【问题描述】：

我正在尝试在构建和部署 docker 映像之前将视频文件从 GPM 复制到 app/dist/asset/images 文件夹。在第 27 行获取意外值“步骤”。

如果我删除复制视频文件的步骤，YML 文件可以正常工作。

azure-pipelines.yml

    trigger:
  branches:
    include: ['*']

pool:
  name: Default

# templates repo
resources:
  repositories:
    - repository: templates
      type: git
      name: comp.app.common.devops-templates
      ref: master

# Global Variables
variables:
  # necessary variables defined in this template
  - template: azure-templates/vars/abc-vars.yml@templates
  - name: dockerRepoName
    value: 'docker-it/library/xyz'
  # needed for k8 deployment
  - name: helmReleaseName
    value: xyz

stages:
  - steps:
    - bash: 'curl -o aa.mp4 https://gpm.mmm.com/endpoints/Application/content/xyz/bb.mp4'
      workingDirectory: '$(System.DefaultWorkingDirectory)/_hh_app/drop/app/dist/assets/images'
      displayName: 'Download Assets'

  # template to build and deploy
  - template: azure-templates/stages/angular-express-docker.yml@templates
    parameters:
      dockerRepoName: $(dockerRepoName)

    # deploy to rancher
  - template: azure-templates/stages/deploy-k8-npm.yml@templates
    parameters:
      helmReleaseName: $(helmReleaseName)

【解决方案1】：

steps 属性不应置于stage 级别之下。它是：stage=>job=>steps

因此，当您定义多阶段 yaml 管道时，您不能将 steps 放在那里。

1.steps 可以直接放在第一级，用于简单的 yaml 管道（无阶段）：

trigger:
- master

pool:
  vmImage: 'windows-latest'

steps:
- script: echo Hello, world!
  displayName: 'Run a one-line script'

- script: |
    echo Add other tasks to build, test, and deploy your project.
  displayName: 'Run a multi-line script'

2.它应该放在多阶段yaml管道中的作业级别：

stages:
- stage: build
  displayName: Build
  jobs:
  - job: Build
    pool:
      name: xxx
    steps:
      - task: CmdLine@2
        inputs:
          script: |
            echo Hello world

- stage: deploy
  displayName: Release
  jobs:
  - job: Release
    pool:
      name: xxx
    steps:
      - task: CmdLine@2
        inputs:
          script: |
            echo Hello world

根据您的stages: 元素，您的管道将被识别为可用于构建和部署的多阶段管道。所以你不能也不应该把steps直接放在stages:下面。

解决方案：

要解析Unexpected value 'Steps'，您应该删除steps 或将它们添加到一个阶段级别：

stages:
  - stage: First
    displayName: FirstStage
    jobs:
    - job: FirstJob
      pool:
        name: xxx
      steps:
      - bash: 'curl -o aa.mp4 https://gpm.mmm.com/endpoints/Application/content/xyz/bb.mp4'
        workingDirectory: '$(System.DefaultWorkingDirectory)/_hh_app/drop/app/dist/assets/images'
        displayName: 'Download Assets'

  # template to build and deploy
  - template: azure-templates/stages/angular-express-docker.yml@templates
    parameters:
      dockerRepoName: $(dockerRepoName)

    # deploy to rancher
  - template: azure-templates/stages/deploy-k8-npm.yml@templates
    parameters:
      helmReleaseName: $(helmReleaseName)
