jenkins管道:如何在代理列表上并行执行功能? [英] jenkins pipeline : How to execute a function on a list of agents in parallel?

问题描述

我有一堆服务于标签rhel6，rhel7的节点.

I have a bunch of nodes serving labels rhel6, rhel7.

如何在rhel6的任意2个节点和rhel7-的任意3个节点上并行执行myFunc()?

How do I execute myFunc() on any 2 nodes of rhel6 and any 3 nodes rhel7 - in parallel?

def slaveList = ['rhel6', 'rhel6', 'rhel7', 'rhel7', 'rhel7']

def stageFunc (String slaveLabel) {
  return {
        // Run this stage on any available node serving slaveLabel
        agent { label "${slaveLabel}" } // Error shown here.
        stage {
            myFunc()
        }
    } 
}

pipeline {
    agent any

    stages {
        stage('Start') {
            steps {
                script {
                    def stageMap = [:]
                    def i = 0
                    slaveList.each { s ->
                        stageMap[i] = stageFunc(s)
                        i++
                    }
                    parallel stageMap
                }
            }
        }        
    }
}

显示的错误: java.lang.NoSuchMethodError: No such DSL method 'agent' found among steps [archive, ...

推荐答案

我尚未对此进行测试，但应该可以.

I haven't tested this yet, but it should work.

def slaveList = ['rhel6', 'rhel6', 'rhel7', 'rhel7', 'rhel7']

def stageFunc (stage_name, slaveLabel) {
  return {
        // Run this stage on any available node serving slaveLabel
        stage(stage_name){
            node(slaveLabel) {   
                myFunc()
            }
        }

    } 
}

pipeline {
    agent any

    stages {
        stage('Start') {
            steps {
                script {
                    def stageMap = [:]
                    def i = 0
                    slaveList.each { s ->
                        stageMap[i] = stageFunc("Stage-${i}", s)
                        i++
                    }
                    parallel stageMap
                }
            }
        }        
    }
}
