jenkins maven传统构建改造jenkins pipeline方式

前言：

此刻朋友们对“multiselectcss”都比较讲究，兄弟们都想要知道一些“multiselectcss”的相关知识。那么小编同时在网上搜集了一些关于“multiselectcss””的相关知识，希望小伙伴们能喜欢，姐妹们一起来了解一下吧！

jenkins 在公司内部用了好几年了，之前一直基于jenkins 插件功能实现代码下载、编码打包、单元测试、自动化测试、安全渗透测试、部署发布上线。通过jenkins 集成实现devops 功能。

现有的jenkins 发布流程图如下：

我们通过第三方工具+jenkins 整合初步实现了devops一套开发测试运维一体化。以下是我们使用开源或者第三方软件实现devops 工具链。

我们在查看一下jenkins 现有具体配置

以上设置主要是jenkins参数设置功能，可以通过参数化勾选选择性执行单元测试、静态代码扫描、自动化测试、自动化渗透测试、是否发布程序等功能

通过勾选选择性执行动作，最后项目构建点击“开始构建”按钮执行

下面源码配置，我们用的是SVN做代码库管理，配置信息如下

设置构建触发器，在这块设置定时触发，这样我们可以在周末定时实现全量构建。

配置制品JAR 仓库管理

编译打包构建配置

上面截图看不清楚，这里把编译打包命令行代码如下

clean package -U -Dmaven.test.skip=true -Dproject.build.finalName=$BUILD_NAME -Dnacos.server=$cloud_nacos org.jacoco:jacoco-maven-plugin:prepare-agent -Dmaven.test.failure.ignore=true -P$mode --settings $mavenSettings dependency:analyze-report

下面我们通过shell命令行执行相关命令执行

具体命令行代码如下

#如果是周末，则执行单元测试和依赖检查等，忽略构建时选的参数weekDay=$(date +%w)#weekDay=6#if [[ $weekDay -eq 6 || $weekDay -eq 0 ]];then#echo "今天是周六或者周末"#单元测试#unitTest=true#sonar扫描#sonarScan=true#依赖检查#dependencyCheck=true#不进行部署#deploy=false#进行安全扫描#securityScan=true#fi#maven settings.xml目录#mavenSettings="/usr/local/apache-maven-3.5.3-yf2b/conf/settings.xml "#maven打包#mvn clean package -Dmaven.test.skip=true  -Dproject.build.finalName=$BUILD_NAME  -Dnacos.server=$cloud_nacos org.jacoco:jacoco-maven-plugin:prepare-agent -Dmaven.test.failure.ignore=true -P$mode --settings $mavenSettings   dependency:analyze-report if [ $unitTest = 'true' ];thenecho "------------------------执行单元测试------------------------"Dmvn test --settings $mavenSettings fiif [ $sonarScan = 'true' ];thenecho "------------------------执行sonar扫描------------------------"mvn org.jacoco:jacoco-maven-plugin:prepare-agent org.jacoco:jacoco-maven-plugin:report  -Dmaven.test.failure.ignore=true  sonar:sonar -Dsonar.host.url= -Dsonar.login=8063215ecb67d87d6c249f84b76ec87f44fae997 -Dsonar.sources=./src -Dsonar.tests=. -Dsonar.test.inclusions=**/*test*/** -Dsonar.exclusions=**/*test*/** -Dsonar.java.source=1.8 -Dsonar.exclusions=src/main/java/com/base/web/common/adapter/DruidSlf4jLoggerFilterEx.java,**/domain/**,**/vo/**,/*DO.java,src/main/java/com/base/web/openapi/xxxx/**,src/main/java/com/base/web/openapi/base/**,src/main/java/com/base/web/system/**,/*Utils.java,/*Util.java,src/main/java/com/base/web/common/utils/**,src/main/java/com/base/web/common/base/**,src/main/java/com/base/web/xxxx/utils/**,src/main/java/com/base/web/openapi/utils/**,**/*.js,**/*.html,**/*.css -Dsonar.test.exclusions=**/*.js,**/*.html,**/*.css  -Dsonar.language=java  -Dsonar.java.binaries=target/classes  -Dsonar.projectVersion=1.0 -Dsonar.projectName=xxx_dev_java_docker_xxx -Dsonar.sourceEncoding=UTF-8 -Dsonar.projectKey=xxx_dev_java_docker_xxx  -Dsonar.dependencyCheck.summarize=true  -Dsonar.projectBaseDir=/opt/jenkins/workspace/xxx_dev_java_docker_xxx  -Dsonar.java.coveragePlugin=jacoco  -Dsonar.core.codeCoveragePlugin=jacoco -Dsonar.jacoco.reportPath=target/jacoco.exec -Dsonar.coverage.jacoco.xmlReportPaths=target/site/jacoco/jacoco.xmlfi  #if [ $dependencyCheck = 'true' ];then#echo "------------------------执行依赖检查------------------------"#/usr/local/dependency-check/bin/dependency-check.sh --disableRetireJS -s `pwd`/ -f XML -o `pwd`/dependency-check-report.xml#fi#if [ $deploy = 'false' ];then#echo "------------------------不进行部署，部署脚本结束------------------------"#exit 0#fiif [ $deploy = 'true' ];thenecho "------------------------执行部署脚本------------------------"#===========以下是通用配置============#项目名projectName=xxxx-dev-java-docker-xxxx#镜像名称#IMAGE_NAME=192.168.xx.202/xx/sjzxpt/jcpt/v1.0.0/dev:v1.0.0_${BUILD_TIMESTAMP}.${BUILD_NUMBER}IMAGE_NAME=yf.registry.xxx.com/xxx/sjzxpt/jcpt/v1.0.0/dev:v1.0.0_${BUILD_TIMESTAMP}.${BUILD_NUMBER}#IMAGE_NAME=192.168.xxx.202/xxx/sjzxpt/jcpt/v1.0.0/dev:v1.0.0_20210308.47#192.168.xx.202/xxxx/sjzxpt/jcpt/v1.0.0/dev:v1.0.0_${BUILD_TIMESTAMP}.${BUILD_NUMBER}#删除之前的镜像#sudo docker rmi -f $IMAGE_NAMEecho '================生成镜像================'sudo docker build -t $IMAGE_NAME ./echo '================推送镜像================'sudo docker login --username=xxx--password=xxxx  yf.registry.xxxxx.com #登录私有库sudo docker push $IMAGE_NAMEecho '================结束推送镜像================'#新加k8s镜像地址K8S_IMAGE_NAME=yf.p2p.registry.xxxx.com:65001/xxx/sjzxpt/xxx/v1.0.0/dev:v1.0.0_${BUILD_TIMESTAMP}.${BUILD_NUMBER}echo -------------------------------------# 创建k8s容器cat >k8s-$projectName-rc.yaml <<EFOapiVersion: apps/v1  kind: StatefulSet  metadata:    name: $projectName  namespace: xxxx  labels:      app: $projectName  spec:    replicas: 2  revisionHistoryLimit: 10  serviceName: $projectName  selector:      matchLabels:        app: $projectName  template:      metadata:        labels:          app: $projectName     spec:      containers:          -

以上代码行简单解释一下，其中大致可以分为 4大块。

1. 编译打包阶段（通过代码行控制是否单元测试、是否静态代码扫描、是否第三方安全JAR 检查、是否部署发布控制。

2. docker 镜像编译打包上传habor 私有化镜像仓库

3. K8S 创建app pod

4. K8S 创建网络服务

5. 容器发布K8S 后执行自动化安全渗透扫描

下面我们通过jenkins 集成了metersphere 自动化测试

我们又编写了接口自动化后发报告，把报告生产后自动通知企业微信里面

最后构建成功后在发企业微信通知项目构建成功的消息通知

jenkins 构建后日志记录

我们通过以上构建方式发现一个问题，jenkins配置非常繁琐，很多配置功能需要依赖jenkins插件。而且编写的shell 脚本太长了，一旦shell脚本修改或者jenkins 服务器宕机，之前配置全部丢失。（研发环境资源有限，不太可能考虑jenkins 双机备份等工作）

我们能不能简化jenkins 配合，将复杂的配置简化掉，减少shell 容易修改的问题呢？答案是肯定的。可以利用jenkisn pipeline 改造发布流程。可以让大家先看一下效果。

通过上面是不是很直观的知道某个环节花费了多少时间，哪个环节执行失败还是成功。界面是不是美观多了呢。呵呵，我们在看jenkins 里面的配置。

构建头换成

参数化的地方没有太大变化，这里面不做介绍。项目打包变成流水线配置

后面呢，后面都没了。那么东西都弄哪里了呢？都弄到jenkinsfile 中了

相当于jenkinsfile 文件放到SVN 通过代码库管理起来（这样可以规避SHELL脚本丢失的问题）

利用流水线执行SVN 代码库里面jenkinsfile 脚本来实现以上繁琐的步骤。

下面重点介绍一下jenkinsfile 里面有哪些东西

以上是jenkinsfile 文件定义部分，在后面项目个构建中通过参数换传值替换使用。

下面我们介绍 parameters参数，这里面主要是结合jenkins 勾选功能使用

jenkins 界面选择效果图

通过以上方式，我们再增加jenkins流程就在上面代码中添加相应parameters 定义，后面我们在jenkinsfile 文件中增加具体实现就行了，不需要考虑各种jenkins 插件功能了。

下面具体介绍stages 步骤，我们拿初始化参数为案例来说

这个对应上面parameters定义部分步骤具体实现。

后面的拉取代码、Maven设置、获取需要部署的模块、编译构建、单元测试、sonar扫描、自动化渗透扫描、打包docker生成镜像、部署到K8S平台、上次制品到JAR仓库中，这里面就不细细展开说明了。

细心的小伙伴可以研究一下jenkinsfile 来具体分析。这类我们只提供实现的思路，具体可以根据实际项目来修改。Jenkinsfile 文件具体内容如下：

下面介绍流水线脚本结构

以上配置文件 dockfiel k8s 脚本和本身流水线无关，每个公司管理要求不一样。这里面我就不细介绍了。感兴趣的小伙伴可以留言，后面如果有需求我会再介绍这方面的知识、欢迎关注、留言、点赞。

jenkins 流水线如何配置呢，下面简单介绍一下

选择 jenkins新建“流水线”工程

配置jenkinsfile文件的svn地址

如果项目是微服务架构，可以设置多模块，具体构建勾选一个或者多个模块也可。

改造后jenkins 整体界面少很多了。而且构建的灵活性大大增加。

总之，jenkins是一个持续构建发布的平台，利用它我们大大简化平时部署实时和发布工作，让研发把精力放在写代码上面，提高研发效率。
