Jenkins定制化容器​

由于每次新部署Jenkins环境，均需要安装很多必要的插件，因此考虑把插件提前做到镜像中

Dockerfile

FROM jenkins/jenkins:2.375.1-lts-jdk11
LABEL maintainer="inspur_lyx@hotmail.com"

ENV JENKINS_UC https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates
ENV JENKINS_UC_DOWNLOAD https://mirrors.tuna.tsinghua.edu.cn/jenkins
ENV JENKINS_OPTS="-Dhudson.model.UpdateCenter.updateCenterUrl=https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json"
ENV JENKINS_OPTS="-Djenkins.install.runSetupWizard=false"

## 用最新的插件列表文件替换默认插件文件
COPY plugins.txt /usr/share/jenkins/ref/

## 执行插件安装
RUN jenkins-plugin-cli -f /usr/share/jenkins/ref/plugins.txt

plugins.txt

ace-editor:1.1
allure-jenkins-plugin:2.28.1
ant:1.10
antisamy-markup-formatter:1.6
apache-httpcomponents-client-4-api:4.5.10-1.0
authentication-tokens:1.3
...

get_plugin.sh

> admin:admin!@jenkins.luffy.com需要替换成Jenkins的用户名、密码及访问地址

#!/usr/bin/env bash
curl -sSL  "http://admin:admin!@jenkins.luffy.com/pluginManager/api/xml?depth=1&xpath=/*/*/shortName|/*/*/version&wrapper=plugins" | perl -pe 's/.*?<shortName>([\w-]+).*?<version>([^\<]+)()(\\<\/\w+\\>)+/\1:\2\n/g'|sed 's/ /:/' \> plugins.txt
## 执行构建，定制jenkins容器

至此，我们可以使用定制化的镜像启动jenkins服务

本章小结​

自由风格项目弊端：

  • 任务的完成需要在Jenkins端维护大量的配置
  • 没法做版本控制
  • 可读性、可移植性很差，不够优雅
