install Python extension for Visual Studio Code

Install VSCode python library. Reopen VSCode after install.

docker-compose

Django project needs to allow port 3000 to use remote debug, so write - "3000:3000".

 web:
    build: .
    command: python manage.py runserver 0.0.0.0:8000
    volumes:
      - .:/code
    ports:
      - "8000:8000"
      - "3000:3000"
    depends_on:
      - db

my sample docker-compose.yml

launch.json

Create file .vscode/launch.json. Port sets 3000. [your docker project remote root path] changes yourself.

{ "version": "0.2.0", "configurations": [ { "name": "Python: Django", "type": "python", "request": "attach", "port": 3000, "host": "localhost", "pathMappings": [ { "localRoot": "${workspaceRoot}", "remoteRoot": "[your docker project remote root path]" } ], "django": true } ] }

※When request change from attach to launch, you may not success remote debug.

Dockerfile(Django)

Install python library called ptvsd. It has been developed by Microsoft company, but github’s star is few…

RUN pip install ptvsd

Enter fullscreen mode Exit fullscreen mode

my sample Dockerfile

start project

$ docker-compose up -d

Enter fullscreen mode Exit fullscreen mode

enable ptvsd

Edit manage.py

# add import ptvsd
...
# add, port=3000 ptvsd.enable_attach(address=('0.0.0.0', 3000))

Enter fullscreen mode Exit fullscreen mode

my sample manage.py(remove comment out L23)

Attention! Docker container can’t seem to start if you enable ptvsd before start docker container.

start debug

Enter fn + F5(Mac OS). Under bar color changes from blue to orange.

check break point

Attention! Break point can’t seem to use some of other files(etc. polls/url.py, manage.py …). Sorry, I don’t know the reason.

access URL

Access your project url(etc. http://127.0.0.1:8000/polls/), and program will stop break point.

stop break point
