Jenkins有多個代理的階段-有解無憂

如果我想為特定階段定義代理，我遇到了管道問題。

def call(Map pipelineParams) {
    pipeline {

        environment {
            // Environment variables for Docker
            DOCKERCREDS = credentials('odyssey-artifactory-token')
            COMPONENT = 'listener-publisher-service'
            REGISTRY_PATH = 'com.csg.ops.it.prf'
            REGISTRY = 'docker-dev.odyssey.rowini.net'
        }

        options {
            disableConcurrentBuilds()
            timeout(time: 1, unit: 'HOURS')
        }

        agent none

        stages {
            stage('Docker') {
                agent {
                    label 'docker'
                }
                steps {
                    sh '''
                                docker build -t $REGISTRY/$REGISTRY_PATH/$COMPONENT:$POM_VERSION . --force-rm=true
                                docker login -u $DOCKERCREDS_USR -p $DOCKERCREDS_PSW $REGISTRY
                                docker push $REGISTRY/$REGISTRY_PATH/$COMPONENT:$VERSION
                                docker rmi $REGISTRY/$REGISTRY_PATH/$COMPONENT:$VERSION
                                docker logout $REGISTRY
                    '''
                }
            }
        }
    }
}

我收到以下錯誤：

但是，如果我在階段之外定義代理，我不會收到任何錯誤。

    pipeline {

            DOCKERCREDS = credentials('odyssey-artifactory-token')
            COMPONENT = 'listener-publisher-service'
            REGISTRY_PATH = 'com.csg.ops.it.prf'
            REGISTRY = 'docker-dev.odyssey.rowini.net'
        }

        options {

            timeout(time: 1, unit: 'HOURS')
        }

我檢查了有關 Jenkins 管道語法的檔案，但我的代碼沒有發現任何問題。你知道我做錯了什么嗎？

uj5u.com熱心網友回復：

您會看到此錯誤，因為塊credentials內使用的輔助方法environment需要node給定執行背景關系中的背景關系。您可以通過暫時注釋掉這部分代碼來看到這一點，并且您的初始管道不會因此而失敗。

您可以通過在節點上運行的內部定義environment塊來解決此問題：stagedocker

pipeline {
    environment {
        COMPONENT = 'listener-publisher-service'
        REGISTRY_PATH = 'com.csg.ops.it.prf'
        REGISTRY = 'docker-dev.odyssey.rowini.net'
    }

    options {
        disableConcurrentBuilds()
        timeout(time: 1, unit: 'HOURS')
    }

    agent none

    stages {
        stage('Docker') {
            agent {
                label 'docker'
            }
            environment {
                // Environment variables for Docker
                DOCKERCREDS = credentials('odyssey-artifactory-token')
            }
            steps {
                sh '''
                                docker build -t $REGISTRY/$REGISTRY_PATH/$COMPONENT:$POM_VERSION . --force-rm=true
                                docker login -u $DOCKERCREDS_USR -p $DOCKERCREDS_PSW $REGISTRY
                                docker push $REGISTRY/$REGISTRY_PATH/$COMPONENT:$VERSION
                                docker rmi $REGISTRY/$REGISTRY_PATH/$COMPONENT:$VERSION
                                docker logout $REGISTRY
                    '''
