Debugging a Python Flask app in Docker Compose

This is the companion repository to this blog post (Medium)

Running the application

$ docker-compose run --build -d

Debugging the application

If changes were made to the file (e.g. added breakpoint), build first...

$ docker-compose build

Run the application in Docker Compose but specify a particular command...

$ docker-compose run -p 8000:8000 svc1 python3 -m pdb app.py

Debug the application as you would any other Python application

Interacting with the application

Display simple message

$ curl localhost:8000

Add message to application (Redis cache)

$ curl -X POST localhost:8000/message/<message_to_add>

Get message from application (stored in Redis)

$ curl -X POST localhost:8000/message
