zxf kubekey-v3.1.5-linux-amd64.tar.gz

2.3 编辑制品配置文件

在使用官方文档示例生成制品时出现了各种镜像错误，这里不再下载镜像(旧版本kk需要下载最少一个镜像)。镜像通过编写shell脚本处理。操作系统的iso也不再下载，使用第一步制作的依赖包。 此种方式优势

  • 制品体积更小(938M，不用harbor300多M，镜像文件额外1.9G)
  • 镜像变动更灵活
  • 组件按需增加/减少

劣势

  • 额外编写更多脚本
  • 额外增加离线部署过程
代码语言：javascript复制
vim manifest-kylin.yaml
代码语言：javascript复制
apiVersion: kubekey.kubesphere.io/v1alpha2
kind: Manifest
metadata:
  name: sample
spec:
  arches:
  - amd64
  operatingSystems:
  - arch: amd64
    type: linux
    id: kylin
    version: "V10"
    osImage: Kylin Linux Advanced Server V10
    repository:
      iso:
        localPath:
        url:
  kubernetesDistributions:
  - type: kubernetes
    version: v1.22.12
  components:
    helm:
      version: v3.14.3
    cni:
      version: v1.2.0
    etcd:
      version: v3.5.13
    containerRuntimes:
    - type: docker
      version: 24.0.9
    - type: containerd
      version: 1.7.13
    calicoctl:
      version: v3.27.3
    crictl:
      version: v1.29.0
    #docker-registry:
     # version: "2"
    harbor:
      version: v2.10.1
    docker-compose:
      version: v2.26.1

备注

  • 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，由于本文使用国产操作系统没有对应iso,而且最新kk支持不配置iso，这里不再配置。
  • **harbor、docker-compose和docker-registry **可二选一开启配置项，为后面通过 KubeKey 自建仓库推送镜像使用。

2.4 导出离线制品

代码语言：javascript复制
export KKZONE=cn
./kk artifact export -m manifest-kylin.yaml -o ks3.4-artifact.tar.gz

备注 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。

导出成功后，最后输出内容如下

代码语言：javascript复制
15:08:55 CST success: [LocalHost]
15:08:55 CST [ChownOutputModule] Chown output file
15:08:55 CST success: [LocalHost]
15:08:55 CST [ChownWorkerModule] Chown ./kubekey dir
15:08:55 CST success: [LocalHost]
15:08:55 CST Pipeline[ArtifactExportPipeline] execute successfully

2.5 手动拉取k8s相关镜像

编写推送脚本 load-push.sh

压缩k8s和ks镜像

代码语言：javascript复制
cd ..
tar -czvf ks3.4.1-images.tar.gz ks3.4.1-images

3. 离线安装集群

3.1 移除麒麟系统自带的podman

podman是麒麟系统自带的容器引擎，为避免后续与docker冲突，直接卸载。否则后续coredns/nodelocaldns也会受影响无法启动以及各种docker权限问题。所有节点执行

代码语言：javascript复制
yum remove podman

3.2 将安装包拷贝至离线环境

将下载的 KubeKey 、制品 artifact 、脚本和导出的镜像通过 U 盘等介质拷贝至离线环境安装节点。

3.3 安装k8s依赖包

所有节点执行,上传k8s-init-KylinV10.tar.gz解压后执行install.sh

3.4 修改config-sample.yaml配置文件

修改相关节点和harbor信息

  • 必须指定 registry 仓库部署节点（用于 KubeKey 部署自建 Harbor 仓库）。
  • registry 里指定 type 类型为 harbor，否则默认安装 docker registry。

3.5 使用制品安装harbor私有仓库

代码语言：javascript复制
./kk init registry -f config-sample.yaml -a ks3.4-artifact.tar.gz

harbor安装完成后，发现启动实现，排查问题后，需要给容器增加权限 privileged: true 以下4个harbor服务都需要添加权限 core/harbor-db/redis/registryctl/jobservice

验证

如果有服务启动失败，可重启harbor

代码语言：javascript复制
cd /opt/harbor
systemctl restart docker
docker-compose down
docker-compose up -d

创建harbor项目

代码语言：javascript复制
[root@node1 ks3.4.1-kylin]# cat create_project_harbor.sh
#!/usr/bin/env bash
   
url="https://dockerhub.kubekey.local"  #修改url的值为https://dockerhub.kubekey.local
user="admin"
passwd="Harbor12345"

harbor_projects=(
    kubesphereio
    kubesphere
    other
)

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}" -k #curl命令末尾加上 -k
done

3.6 推送ks相关镜像至harbor

解压2.7部分的镜像包，后执行

代码语言：javascript复制
./load-push.sh

3.7 创建集群

此处不再增加参数 -a ks3.4-artifact.tar.gz，因为在上一步创建harbor时，已经将artifact制品解压提取。此处再加-a参数，如果没有下载镜像或者iso有问题会报错。

代码语言：javascript复制
./kk create cluster -f config-sample.yaml

3.8 部署结果验证

介于篇幅长度，此处不再展示，结果可见上一篇，功能一切正常。

4. 遇到的问题

4.1 harbor问题

  • docker-compose.yaml问题

使用kk离线制品部署完了harbor2.10.1版本后，harbor会启动失败，需要给几个容器增加权限:privileged

  • 缺少helm-chart问题

Harbor 2.10.1已经移除helm-chart，如果项目使用了helm存放在harbor，可使用harbor2.5.3版本， 如果频繁需要用kk 制品部署，可修改kk源码中harbor版本

4.2 工作节点kubectl异常

现象：

代码语言：javascript复制
[root@node2 network-scripts]# kubectl get nodes
The connection to the server localhost:8080 was refused - did you specify the right host or port?
[root@node2 home]# kubectl config view
apiVersion: v1
clusters: null
contexts: null
current-context: ""
kind: Config
preferences: {}
users: null

解决： 要解决这个问题，需要将工作节点上的kubectl配置为指向Kubernetes master节点的API Server。通常，master节点会在/etc/kubernetes/admin.conf文件中保存集群的配置信息。可以将这个配置文件复制到工作节点上，并将其设置为kubectl使用的配置文件.

代码语言：javascript复制
scp /etc/kubernetes/admin.conf user@work-node:/root/.kube/config
代码语言：javascript复制
scp /etc/kubernetes/admin.conf root@192.168.120.190:/root/.kube/config

5. 总结

  • kk 3.1.5制作制品时不再需要必须包含最少一个镜像，因此我们可以只下载ks和k8s相关服务
  • kk 3.1.5 离线部署时不再需要必须包含系统需要的依赖iso，这样大大减少了我们国产系统适配的难度
  • kk 3.1.5离线部署时如果制品中未含镜像，使用-a 指定制品安装集群时会报错，此时我们可以使用./kk create cluster -f config-sample.yaml，不再加 -a指令创建集群
  • kk 3.1.5 部署的harbor有些许问题，需要我们手动修改。如果用不到harbor，制品时可不下载或者使用docker-registry，制品大小也可减少几百M

虽然kk 3.1.5 还有点问题，但是对比之前的版本已经优化了很大，尤其是不再检测系统和iso文件的匹配，对于国产化操作系统离线部署更加友好，推荐体验和使用。
