Jenkins流水线支持多组件按照依赖顺序部署-华为云

云应用引擎 CAE-操作步骤:脚本说明

脚本说明每个组件都需要在pipeline中的envionment获取组件参数，用于判断参数化构建时是否选中，执行下面脚本： _{component_name}="${sh(script:' echo $Model_Name| grep -w -o "{component_name}" || echo "error" ', returnStdout: true).trim()}" 表1 参数说明参数名称描述 Model_Name 配置构建参数中的Name。 {component_name} 配置构建参数中的Choose Source for Value中的value里面填写的组件名称之一。每个组件都需要配置一个stage，用于组件的升级任务，如果是串行执行的，则按照先后顺序放置stage的位置，如果是并行执行的任务就放置在stage('Build parallel jobs')中的parallel中。 stage脚本： stage('Build {component_name}') { when { environment name: '_{component_name}', value: '{component_name}' } steps { sh ''' echo "start to build {component_name}" ''' script{ def componentBuild=build(job: '{component_jenkins_task}') //打印执行任务的结果 println componentBuild.getResult() } } } 表2 参数说明参数描述 {component_name} 配置构建参数中的Choose Source for Value中的value里面填写的组件名称之一。 {component_jenkins_task} jenkins中创建的用于组件升级的任务名称，例如：用于componentA组件升级的任务名称如图6所示。图6 组件升级任务名称

云应用引擎 CAE-操作步骤:流水线脚本

流水线脚本流水线脚本支持componentA、componentB、componentC和componentD，4个组件中的一个或多个同时升级，并且按照依赖顺序先升级componentA，再并行升级componentB和componentC，最后升级componentD。如果构建时没有勾选到的组件会跳过，不执行升级。 pipeline { agent any environment{ //构建时选择的组件以‘,’隔开的格式存在变量Model_Name里 //判断变量Model_Name里的可选组件是否存在，如果存在，把组件名赋值给对应变量，如果不存在，把字符串"error"赋值给对应变量。 //用于判断后续组件是否需要构建 _componentA="${sh(script:' echo $Model_Name| grep -w -o "componentA" || echo "error" ', returnStdout: true).trim()}" _componentB="${sh(script:' echo $Model_Name| grep -w -o "componentB" || echo "error" ', returnStdout: true).trim()}" _componentC="${sh(script:' echo $Model_Name| grep -w -o "componentC" || echo "error" ', returnStdout: true).trim()}" _componentD="${sh(script:' echo $Model_Name| grep -w -o "componentD" || echo "error" ', returnStdout: true).trim()}" } stages { stage('Build componentA') { //when条件判断当环境变量"_componentA" = "componentA"时，表示构建时选择了该组件，执行此stage，否则跳过此stage when { environment name: '_componentA', value: 'componentA' } steps { sh ''' echo "start to build componentA" ''' script{ //build(job: 'componentA') 表示执行componentA任务，这个任务是jenkins中创建的任务名称，用于componentA组件升级的任务 def componentBuild=build(job: 'componentA') //打印执行任务的结果 println componentBuild.getResult() } } } stage('Build parallel jobs') { //failFast true 表示parallel并行的stage中只要有一个失败，其他并行任务也会中止 //不加failFast true，parallel中失败的stage不会影响其他并行的stage执行，直到所有的并行任务执行完成 //failFast true //按需添加 //parallel 表示里面的stage是并行执行的，只要其中有一个stage执行失败，则"Build parallel jobs"这个stage是失败的，它后续的stage不会执行 parallel { stage('Build componentB') { when { environment name: '_componentB', value: 'componentB' } steps { sh ''' echo "start to build componentB" ''' script{ def componentBuild=build(job: 'componentB') println componentBuild.getResult() } } } stage('Build componentC') { when { environment name: '_componentC', value: 'componentC' } steps { sh ''' echo "start to build componentC" ''' script{ def componentBuild=build(job: 'componentC') println componentBuild.getResult() } } } } } stage('Build componentD') { when { environment name: '_componentD', value: 'componentD' } steps { sh ''' echo "start to build componentD" ''' script{ def componentBuild=build(job: 'componentD') println componentBuild.getResult() } } } } }

云应用引擎 CAE-操作步骤:使用流水线升级多个组件

使用流水线升级多个组件选择流水线，单击“参数化构建”。图7 参数化构建选择要升级的组件，可以选择一个或多个同时升级，本示例选择全部组件同时升级，单击“开始构建”。图8 选择组件可在构建历史中查看流水线任务执行结果。图9 查看执行结果流水线日志如下所示，可以看出先升级componentA，再并行升级componentB和componentC，最后升级componentD。 Started by user admin Running in Durability level: MAX_SURVIVABILITY [Pipeline] Start of Pipeline [Pipeline] node Running on Jenkins in /root/.jenkins/workspace/pipeline-arrange [Pipeline] { [Pipeline] sh + echo componentA,componentB,componentC,componentD + grep -w -o componentA [Pipeline] sh + echo componentA,componentB,componentC,componentD + grep -w -o componentD [Pipeline] sh + echo componentA,componentB,componentC,componentD + grep -w -o componentB [Pipeline] sh + echo componentA,componentB,componentC,componentD + grep -w -o componentC [Pipeline] withEnv [Pipeline] { [Pipeline] stage [Pipeline] { (Build componentA) [Pipeline] sh + echo 'start to build componentA' start to build componentA [Pipeline] script [Pipeline] { [Pipeline] build Scheduling project: componentA Starting building: componentA #13 [Pipeline] echo SUC CES S [Pipeline] } [Pipeline] // script [Pipeline] } [Pipeline] // stage [Pipeline] stage [Pipeline] { (Build parallel jobs) [Pipeline] parallel [Pipeline] { (Branch: Build componentB) [Pipeline] { (Branch: Build componentC) [Pipeline] stage [Pipeline] { (Build componentB) [Pipeline] stage [Pipeline] { (Build componentC) [Pipeline] sh [Pipeline] sh + echo 'start to build componentB' start to build componentB [Pipeline] script + echo 'start to build componentC' start to build componentC [Pipeline] { [Pipeline] script [Pipeline] { [Pipeline] build Scheduling project: componentB [Pipeline] build Scheduling project: componentC Starting building: componentB #12 Starting building: componentC #12 [Pipeline] echo SUCCESS [Pipeline] } [Pipeline] // script [Pipeline] } [Pipeline] // stage [Pipeline] } [Pipeline] echo SUCCESS [Pipeline] } [Pipeline] // script [Pipeline] } [Pipeline] // stage [Pipeline] } [Pipeline] // parallel [Pipeline] } [Pipeline] // stage [Pipeline] stage [Pipeline] { (Build componentD) [Pipeline] sh + echo 'start to build componentD' start to build componentD [Pipeline] script [Pipeline] { [Pipeline] build Scheduling project: componentD Starting building: componentD #10 [Pipeline] echo SUCCESS [Pipeline] } [Pipeline] // script [Pipeline] } [Pipeline] // stage [Pipeline] } [Pipeline] // withEnv [Pipeline] } [Pipeline] // node [Pipeline] End of Pipeline Finished: SUCCESS 登录CAE控制台查看组件状态，“最近一次变更状态/时间”列显示状态为“升级成功”，表示组件升级成功。图10 查看组件

云应用引擎 CAE-概述:解决方案

解决方案新建一条jenkins流水线来编排多个组件，自动按照依赖顺序构建升级，并使用参数化构建的方式，同时支持单个或多个组件的升级。下面以一个示例说明流水线执行流程。有4个组件分别是componentA、componentB、componentC和componentD，其中componentD依赖componentB和componentC，componentB和componentC依赖componentA。流水线执行流程：
