我正在Azure DevOps管道中构建一个docker映像，然后我想将其推送到Azure容器注册表。注册表已经创建，我已经配置了DevOps来使用它，buildAndPushDocker任务也可以工作。
然而，由于Docker构建可以参数化，所以我想向它传递参数，而不能使用buildAndPushDocker任务。所以我决定分两步来做，一步是建设，另一步是推进。这样：
# Docker
# Build and push an image to Azure Container Registry
# https://learn.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，它似乎也无法找到推送到注册表的映像：

Finishing: Push ubuntu with qt 5.12.4 installed
在构建步骤中也指定containerRegistry，并在推送步骤中使用5.12.4代替tags(而不是myregistry.azurecr.io/ubuntu-qt:5.12.4(。
像这样：
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: $(dockerRegistryServiceConnection)
tags: 5.12.4
有人问了一个关于如何用一个构建推送到多个注册中心的问题。为了做到这一点，您需要为每个存储库别名(通过docker标记(本地映像。
steps:
- task: Docker@2
displayName: Build
inputs:
command: build
repository: myimage
dockerfile: myimage.dockerfile
# note no containerRegistry here
buildContext: '$(Build.SourcesDirectory)'
tags: latest
- task: CmdLine@2
displayName: Alias registry1.io
inputs:
script: docker tag myimage:latest registry1.io/myimage:latest
- task: Docker@2
displayName: Push registry1.io
inputs:
command: push
repository: myimage
containerRegistry: registry1.io
tags: latest
- task: CmdLine@2
displayName: Alias registry2.io
inputs:
script: docker tag myimage:latest registry2.io/myimage:latest
- task: Docker@2
displayName: Push registry2.io
inputs:
command: push
repository: myimage
containerRegistry: registry2.io
tags: latest
