简单的jenkins docker管道构建

我正在尝试使用jenkins文件构建一个简单的jenkins docker管道

我遇到的问题是，我想在将图像推送到存储库之前测试它，但我不知道如何在阶段或步骤之间保持引用。我尝试在顶部添加def app=null，但仍然出现相同的错误

def app = null
pipeline {
  agent {
    node {
      label 'master'
    }

  }
  stages {
    stage('Clone repository') {
      steps {
        checkout scm
      }
    }
    stage('Build image') {
      steps {
        script {
            app = docker.build("socketserver")
        }
      }
    }
    stage('Test image') {
      steps {
        script {
          app.inside { 
            sh 'echo "Tests passed"'
          }
        }

      }
    }
    stage('Push image') {
      steps {
        script {
          docker.withRegistry('http://localhost:5000') {
            app.push("${env.BUILD_NUMBER}")
            app.push("latest")
          }
        }
      }
    }
  }
}

这是错误日志。与全局变量相关的主要错误：groovy.lang.MissingPropertyException:没有此类属性：app for class:groovy.lang.Binding

您是否尝试使用

此.app.inside

？这可能会有帮助。@Amit你是个天才。请提交答案，以便我能给出正确答案：）
