jenkins管道传递变量

我有一个管道，我正在通过一个docker容器构建我的图像，它输出图像标签，我想把图像标签传递到下一个阶段，当我在下一个阶段回显它时，它会打印出来。但当我把它放在壳里时，它就空了。这是我的管道

pipeline {
  agent any
  stages {
    stage('Cloning Git') {
      steps {
      git( url: 'https://xxx@bitbucket.org/xxx/xxx.git',
            credentialsId: 'xxx',
            branch: 'master')

      }
    }
    stage('Building Image') {
      steps{
         script {
         env.IMAGE_TAG = sh script: "docker run -e REPO_APP_BRANCH=master -e REPO_APP_NAME=exampleservice -e DOCKER_HUB_REPO_NAME=exampleservice --volume /var/run/docker.sock:/var/run/docker.sock registry.xxxx/build", returnStdout: true

        }
      }
    }

    stage('Integration'){
      steps{
        script{
                echo "passed: ${env.IMAGE_TAG}"
          sh """
            helm upgrade exampleservice charts/exampleservice --set image.tag=${env.IMAGE_TAG}
            """
            sh "sleep 5"


        }
      }
    }

  }
}

管道输出

[Pipeline] }
[Pipeline] // script
[Pipeline] }
[Pipeline] // stage
[Pipeline] stage
[Pipeline] { (Integration)
[Pipeline] script
[Pipeline] {
[Pipeline] echo
passed:

[Pipeline] sh

获取空图像标记

您应该使用“env”覆盖此设置

用以下代码替换您的代码：

pipeline {
  agent any
  stages {
    stage('Cloning Git') {
      steps {
      git( url: 'https://xxx@bitbucket.org/xxx/xxx.git',
            credentialsId: 'xxx',
            branch: 'master')

      }
    }
    stage('Building Image') {
      steps{
         script {
         env.IMAGE_TAG = sh script: "docker run -e REPO_APP_BRANCH=master -e REPO_APP_NAME=exampleservice -e DOCKER_HUB_REPO_NAME=exampleservice --volume /var/run/docker.sock:/var/run/docker.sock registry.xxxx/build", returnStdout: true

        }
      }
    }

    stage('Integration'){
      steps{
        script{
                echo "passed: ${env.IMAGE_TAG}"
          sh """
            helm upgrade exampleservice charts/exampleservice\            
            --set image.tag="${env.IMAGE_TAG}"
            """
            sh "sleep 5"


        }
      }
    }

  }
}

我在sh中的env.IMAGE_标记仍为空值，但echo正在工作我已使用管道输出编辑了我的问题我已编辑了我的答案。不应在“sh”部分中添加“env.”前缀
