| 1 | +Jenkins |
| 2 | +=== |
| 3 | + |
| 4 | +下面图文示例，是通过 Docker 部署 Jenkins 并将 `Pipeline` 脚本运行在 `Docker` 中的教程，这样可以方便的使用任何版本的 `nodejs` 或者 `java` 的沙盒环境 |
| 5 | + |
| 6 | +## 部署 Jenkins |
| 7 | + |
| 8 | +获取 Jenkins 和 Jenkins agent 镜像，上传到服务器 |
| 9 | + |
| 10 | +```sh |
| 11 | +# 获取 Jenkins 镜像 |
| 12 | +docker pull --platform linux/amd64 jenkins/jenkins:2.468-jdk21 |
| 13 | +# 保存 Docker 镜像到本地文件 |
| 14 | +docker save -o jenkins-2.468-jdk21.tar jenkins/jenkins:2.468-jdk21 |
| 15 | +# 上传到服务器 |
| 16 | +scp -P 2222 jenkins-2.468-jdk21.tar [email protected]:/home/docker-images |
| 17 | + |
| 18 | +# 获取 Jenkins agent 镜像 |
| 19 | +docker pull --platform linux/amd64 jenkins/ssh-agent:jdk21 |
| 20 | +docker save -o jenkins-ssh-agent-jdk21.tar jenkins/ssh-agent:jdk21 |
| 21 | +scp -P 2222 jenkins-ssh-agent-jdk21.tar [email protected]:/home/docker-images |
| 22 | +``` |
| 23 | + |
| 24 | +创建一个 `Dockerfile`，基于 `jenkins/jenkins:2.468-jdk21` 镜像添加 Docker 支持： |
| 25 | + |
| 26 | +```Dockerfile |
| 27 | +FROM --platform=linux/amd64 jenkins/jenkins:2.468-jdk21 |
| 28 | + |
| 29 | +# 切换到 root 用户以安装 Docker CLI |
| 30 | +USER root |
| 31 | + |
| 32 | +# 安装必要的软件包 |
| 33 | +RUN apt-get update && apt-get install -y \ |
| 34 | + curl \ |
| 35 | + gnupg2 \ |
| 36 | + lsb-release \ |
| 37 | + software-properties-common |
| 38 | + |
| 39 | +# 安装 Docker CLI |
| 40 | +# RUN curl -fsSL https://get.docker.com | sh |
| 41 | +# 安装特定版本的 Docker CLI |
| 42 | +RUN curl -fsSL https://download.docker.com/linux/static/stable/x86_64/docker-26.1.4.tgz | tar xzvf - --strip-components=1 -C /usr/local/bin |
| 43 | + |
| 44 | +# 创建 docker 组并将 jenkins 用户添加到该组 |
| 45 | +RUN groupadd docker && usermod -aG docker jenkins |
| 46 | + |
| 47 | +# 切换回 jenkins 用户 |
| 48 | +USER jenkins |
| 49 | +``` |
| 50 | + |
| 51 | +构建 jenkins 新的镜像 |
| 52 | + |
| 53 | +```sh |
| 54 | +docker build --platform=linux/amd64 -t my-jenkins-docker-2468-jdk21 . |
| 55 | +# 保存 Docker 镜像为一个 tar 文件 |
| 56 | +docker save -o my-jenkins-docker-2468-jdk21.tar my-jenkins-docker-2468-jdk21 |
| 57 | +# 通过 SCP 传输 tar 文件到远程服务器 |
| 58 | +scp -P 2222 my-jenkins-docker-2468-jdk21.tar [email protected]:/home/docker-images |
| 59 | +``` |
| 60 | + |
| 61 | +```yml |
| 62 | +# https://github.com/jenkinsci/docker/blob/master/README.md#docker-compose-with-jenkins |
| 63 | +services: |
| 64 | + jenkins: |
| 65 | + image: my-jenkins-docker-2468-jdk21 # 自定义镜像 |
| 66 | + #image: jenkins/jenkins:2.468-jdk21 |
| 67 | + ports: |
| 68 | + - "8086:8080" |
| 69 | + volumes: |
| 70 | + - jenkins_home:/var/jenkins_home |
| 71 | + # 支持 docker |
| 72 | + - /var/run/docker.sock:/var/run/docker.sock |
| 73 | + ssh-agent: |
| 74 | + image: jenkins/ssh-agent:jdk21 |
| 75 | +volumes: |
| 76 | + jenkins_home: |
| 77 | +``` |
| 78 | +
|
| 79 | +确保您与 `docker-compose.yml` 在同一个目录中。并启动 `Jenkins`: |
| 80 | + |
| 81 | +```sh |
| 82 | +docker compose up -d # 启动 Jenkins |
| 83 | +docker compose down # 停止并删除与 Docker Compose 配置文件相关的所有容器、网络、卷和镜像 |
| 84 | +``` |
| 85 | + |
| 86 | +访问 jenkins: http://152.22.3.186:8086/ |
| 87 | + |
| 88 | +## 1. 安装插件 |
| 89 | + |
| 90 | +- [Git Parameter Plug-In](https://plugins.jenkins.io/git-parameter) 支持在 CI 上自动加载仓库分支 |
| 91 | + |
| 92 | +## 2. 添加凭证 |
| 93 | + |
| 94 | +<img src="./imgs/1.png" width="620" /> |
| 95 | + |
| 96 | +<img src="./imgs/2.png" width="620" /> |
| 97 | + |
| 98 | +<img src="./imgs/3.png" width="620" /> |
| 99 | + |
| 100 | +<img src="./imgs/4.png" width="620" /> |
| 101 | + |
| 102 | +## 3. 新建工作流 |
| 103 | + |
| 104 | +<img src="./imgs/5.png" width="620" /> |
| 105 | + |
| 106 | +修改配置 |
| 107 | + |
| 108 | +<img src="./imgs/6.png" width="620" /> |
| 109 | + |
| 110 | + |
| 111 | +设置 [`Git Parameter`](https://plugins.jenkins.io/git-parameter) 可以在构建的时候读取分支，选择分支 |
| 112 | + |
| 113 | +<img src="./imgs/7.png" width="620" /> |
| 114 | + |
| 115 | +<img src="./imgs/8.png" width="620" /> |
| 116 | + |
| 117 | +## 3. 添加构建选项，可以在构建前选择 `生产` 还是 `开发` 模式，在脚本中判断 |
| 118 | + |
| 119 | +<img src="./imgs/9.png" width="620" /> |
| 120 | + |
| 121 | +## 4. 选择 `Pipeline script from SCM` 指定脚本位置 |
| 122 | + |
| 123 | +<img src="./imgs/10.png" width="620" /> |
| 124 | + |
| 125 | +这方法是将 仓库 `config` 分支添加一个 `Jenkinsfile` 配置 |
| 126 | + |
| 127 | +## Nodejs |
| 128 | + |
| 129 | +安装 [Docker Pipeline](https://plugins.jenkins.io/git-parameter) 插件，支持从管道中构建和使用 `Docker` 容器。 |
| 130 | + |
| 131 | +```sh |
| 132 | +docker pull --platform linux/amd64 node:14.16.0 |
| 133 | +docker pull --platform linux/amd64 node:18 |
| 134 | +docker pull --platform linux/amd64 node:20 |
| 135 | +docker pull --platform linux/amd64 node:22 |
| 136 | +
|
| 137 | +# 保存 Docker 镜像到本地文件 |
| 138 | +docker save -o node14.16.tar node:14.16.0 |
| 139 | +# 上传到服务器 |
| 140 | +scp -P 2222 node14.16.tar [email protected]:/home/docker-images |
| 141 | +
|
| 142 | +docker save -o node18.tar node:18 |
| 143 | +scp -P 2222 node18.tar [email protected]:/home/docker-images |
| 144 | +
|
| 145 | +docker save -o node20.tar node:20 |
| 146 | +scp -P 2222 node20.tar [email protected]:/home/docker-images |
| 147 | +
|
| 148 | +docker save -o node22.tar node:22 |
| 149 | +scp -P 2222 node22.tar [email protected]:/home/docker-images |
| 150 | +``` |
| 151 | + |
| 152 | +Pipeline 脚本中使用 Docker nodejs 20 运行 |
| 153 | + |
| 154 | +```groovy |
| 155 | +pipeline { |
| 156 | + //agent any |
| 157 | + // pipeline 放到 docker 中执行 |
| 158 | + agent { |
| 159 | + docker { |
| 160 | + // 使用 Node.js 18 的 Docker 镜像 |
| 161 | + image 'node:20' |
| 162 | + // 可选：挂载 NPM 缓存目录，加速构建 |
| 163 | + args '-v /root/.npm:/root/.npm' |
| 164 | + } |
