azure - 在 Azure DevOps 中将 Docker 容器标记为最新

Question

我正在尝试构建一个 Docker 容器并将其推送到 Azure 容器注册表。为此，我创建了这个 azure-pipeline.yml

# Docker
# Build and push an image to Azure Container Registry
# https://learn.microsoft.com/azure/devops/pipelines/languages/docker

trigger:
- main

resources:
- repo: self

variables:
  # Container registry service connection established during pipeline creation
  dockerRegistryServiceConnection: '...'
  imageRepository: 'mycontainer'
  containerRegistry: 'azuk.azurecr.io'
  dockerfilePath: '$(Build.SourcesDirectory)/dockerfile'
  tag: '$(Build.BuildId)'

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

stages:
- stage: Build
  displayName: Build and push stage
  jobs:
  - job: Build
    displayName: Build
    pool:
      vmImage: $(vmImageName)
    steps:
    - task: Docker@2
      displayName: Build and push an image to container registry
      inputs:
        command: buildAndPush
        repository: $(imageRepository)
        dockerfile: $(dockerfilePath)
        containerRegistry: $(dockerRegistryServiceConnection)
        tags: |
          $(tag)

管道正在运行。现在，我有另一个 Azure 管道来构建另一个容器，但基础是第一个容器。为此，我在 Dockerfile 的第一行添加了

FROM azuk.azurecr.io/mycontainer

当管道启动时，我收到错误

manifest for ***/mycontainer:latest not found: manifest unknown: manifest tagged by "latest" is not found

我找不到一种方法来告诉 ACR 最后推送的是最新版本。我看到一些帖子使用了不再存在的属性 includeLatestTag

- stage: Build
  displayName: Build image
  jobs:  
  - job: DockerImage
    displayName: Build and push Docker image
    steps:
    - task: Docker@1
      displayName: 'Build the Docker image'
      inputs:
        containerregistrytype: 'Container Registry'
        dockerRegistryEndpoint: 'Docker Hub'
        command: 'Build an image'
        dockerFile: '**/Dockerfile'
        imageName: '$(ImageName)'
        includeLatestTag: true
        useDefaultContext: false
        buildContext: '.'

如何将标签 latest 添加到 Docker 容器并通过 Azure DevOps 管道将其推送到 Azure 容器注册表？

这对我来说很有用，Enrico，它会覆盖存储库中的“最新”版本，并根据 BuildID 创建一个新的独立版本。

希望对你有帮助...

- task: Docker@2
  displayName: 'Build & Push image to $(container.registry) container registry'
  inputs:
    containerRegistry: '$(container.registry)'
    repository: '$(container.repository)'
    Dockerfile: '**/Dockerfile'
    command: 'buildAndPush'
    tags: |
      latest
      $(Build.BuildId)
