Cant connect to django process running in container with vs-code

Question

Im having trouble connecting to a django process running inside a container spawned with vs-code. Everything seem to be working and I get the startup message for the server, but when connecting to localhost:8000, I get no response...

I get a published port message when starting the container:

Published Ports: 8000/tcp -> 127.0.0.1:8000

and also a clean start when starting launch.json debug

System check identified no issues (0 silenced). October 13, 2019 - 17:45:05 Django version 2.2.6, using settings 'fpl-django.settings' Starting development server at http://127.0.0.1:8000/ Quit the server with CONTROL-C.

Why cant I access the site on: localhost:8000?

devcontainer.json:

    // For format details, see https://aka.ms/vscode-remote/devcontainer.json or the definition README at
// https://github.com/microsoft/vscode-dev-containers/tree/master/containers/docker-existing-dockerfile

  // Add the IDs of extensions you want installed when the container is created in the array below.
  "extensions": [
    "ms-python.python",
  ]
}

launch.json:

    {
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Python: Django",
      "type": "python",
      "request": "launch",

      "console": "integratedTerminal",
      "args": [
        "runserver",
        "--noreload",
        "--nothreading"
      ],
      "django": true
    }
  ]
}

Hi @TheKaizer, which OS you're using now? With Windows OS, sometime I have to use IP like 192.168.x.x to be able to connect to container. And I also have to run my app using this: "./manage.py runserver 0.0.0.0:8000 --noreload --nothreading" to be able to connect from outside — Toan Quoc Ho

Have you tried using the 'Remote - Container' extension to develop within your container? — Brett Cannon

@ToanQuocHo it worked, do you want to add it as an answer so I can accept it? — Andreas

Try to run manage.py runserver with this param: 0.0.0.0:8000, this will tell your app to listen request from any host. Like so:

{
      "name": "Python: Django",
      "type": "python",
      "request": "launch",
      "program": "${workspaceFolder}/manage.py",
      "console": "integratedTerminal",
      "args": [
        "runserver",
        "0.0.0.0:8000",
        "--noreload",
        "--nothreading"
      ],
      "django": true
}
