操作步骤
场景说明
当前示例包含4个组件，分别为componentA、componentB、componentC和componentD。
组件依赖关系为：componentD依赖componentB和componentC，componentB和componentC依赖componentA。
现在使用jenkins流水线来编排部署这4个组件，支持单个或多个组件升级而不用考虑依赖关系单个组件依次升级。
配置jenkins流水线
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 $Model_Name| grep -w -o "componentD" || echo "error" ', returnStdout: true).trim()}"
}
stages {
stage('Build componentA') {
//when条件判断当环境变量"_componentA" = "componentA"时，表示构建时选择了该组件，执行此stage，否则跳过此stage
when { environment name: '_componentA', value: 'componentA' }
steps {
sh ''' echo "start to build componentA" '''
script{
//build(job: 'componentA') 表示执行componentA任务，这个任务是jenkins中创建的任务名称，用于componentA组件升级的任务
def componentBuild=build(job: 'componentA')
//打印执行任务的结果
println componentBuild.getResult()
}
}
}
stage('Build parallel jobs') {
//failFast true 表示parallel并行的stage中只要有一个失败，其他并行任务也会中止
//不加failFast true，parallel中失败的stage不会影响其他并行的stage执行，直到所有的并行任务执行完成
//failFast true //按需添加
//parallel 表示里面的stage是并行执行的，只要其中有一个stage执行失败，则"Build parallel jobs"这个stage是失败的，它后续的stage不会执行
parallel {
stage('Build componentB') {
when { environment name: '_componentB', value: 'componentB' }
steps {
sh ''' echo "start to build componentB" '''
script{
def componentBuild=build(job: 'componentB')
println componentBuild.getResult()
}
}
}
stage('Build componentC') {
when { environment name: '_componentC', value: 'componentC' }
steps {
sh ''' echo "start to build componentC" '''
script{
def componentBuild=build(job: 'componentC')
println componentBuild.getResult()
}
}
}
}
}
stage('Build componentD') {
when { environment name: '_componentD', value: 'componentD' }
steps {
sh ''' echo "start to build componentD" '''
script{
def componentBuild=build(job: 'componentD')
println componentBuild.getResult()
}
}
}
}
}
脚本说明
每个组件都需要在pipeline中的envionment获取组件参数，用于判断参数化构建时是否选中，执行下面脚本：
_{component_name}="${sh(script:' echo $Model_Name| grep -w -o "{component_name}" || echo "error" ', returnStdout: true).trim()}"
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()
}
}
}
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。
