docker - 使用实时观察在 VS Code 中调试 dockerize ASP.Net Core 应用程序

Question

我正在尝试在 VS Code 中设置 dockerize ASP.Net Core WebAPI 应用程序的调试。我能够调试应用程序。 但是，我无法设置实时监视，只要主机中的源文件发生更改，docker 应用程序就会重建并更新源映射文件并重新附加调试器。 目前，每次更改源文件时，我都需要手动重新启动调试。

文件夹结构:

development.docker 文件:

FROM microsoft/dotnet:2.2-sdk as DEV
COPY ["CoreApi.csproj", "src/CoreApi.csproj"]
RUN dotnet restore "src/CoreApi.csproj"
RUN apt-get update
RUN apt-get install -y curl unzip
RUN apt-get install -y procps
RUN curl -sSL https://aka.ms/getvsdbgsh | bash /dev/stdin -v latest -l /publish/vsdbg
ENV DOTNET_USE_POLLING_FILE_WATCHER 1
WORKDIR /src
COPY . .
EXPOSE 80
ENTRYPOINT ["dotnet", "watch", "run", "--urls=http://+:80"]

.vscode/task.json:

{
  "version": "2.0.0",
  "tasks": [
    {
      "label": "build",
      "command": "dotnet",
      "type": "process",
      "args": [
        "build",
        "${workspaceFolder}/CoreApi/CoreApi.csproj",
        "/property:GenerateFullPaths=true",
        "/consoleloggerparameters:NoSummary"
      ],
      "problemMatcher": "$msCompile"
    }
  ]
}

.vscode/launch.json:

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "API Launch (Docker Watch)",
      "type": "docker-coreclr",
      "request": "launch",
      "preLaunchTask": "build",
      "dockerBuild": {
        "dockerfile": "${workspaceFolder}/CoreApi/.docker/development.dockerfile",
        "context": "${workspaceFolder}/CoreApi",
        "target": "DEV"
      },
      "appProject": "${workspaceFolder}/CoreApi/CoreApi.csproj",
      "dockerRun": {
        "ports": [
          {
            "hostPort": "5001",
            "containerPort": "80"
          }
        ],
        "volumes": [{ "localPath": "${workspaceFolder}/CoreApi/", "containerPath": "/src" }]
      }
    }
  ]
}

目前看来是不可能的。这是 vscode-docker github repo 中关于此案例的未解决问题。
