visual-studio - 在 VS2019 中调试 Docker-Compose 失败并出现 .Net Core SDK 错误

问题描述

所以，我想在我的一个项目中学习并尝试 Docker-Compose。该项目由 6 个 ASP.Net Core 独立服务组成，均配备了自动生成的 dockerfile。

所有项目都在 .Net Core 3.1 上运行，它们的 dockerfile 也反映了这一点。

dockerfile 示例：

FROM mcr.microsoft.com/dotnet/core/aspnet:3.1-buster-slim AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443

FROM mcr.microsoft.com/dotnet/core/sdk:3.1-buster AS build
WORKDIR /src
COPY .... (Some copies here I did cut out)
RUN dotnet restore "Services/MooMed.Stateful.SessionService/MooMed.Stateful.SessionService.csproj"
COPY . .
WORKDIR "/src/Services/MooMed.Stateful.SessionService"
RUN dotnet build "MooMed.Stateful.SessionService.csproj" -c Release -o /app/build

FROM build AS publish
RUN dotnet publish "MooMed.Stateful.SessionService.csproj" -c Release -o /app/publish

FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "MooMed.Stateful.SessionService.dll"]

VS 然后生成以下 docker-compose.yml：

  moomed.stateful.sessionservice:
    image: ${DOCKER_REGISTRY-}moomedstatefulsessionservice
    build:
      context: .
      dockerfile: Services/MooMed.Stateful.SessionService/Dockerfile

使用相应的 docker-compose.override.yml：

moomed.stateful.sessionservice:
    environment:
      - ASPNETCORE_ENVIRONMENT=Development
      - ASPNETCORE_URLS=https://+:443;http://+:80
    ports:
      - "80"
      - "443"
    volumes:
      - ${APPDATA}/Microsoft/UserSecrets:/root/.microsoft/usersecrets:ro
      - ${APPDATA}/ASP.NET/Https:/root/.aspnet/https:ro

这是我在尝试调试 docker-compose 时得到的错误日志：

请注意，docker-compose 确实运行了所有 6 项服务，我只列出了其中一项的文件，以便将您从文本墙中拯救出来。

但是，所有 dotnet 命令都以相同的方式失败。

我应该注意，当单独从 VS 在 Docker 中运行服务时完全没有问题，它工作得非常好，所以我认为 Dockerfiles 不一定是错误的。尽管我在 docker-compose 中阅读了有关构建部分的内容，但它也应该明确地使用给定的 Dockerfiles，就像我自己做的那样。

那么，这里可能出了什么问题？

编辑：更多信息......与此同时，我还创建了一个新的默认 Asp.Net Core 应用程序，通过 docker-compose 使用 dockerfiles 和 compose yaml 运行它，除了引用之外，它基本上等于这个，并且没有任何问题那里。

EDIT2：现在也尝试docker-compose up手动，这非常有效。这是否与 VS 中的调试组合启动功能所做的 vsdbg 相关联？我的意思是我不知道 Visual Studio 是如何做这些事情的，但可能 VS 将 yaml 转换为包含 vsdbg 的下载，然后将条目 args 提供给启动应用程序的调试器，然后这将失败，因为容器没有有必要的命令。可能是这样的。但是，如果是这种情况，那么在没有 docker-compose 的情况下对单个服务进行正常调试时也会失败。
