如何搭建自己的CI/CD平台:Gitlab+Jenkins+Docker+Harbor+K8s集群搭建CICD平台(持续集成部署Hexo博客Demo)

如果你讨厌一个人，你实际讨厌的是你自己的某些部分。我们自身没有的东西，是不会干扰到我们的。仁者见仁，智者见智。——德尔曼 黑塞《德米安》

写在前面

  • 聊聊CICD的环境搭建以及一个基于Hexo的博客系统在CICD流程中的配置Demo
  • 很早就想着写这样一篇博文,但是没有时间,之前写了一半,正好春节假期把剩下的一般写完.
  • 本文属于Devpos实战类文章，基本没有理论，所有，小伙伴需要对devops有些基本的了解，
  • 博文中讲的CICD属于Devops的一部分
  • 当然小伙伴们也可以找一些云服务商提供的商业的Depops平台去学习，一般有免费的体验，比如华为云的软开云平台。
  • 博文涉及内容:
    • Gitlab+Jenkins+Docker+Harbor+K8S集群 的CICD搭建教程
    • 在搭建好的CICD平台上持续集成部署hexo博客系统，Demo有些简陋，仅用于学习。
  • 其中Gitlab+Jenkins +Harbor都是通过容器化部署
  • 篇幅有限，关于CD环境k8s集群这里用之前部署好的，并且已经做了kubeconfig证书,关于这方便感兴趣小伙伴可以看看我之前的文章
  • 下面为涉及到的机器：
用到的机器 ip 域名
客户机 192.168.26.1 本地物理机:
Gitlab+Jenkins+Docker 192.168.26.55 虚机：liruilongs.github.io
docker镜像仓库:harbor 192.168.26.56 虚机：vms56.liruilongs.github.io
k8s集群-master节点 192.168.26.81 虚机：vms81.liruilongs.github.io
k8s集群-node节点 192.168.26.82 虚机：vms82.liruilongs.github.io
k8s集群-node节点 192.168.26.83 虚机：vms83.liruilongs.github.io
拓扑图
这里客户机用本地的IDE持续编码，然后push代码到gitlab，gitlab中的web钩子触发jenkins中配置好的构建触发器，通过shell命令拉取gitlab仓库中的代码，然后通过拉取的应用源码和Dockerfile文件来构建应用镜像，构建完成后将应用镜像push到harbor私有镜像仓库，然后通过shell命令的方式在jenkins中用kubelet客户端将镜像从私有仓库拉取到k8s集群并更新其deploy中的镜像,默认deploy更新副本的方式为滚动更新，整个流程中，只有客户机push代码是手手动的方式，其他全是自动

上帝借由各种途径使人变得孤独，好让我们可以走向自己。 ——赫尔曼·黑塞《德米安》

一、CICD服务器环境搭建

CI即为持续集成(Continue Integration,简称CI)，用通俗的话讲，就是持续的整合版本库代码编译后制作应用镜像。建立有效的持续集成环境可以减少开发过程中一些不必要的问题、提高代码质量、快速迭代等,

常用的工具和平台有:

Jenkins :基于Java开发的一种持续集成工具,用于监控持续重复的工作,旨在提供一个开放易用的软件平台,使软件的持续集成变成可能。
Bamboo: 是一个企业级商用软件,可以部署在大规模生产环境中。

CD即持续交付Continuous Delivery和持续部署Continuous Deployment，用通俗的话说，即可以持续的部署到生产环境给客户使用，这里分为两个阶段，持续交付我理解为满足上线条件的过程，但是没有上线，持续部署，即为上线应用的过程

关于CD环境，我们使用以前搭建好的K8s集群，K8s集群可以实现应用的健康检测，动态扩容，滚动更新等优点，关于K8s集群的搭建，小伙伴可以看看我的其他文章

我们来搭建CI服务器:操作服务器： liruilongs.github.io：192.168.26.55

2.安装配置远程镜像仓库harbor

下面我们要配置私有的docker镜像仓库，用到的机器为：

操作服务器:vms56.liruilongs.github.io:192.168.26.56

这里仓库我们选择harbor，因为有web页面，当然也可以使用 registry

harbor的配置

harbor的安装使用步骤
安装并启动docker并安装docker-compose
上传harbor的离线包
导入harbor的镜像
编辑harbor.yml
修改hostname 为自己的主机名,不用证书需要注释掉https
harbor_admin_password 登录密码
安装compose
运行脚本 ./install.sh
在浏览器里输入IP访问
docker login IP –家目录下会有一个.docker文件夹

下面我们开始安装

首先需要设置selinux、防火墙
