debugging-dockerized-python-app's Introduction

What?

This is example project for my blog entry: Debugging Dockerized Python (Django) App With PyCharm

Usage

Run helper script ./build-core-django.sh. It will build core image.
Run docker compose command: docker-compose -f docker-compose-development.yml up. It will build development image, and then run it with Postgres container.
Check if everything is ok: docker ps. There should be 2 containers running: debuggingdockerizedpythonapp_django_1 and debuggingdockerizedpythonapp_postgres_1. Note that the firs one is forwarding two ports: 2000 for SSH connection and 8080 for webserver.
In PyCharm, add new python interpreter. Choose remote and fill it's configuration with settings:

Host: your host ip address (for my docker-mashine: 192.168.99.100)
Port: 2000
Username: root
Password: password
Interpreter path: /usr/local/bin/python

For the first time it may complain about new host and so on. So don't worry.
Add new run configuration with settings:

Host: 0.0.0.0
Port: 8080
Environment variables: DJANGO_SETTINGS_MODULE=myapp.settings
Working directory: /app
Path mappings: your absolute path to project direcory=/app

Hit run button! You should get fresh running Django app.
Now set breakpoint in setting file and start debug.
Voilà!

[Question]

I really really liked your approached using ssh for debugging / running tests in pycharm.
I followed this approach but yet I did not figure out how to configure manage.py to the docker container in Pycharm.
In my setup I made a proxy .sh script for that purpose.
Do you have any idea how this could work in pycharm?

Thanks a lot
