docker - Jenkins 管道即代码，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 镜像并将其推送到我的 Docker Hub。该项目是一个带有 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 Jenkins 服务器运行此程序时，出现以下错误:

由于这是在 Azure 上的虚拟机内运行，我认为虚拟机无法访问外部，但事实似乎并非如此，因为我能够 ssh 进入虚拟机并从 Git 存储库中进行 git pull。那么这里有什么问题呢？我怎样才能做到这一点？

对我来说，取消选中“轻量级结帐”解决了问题
