具有多容器并使用 Docker-Compose 设置的 Azure WebApp 在开发计算机上成功运行，但在 Azure 上出现错误

Question

我正在使用简单的 docker-compose 设置来学习 azure 和 github ci/cd，该设置在我的开发计算机上完美运行，但在 Azure WebApp 上不断失败，并出现以下错误：

2024-09-04T16:12:01.352714815Z The command could not be loaded, possibly because:

在进一步检查部署中心/容器日志中的日志时，我发现 WebApp 内部甚至没有调用 docker-compose up 来启动容器，这些容器在我的开发计算机上运行得很好，而是运行以下命令：

我的示例 Docker-Compose 文件

        ports:
            - "80:5104"
        volumes:

我的 GitHub 工作流程文件：

      with:
        app-name: ${{ env.AZURE_WEBAPP_NAME }}
        configuration-file: 'docker-compose.yml'

我的问题是：

1. 考虑到我正在使用 github 工作流程来构建图像，将其推送到 acr，然后在所有托管在同一订阅中的 webapp 上运行 docker-compose，是否有更好的方法来做到这一点？
2. 关于如何进一步解决当前设置问题的任何想法，因为这是一个非常简单的用例，.net MVC Core 应用程序作为 web，sqlserver 作为数据库，所有这些都在 docker 上运行。
3. 为什么 WebApp 没有在容器日志中运行 docker-compose up :)

Answer 1

我使用 docker compose 创建了一个示例多容器应用程序，并通过 GitHub 部署到 ACR。

• 我已引用此doc并创建了应用程序。

• 感谢 @alaintd 的清晰解释，我已参考此 doc 使用 GitHub 操作构建 Docker 映像并将其推送到 Azure 容器注册表。

• 确保在 GitHub 存储库设置 -> 机密和变量 -> 操作 -> 新存储库机密中添加 Azure 容器注册表凭据。

• 我已将以下代码行添加到我的工作流程文件中以登录 Azure 容器注册表。

 name: Azure Container Registry Login
        uses: Azure/docker-login@v1
        with:
          login-server: multiappregis.azurecr.io
          username: ${{ secrets.ACR_USERNAME }}
          password: ${{ secrets.ACR_PASSWORD }}

我完整的工作流程文件：

name: Build and Push Docker Images
on:
  push:
    branches:
      - main
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout repository
        uses: actions/checkout@v3
      - name: Azure Container Registry Login
        uses: Azure/docker-login@v1
        with:
          login-server: multiappregis.azurecr.io
          username: ${{ secrets.ACR_USERNAME }}
          password: ${{ secrets.ACR_PASSWORD }}
      - name: Build and push the first image (app)
        uses: docker/build-push-action@v2
        with:
          context: ./multiapp 
          file: ./multiapp/Dockerfile 
          push: true
          tags: <ACR-NAME>.azurecr.io/app:latest
      - name: Build and push the second image (db)
        uses: docker/build-push-action@v2
        with:
          context: ./multiapp 
          file: ./multiapp/Dockerdb/Dockerfile 
          push: true
          tags: <ACR-NAME>.azurecr.io/db:latest

• 通过 GitHub Actions 成功将映像部署到 Azure 容器注册表后。
• 我使用 Azure 容器注册表进一步将应用程序部署到 Azure 应用服务

输出：
