基于Docker的pipeline流水线
0. 整体架构
1. 准备工作
配置JenkinsMaster挂载Docker
docker run --name jenkins -itd \
-p 8081:8080 \
-p 50000:50000 \
-v ~/jenkins:/var/jenkins_home \
-v /var/run/docker.sock:/var/run/docker.sock \
-v /usr/local/bin/docker:/usr/bin/docker \
jenkins/jenkins:lts
解决权限问题/以root用户运行
docker exec -it -u root jenkins bash
usermod -aG root jenkins
id jenkins
uid=1000(jenkins) gid=1000(jenkins) groups=1000(jenkins),0(root),1(daemon)
2. 测试流水线
pipeline {
agent {
docker {
image 'maven:3.6.3-jdk-8'
args '-v $HOME/.m2:/root/.m2'
}
}
stages {
stage('Build') {
steps {
sh 'mvn -v'
}
}
}
}

3. 前后端未分离项目
对于代码库中既包含前端项目又包含后端项目的配置。可以启动多个容器。
pipeline {
agent none
stages {
stage('ServiceBuild') {
agent {
docker {
image 'maven:3.6.3-jdk-8'
args '-v $HOME/.m2:/root/.m2'
}
}
steps {
sh 'mvn -v && sleep 15'
}
}
stage('WebBuild') {
agent {
docker {
image 'node:7-alpine'
args '-v $HOME/.npm:/root/.npm'
}
}
steps {
sh 'node -v && sleep 15'
}
}
}
}
4. 前端项目流水线
初始化前端项目
ZeyangdeMacBook-Pro:demo zeyang$ vue-init webpack test
? Project name test
? Project description A Vue.js project
? Author adminuser <2560350642@qq.com>
? Vue build standalone
? Install vue-router? Yes
? Use ESLint to lint your code? No
? Set up unit tests No
? Setup e2e tests with Nightwatch? No
? Should we run `npm install` for you after the project has been created? (recom
mended) npm

5. FAQ
-
npm构建权限问题：使用root用户构建。设置容器运行用户 -u 0:0
-
npm打包慢问题：
2.1 挂载缓存卷 -v /var/jenkins_home/.npm:/root/.npm
2.2 设置淘宝源 npm config set registry https://registry.npm.taobao.org
