node.js - Node VS Code 除錯器在 Docker 中顯示未綁定的斷點

經過多次探索，我讓 ts 調試器對特定端口工作，並且在使用 nodemon 進行即時重載時還需要編譯 .ts。我在不使用 docker 運行應用程式時也遇到了相同的未綁定斷點，但修改啟動文件後，它就能工作了。

然而在 Docker 中，除錯器已經附加上去，但斷點是未綁定的。需要對 "name": "my-service-docker", 的啟動檔進行哪些更改以啟用除錯器？

Docker 文件

FROM node:16
WORKDIR /usr/src/app
COPY package*.json ./
RUN npm install
ENV PATH=/usr/src/app/node_modules/.bin:$PATH
If you are building your code for production
RUN npm ci --only=production
COPY . .
EXPOSE 3000
CMD [ "npm", "run", "start:dev" ]

對於 Docker，我們需要為 remoteRoot 設置正確的路徑：即 /usr/src/app

 {
            "name": "my-service-docker",
            "type": "node",
            "request": "attach",
            "port": 9230,
            "restart": true,
            "sourceMaps": true,
            "address": "localhost",
            "localRoot": "${workspaceFolder}",
            "remoteRoot": "/usr/src/app",
            "protocol": "inspector"
        }
