docker - 如何使用 DevOps 管道部署多个微服务

问题描述

我正在尝试使用 DevOps 将两个 .Net Core 应用程序部署到 Azure Kubernetes。默认管道仅构建和部署我添加的第一个项目。

我创建了一个包含两个解决方案文件夹的单个解决方案，每个文件夹都包含一个 .Net Core 项目。我为这两个项目添加了编排支持，并使用 DevOps 中的“向导”创建了一个 Azure 管道。我在成功部署第一个项目后添加了辅助项目。我认为问题存在是因为 Docker Registry Service Connection 不包含新项目，所以我删除了它并重新创建了连接，但它仍然只部署了第一个项目。我正在使用 Azure Git。

azure-pipeline.yaml 非常标准。我已接受创建管道时创建的默认值。这是我的 buildAndPush 阶段。

stages:
- stage: Build
  displayName: Build stage
  jobs:  
  - job: Build
    displayName: Build job
    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)
    - task: PublishPipelineArtifact@0
      inputs:
        artifactName: 'manifests'
        targetPath: 'manifests'

我如何让它来构建和部署其他剩余的项目？

解决方案

我已经设法使用单个 azure-pipelines.yml 文件部署了两个项目；但是，我几乎可以肯定这是不正确的。我为每个项目复制了构建阶段，并指定了两个单独的 Dockerfile。另外，我为每个项目添加了一个deployment.yml 和service.yml 文件。请参阅下面的 azure-pipelines.yml。任何有关如何正确执行此操作的建议将不胜感激。
