为易于使用的环境配置VS Code。我想有一种简单的方法来在Docker中启动Python脚本并附加调试器。

我有什么用处？

1. 创建了Dockerfile和docker-compose.yaml以正确运行 docker-compose up | start 。
2. 我能够附加到正在运行的 Docker容器并调试我的代码。

我想得到什么？

一个按钮可一次启动并附加。

我需要使用docker-compose启动应用程序。我不想在VS Code中配置docker-run任务。

我的代码和想法：

Dockerfile：

  void updateBalanceOfSender() async {
    var docID;
    Firestore.instance
        .collection('balance')
        .where('user',isEqualTo: loggedInUser.email)
        .snapshots()
        .listen((data) =>
            data.documents.forEach((doc) => print(docID = doc.documentID)));
    _firestore
        .collection('balance')
        .document(docID)
        .updateData({'balance': '1'});
  }

docker-compose.yaml

FROM python:3.6-alpine
RUN mkdir -p /work/
WORKDIR /work/
COPY ./python/requirements.txt ./requirements.txt
RUN pip install --no-cache-dir -r requirements.txt
COPY ./python/src/ .
CMD python -m ptvsd --host 0.0.0.0 --port 5678 --wait run.py < tests/input.txt > tests/output.txt

launch.json配置：

version: "3.7"
services:
    py-service:
        container_name: py-container
        image: py-image
        build:
            context: ./
        volumes:
            - ./python/src/:/work
        ports:
            - 5678:5678

tasks.json以运行docker-compose命令

   { // simple attach to running container - works good
        "name": "Python Attach","type": "python","request": "attach","pathMappings": [
            {
                "localRoot": "${workspaceFolder}/python/src/","remoteRoot": "/work/"
            }
        ],"port": 5678,"host": "127.0.0.1"
    },{ // launch docker container and attach to debugger - NOT works
        "name": "Run Py in Docker","type": "docker","request": "launch","platform": "python","preLaunchTask": "docker-compose-start","python": {
            "pathMappings": [
                {
                    "localRoot": "${workspaceFolder}/python/src/","remoteRoot": "/work/"
                }
            ],"projectType": "general","host": "127.0.0.1",},

问题在于在Docker中执行 Run Py 通常会启动我的容器，但无法附加调试器，并且超时后失败。当容器仍在运行并等待附件时。可以通过某种方式解决此问题吗？

更新

最后，我能够启动和调试了！这是我的 task.json ：

{
  "label": "docker-compose-start","type": "shell","command": "docker-compose up"
},

launch.json ：

{
  "label": "docker-compose-start","command": "docker-compose up --build -d","isBackground": true,"problemMatcher": [
    {
      "pattern": [{ "regexp": ".","file": 1,"location": 2,"message": 3,}],"background": {
        "activeonStart": true,"beginsPattern": "^(Building py-service)$","endsPattern": "^(Creating|Recreating|Starting) (py-container) ... (done)$",}
    },],

毕竟，在将所有docker up | build输出显示为问题中给我带来了不便。 VS Code每次都要求继续，但是 Enter 帮助。
