如何使用VisualStudio2019在Docker容器中运行ASP.NET Core3.1项目？
如何使用VisualStudio2019在Docker容器中运行ASP.NET Core3.1项目？
提问于 2020-01-03 00:09:51
我创建了一个基于ASP.NET Core3.1框架的Web项目。后来，我决定将它部署在Linux上，而不是Windows上。在将应用程序部署到Linux上之前，我希望能够在本地使用Windows 7上的VisualStudio2019在停靠容器中运行。
我在我的机器上安装了用于窗口的码头工具箱和Oracle。
由于我的项目不是用Docker创建的，所以我正确地单击了我的项目>> Add >> "Add“支持，该支持创建了Dockerfile。
现在，当我尝试在Visual上构建/调试我的应用程序时，我会得到以下错误
Error CTC1003 Visual Studio container tools require Docker to be running. ProjectName C:\Users\MyUsername\.nuget\packages\microsoft.visualstudio.azure.containers.tools.targets\1.9.10\build\Container.targets 198 我通过点击“码头快速启动终端”启动了码头。我还能够验证default虚拟盒是否正在运行。此外，我在默认VM上添加了"C_Drive“作为共享文件夹。
如何使用docker正确启动/调试解决方案？
这里是我的Dockerfile的内容
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 ["ProjectName/ProjectName.csproj", "ProjectName/"]
RUN dotnet restore "ProjectName/ProjectName.csproj"
COPY . .
WORKDIR "/src/ProjectName"
RUN dotnet build "ProjectName.csproj" -c Release -o /app/build
FROM build AS publish
RUN dotnet publish "ProjectName.csproj" -c Release -o /app/publish
FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "ProjectName.dll"]我还试图通过右键单击我的项目>>添加>>添加容器Orchestraintor支持哪个docker-compose项目来添加docker-compose支持。
当我使用Docker Composer运行该应用程序时，该应用程序运行Visual时，会为调试状态转橙色“并立即停止。

按照下面的Wiebe Tijsma答案，我将docker-composer.yml文件更新为
version: '3.4'
services:
myproject:
image: ${DOCKER_REGISTRY-}myproject
build:
context: .
dockerfile: MyProject/Dockerfile
volumes:
- photos:/app/Storage
volumes:
photos:构建现在似乎运行良好，但运行失败。使用docker-composer运行应用程序时，Visual将引发此错误。
启动失败，因为容器中的目录‘/remote_调试器’是空的。这可能是由于Desktop使用的共享驱动器凭据过期造成的。尝试在Desktop设置的共享驱动器页面中重置凭据，然后重新启动Docker

在我的示例中，发生此错误是因为我还将卷映射到/app，这导致入口点+所有dotnet发布的文件不可用(初学者错误：)。
myapp:
container_name: myapp
image: watch/myapp
volumes:
- ./testdata/:/app #<-- wrongStack Overflow用户

您可以运行docker-compose并按如下方式启动项目：
services:
xxxx.service:
image: ${DOCKER_REGISTRY}orderservice
build:
context: .
dockerfile: Dockerfile`这是莱克-作曲家的位置
