c# - Azure DevOps Docker 在管道中构建并在版本中推送 Docker

Question

我们在 Azure DevOps 中使用构建和发布管道。

我可以在构建管道中构建并推送 Docker 容器，如下所示:

- task: Docker@2
inputs:
    containerRegistry: 'MyContainerRegistry'
    repository: 'classificationapi'
    command: 'buildAndPush'
    Dockerfile: 'src\Services\Classification\ClassificationService.Api\Dockerfile'
    buildContext: ''

我已在 Azure 容器注册表中验证它是否有效。

但是我不想在每个构建中推送 Docker 镜像。

https://learn.microsoft.com/en-us/azure/devops/pipelines/ecosystems/containers/acr-template?view=azure-devops

我想在发布管道运行时推送构建的 Docker 镜像。

我可以像这样从工件中使用 buildAndPush 。

steps:
- task: Docker@2
  displayName: 'buildAndPush - classificationapi'
  inputs:
    containerRegistry: MyContainerRegistry
    repository: classificationapi
    Dockerfile: '$(System.DefaultWorkingDirectory)/_Project/Src-DockerContent/src/Services/Classification/ClassificationService.Api/Dockerfile'
    buildContext: '$(System.DefaultWorkingDirectory)/_Project/Src-DockerContent'

这会产生这样的错误。

但是这对我们来说也不理想。我想在构建管道中使用 Docker 构建，并在运行发布管道时使用 Docker Push。这可能吗？

如果我尝试仅在发布中进行推送并尝试使用标签 $(Build.BuildId) 查找图像(标签在构建和发布中均设置)，则它不起作用，因为预计。

Answer 1

构建

您需要在构建管道中构建它，使用docker save将其存储为tar文件，然后将tar文件作为管道工件上传。

    steps:
    - task: Docker@2
      displayName: Build
      inputs:
        containerRegistry: 'My registered registry'
        repository: 'repo/image'
        command: 'build'
        Dockerfile: '$(Build.SourcesDirectory)/PathTo/Dockerfile'
        buildContext: '$(Build.SourcesDirectory)'
        tags: |
          dev-latest
          $(Build.BuildNumber)
          $(Build.BuildId)
    - task: Bash@3
      displayName: Save Docker Image
      inputs:
        targetType: 'inline'
        script: |
          docker save -o $(Build.ArtifactStagingDirectory)/image.tar image:$(Build.BuildNumber)
    - task: PublishPipelineArtifact@1
      inputs:
        targetPath: '$(Build.ArtifactStagingDirectory)/image.tar'
        artifact: 'my-artifact'
        publishLocation: 'pipeline'

发布

然后在您的版本中，使用代理池创建一个包含代理的阶段，该代理池可以访问您要发布到的注册表。然后，添加两个任务；一个 bash 任务将保存的镜像 tar 加载到当前 docker 中，然后一个 docker 任务将其推送到注册表。

(发布任务的yaml输出)

steps:
- bash: |
   docker load --input $(Agent.ReleaseDirectory)/_BuildArtifact/my-artifact/image.tar
  displayName: 'Load container from build'
- task: Docker@2
  displayName: 'Push to Regitry'
  inputs:
    containerRegistry: 'My registered registry'
    repository: 'repo/image'
    command: push
    tags: |
     dev-latest
     $(Build.BuildNumber)
     $(Build.BuildId)
