Jenkins管道为代码，但出现Docker错误

Question

对于我在GitHub上的一个项目，我想将其构建为docker映像并将其推送到我的docker hub。该项目是一个具有Scala代码库的sbt项目。

这是我的JenkinsFile的定义方式：

#!groovy

node {
  // set this in Jenkins server under Manage Jenkins > Credentials > System > Global Credentials
  docker.withRegistry('https://hub.docker.com/', 'joesan-docker-hub-credentials') {
    git credentialsId: '630bd271-01e7-48c3-bc5f-5df059c1abb8', url: 'https://github.com/joesan/monix-samples.git'

    sh "git rev-parse HEAD > .git/commit-id"
    def commit_id = readFile('.git/commit-id').trim()
    println comit_id

    stage "build" {
      def app = docker.build "Monix-Sample"
    }

    stage "publish" {
      app.push 'master'
      app.push "${commit_id}"
    }
  }
}

当我尝试从我的Jenkins服务器运行此文件时，出现以下错误：

由于这是在Azure上的VM内运行的，因此我认为VM无法到达外部，但事实并非如此，因为我能够通过SSH进入VM并从Git存储库中进行git pull了。那么这是什么问题呢？我该如何进行这项工作？

对我来说，取消选中“轻量级结帐”可解决此问题
