如何在Django Docker容器上指定VSCODE调试器的端口？

Question

我在Docker容器内有一个Django应用程序。我已经配置了启动。 launch.json

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Docker: Python - Django",
            "type": "docker",
            "request": "launch",
            "preLaunchTask": "docker-run: debug",
            "python": {
            "pathMappings": [
                    {
                        "localRoot": "${workspaceFolder}/src",
                        "remoteRoot": "/app/src"
                    }
                ],
             "projectType": "django",
             "port": 8000,
            }
        }
    ]
}

tasks.json

{
    "version": "2.0.0",
    "tasks": [
        {
            "type": "docker-build",
            "label": "docker-build",
            "platform": "python",
            "dockerBuild": {
                "tag": "vscodedjangodocker:latest",
                "dockerfile": "${workspaceFolder}/Dockerfile",
                "context": "${workspaceFolder}",
                "pull": true
            }
        },
        {
            "type": "docker-run",
            "label": "docker-run: debug",
            "dependsOn": [
                "docker-build"
            ],
            "python": {
                "args": [
                    "runserver",
                    "0.0.0.0:8000",
                    "--nothreading",
                    "--noreload"
                ],
                "file": "manage.py"
            }
        }
    ]
}

docker-compose.yaml

version: '3.8'  # Specify the version at the top
services:
  backend:
    build: 
      context: .
      dockerfile: ./Dockerfile
    container_name: backend
    command: python manage.py runserver 0.0.0.0:8000
    ports:
      - 8000:8000
    volumes:
      - .:/app

dockerfile

FROM python:3.12-bullseye

WORKDIR /app/src/

COPY ./src/requirements.txt .

RUN pip install --prefer-binary -r requirements.txt

COPY ./src /app/src

EXPOSE 8000

CMD ["python", "manage.py", "runserver", "0.0.0.0:8000"]

我面临的问题是，我希望调试器会话在本地计算机上的端口8000上运行，但是每次我运行调试器时，打开的端口为5500X（即55001，55002等）。例如，当我单击VSCODE上的“开始调试”按钮时，构建的容器将在端口55012：8000.上运行。 当我只运行Docker与docker组成

docker-compose ---build

命令，它可以按预期运行，并且服务器在我的机器的端口8000上运行，但没有附加的调试器。

如何指定我要在端口8000上会话的VSCODE调试器？

我认为您必须将"port": 8000添加到这样的键：
