Debugging Django in Docker container with VS Code doesn't engage debug inspector

[trentfridey]

Before creating a new issue, please check the FAQ to see if your question is answered there.

Environment data

• debugpy version: 1.6.7
• OS and version:
  • Local: macOS-13.4-arm64-arm-64bit
  • Container: Linux-5.15.49-linuxkit-aarch64-with-glibc2.17
• Python version (& distribution if applicable, e.g. Anaconda): 3.10.4
• Using VS Code or Visual Studio: VS Code

Actual behavior

The application halts on the debugpy.breakpoint() but the debug UI doesn't engage

Expected behavior

The debug UI should have breakpoint line highlighted, call stack populated, and variables populated.

Steps to reproduce:

I have created a minimal project with all the relevant parts here: https://github.com/trentfridey/docker-django-uwsgi-nginx

The project is a Django app running in a Docker container served with NGINX. The NGINX server runs in a separate container from the Django app and talks to it via uWSGI. The entrypoint script kicks off a supervisorctl process that runs uwsgi.

### Tasks

Also I found the debug logs from debugpy running in the minimal project.

I suspect it's because of a path mapping issue, I see you have a custom prefix in your Dockerfile.

{
  "version": "0.2.0",
  "configurations": [
      {
          "type": "debugpy",
          "request": "attach",
          "name": "attach (docker)",
          "connect": {
              "host": "localhost",
              "port": 5678
          },
          "pathMappings": [
              {
                  "localRoot": "${workspaceFolder}",
                  "remoteRoot": "/app"
              }
          ]
      }
  ]
}

I had the same issue, but solved it with this launch.json file

Hi, I guess it's a bit late, but what did you do in the end? 😅
And, if it still doesn't work, does the above work for you?

I don't know, I've moved on from the project
