jenkins中如何集成commander应用的完整步骤
前言
Jenkins 是一款流行的开源持续集成(Continuous Integration)工具,广泛用于项目开发,具有自动化构建、测试和部署等功能。
最近参加公司的集成测试平台的开发,在开发中遇到了不少问题,两个星期的迭代也即将完成,在这也用这篇博客记录下开发中的问题,供读者参考
公司的应用较多,所以需要了解这几种应用在jenkins中如何做构建,我自己参与的有两种commander的应用,一种是大数据类的,一个是我们服务端架构组的scala应用
1、大数据应用BigData
配置如下:
配置文件对应的xml文件:通过crul获取xml配置文件:http://host/job/tar_py_dwx_dev/config.xml
<project> <actions/> <description/> <keepDependencies>false</keepDependencies> <properties> <com.dabsquared.gitlabjenkins.connection.GitLabConnectionProperty plugin="gitlab-plugin@1.5.5"> <gitLabConnection/> </com.dabsquared.gitlabjenkins.connection.GitLabConnectionProperty> <hudson.plugins.promoted__builds.JobPropertyImpl plugin="promoted-builds@3.1"> <activeProcessNames> <string>Deploy DEV</string> </activeProcessNames> </hudson.plugins.promoted__builds.JobPropertyImpl> </properties> <scm class="hudson.plugins.git.GitSCM" plugin="git@3.8.0"> <configVersion>2</configVersion> <userRemoteConfigs> <hudson.plugins.git.UserRemoteConfig> <url>ssh://git@172.0.10.182:10022/bigdata/dwx.git</url> <credentialsId>84f4be19-ea8d-4271-8cfb-42af8f507285</credentialsId> </hudson.plugins.git.UserRemoteConfig> </userRemoteConfigs> <branches> <hudson.plugins.git.BranchSpec> <name>*/develop</name> </hudson.plugins.git.BranchSpec> </branches> <doGenerateSubmoduleConfigurations>false</doGenerateSubmoduleConfigurations> <submoduleCfg class="list"/> <extensions/> </scm> <assignedNode>!macmini</assignedNode> <canRoam>false</canRoam> <disabled>false</disabled> <blockBuildWhenDownstreamBuilding>false</blockBuildWhenDownstreamBuilding> <blockBuildWhenUpstreamBuilding>false</blockBuildWhenUpstreamBuilding> <triggers> <hudson.triggers.SCMTrigger> <spec>H/5 * * * *</spec> <ignorePostCommitHooks>false</ignorePostCommitHooks> </hudson.triggers.SCMTrigger> </triggers> <concurrentBuild>false</concurrentBuild> <builders> <hudson.tasks.Shell> <command> project=dwx1 cd ${WORKSPACE} tar zcvf ${project}.tar.gz * aws s3 cp ${project}.tar.gz s3://lattebank-jenkins-build-dev/${JOB_BASE_NAME}/${BUILD_NUMBER}/ --region cn-north-1 rm -rf ${project}.tar.gz </command> </hudson.tasks.Shell> </builders> <publishers/> <buildWrappers/> </project>
从xml中获取的信息有点和图中的配置文件有点对应不上
对于promotion的脚本在xml配置文件中是无法获取的,这时候就有一个问题,这种api是无法获取到promotion的的脚本,同时这也给我们的工作带来了极大的挑战,那也意味着单纯的通过这种方法是无法实现commander应用的部署,和通过平台的方式去直接操作jenkins的配置
但经过查询相关的api并不能找到相关的内容,经过不懈的努力,终于找到了和promote build 插件相关的api
查询:http://host/job/jobName/promotion/process/promotionName/config.xml
这个接口能获取到它的xml文件,但是并不能对该配置文件进行增加和修改
对此我自己封装了一些方法:
/** * @author chenlang * date 2018/5/7 */ @Slf4j public class JenkinsPromotionUtils { private static final String SUB_PATH_PROMOTION_COOMMAND = "/hudson.plugins.promoted__builds.PromotionProcess"; private static final String SUB_PATH_BUILD = "/buildSteps"; private static final String SUB_PATH_BUILDER_SHELL_COMMAND = "/hudson.tasks.Shell/command"; private static final String PATH_PROMOTION_COMMAND = SUB_PATH_PROMOTION_COOMMAND + SUB_PATH_BUILD + SUB_PATH_BUILDER_SHELL_COMMAND; private static String CREATE_PROMOTION_JSON = "{'properties':{'stapler-class-bag':'true','hudson-plugins-promoted_builds-JobPropertyImpl':{'promotions':{'activeItems':{'name':'%s','isVisible':'','icon':'star-gold','hasAssignedLabel':false,'assignedLabelString':'','conditions':{'stapler-class-bag':'true'}}}}}}"; private static final String CONTENT_TYPE = "application/x-www-form-urlencoded"; public static void updatePromotionShell(Document jobConfigDocument, String jobName, JenkinsPromotionClient jenkinsPromotionClient, String promotionShell, String path) throws IOException, DocumentException { if (StringUtils.isBlank(promotionShell)) { return; } String promotionName = getPromotionName(jobConfigDocument, path); Document document = jenkinsPromotionClient.getJobPromotionXml(jobName, promotionName); document.selectSingleNode(PATH_PROMOTION_COMMAND).setText(promotionShell); jenkinsPromotionClient.updateJob(jobName, promotionName, document.asXML()); } public static void createPromotionShell(Document jobConfigDocument, String tmpJobName, String jobName, String promotionShell, String path, JenkinsPromotionClient jenkinsPromotionClient) throws IOException, DocumentException { if (StringUtils.isBlank(promotionShell)) { return; } String promotionName = getPromotionName(jobConfigDocument, path); Document document = jenkinsPromotionClient.getJobPromotionXml(tmpJobName, promotionName); document.selectSingleNode(PATH_PROMOTION_COMMAND).setText(promotionShell); Map<String, String> map = Maps.newHashMap(); map.put("Content-Type", CONTENT_TYPE); map.put("json", String.format(CREATE_PROMOTION_JSON, promotionName)); try { jenkinsPromotionClient.createJob(jobName, map); } catch (Exception e) { log.error("初创promotion时失败" + e); } jenkinsPromotionClient.createJob(jobName, promotionName, document.asXML()); } public static String getPromotionName(Document jobConfigDocument, String path) { return jobConfigDocument.selectSingleNode(path).getText(); } }

其中的方法封装了对promote build插件中关于配置的增删改查,以及promotion脚本的构建
