构建带有构建参数的停靠机映像并将其从DevOps推送到ACR

问题描述

我正在Azure DevOps管道中构建停靠器映像，然后希望将其推送到Azure容器注册表。注册表已创建，我已将DevOps配置为使用它，buildAndPush Docker task也可以工作。

但是，由于Docker构建可以参数化，我希望将参数传递给它并使用buildAndPushDocker任务。所以我决定分两步来做，一步是建，另一步是推。这边：

# Docker
# Build and push an image to Azure Container Registry
# https://docs.microsoft.com/azure/devops/pipelines/languages/docker
trigger: none

resources:
- repo: self

variables:
  # Container registry service connection established during pipeline creation
  dockerRegistryServiceConnection: 'aaaa-aaaa-aaaa-aaaa-aaaaa'
  imageRepository: 'ubuntu-qt'
  containerRegistry: 'myregistry.azurecr.io'
  dockerfilePath: '$(Build.SourcesDirectory)/docker-qt-build/Dockerfile'

  # Agent VM image name
  vmImageName: 'ubuntu-latest'

stages:
- stage: BuildPush
  displayName: Build and push
  jobs:
  - job: Build
    displayName: Build
    pool:
      vmImage: $(vmImageName)
    steps:
    - task: Docker@2
      displayName: Build ubuntu with qt 5.12.4 installed
      inputs:
        command: build
        repository: $(imageRepository)
        dockerfile: $(dockerfilePath)
        tags: 5.12.4
        arguments: '--build-arg ubuntu_version=18.04 --build-arg qt_version_major=5.12 --build-arg qt_version_full=5.12.4'
    - task: Docker@2
      displayName: Push ubuntu with qt 5.12.4 installed
      inputs:
        command: push
        repository: $(imageRepository)
        containerRegistry: $(dockerRegistryServiceConnection)
        tags: myregistry.azurecr.io/ubuntu-qt:5.12.4

即使构建任务运行良好，似乎也找不到要推送到注册表的镜像：

    Finishing: Push ubuntu with qt 5.12.4 installed

推荐答案

在构建步骤中也指定containerRegistry，并在推送步骤中使用5.12.4FORtags(而不是myregistry.azurecr.io/ubuntu-qt:5.12.4)。

这样：

steps:
- task: Docker@2
  displayName: Build ubuntu with qt 5.12.4 installed
  inputs:
    command: build
    repository: $(imageRepository)
    containerRegistry: $(dockerRegistryServiceConnection)
    dockerfile: $(dockerfilePath)
    tags: 5.12.4
    arguments: '--build-arg ubuntu_version=18.04 --build-arg qt_version_major=5.12 --build-arg qt_version_full=5.12.4'
- task: Docker@2
  displayName: Push ubuntu with qt 5.12.4 installed
  inputs:
    command: push
    repository: $(imageRepository)
    containerRegistry: $(dockerRegistryServiceConnection)
    tags: 5.12.4
