singhsanket143/Containerised-Microservices-Node-And-Python — reverse-engineered prompt

Build me a simple containerized flight booking demo with separate services for an API Gateway, a Flights service, a Flight Booking service, and a small Python service.

I want someone to be able to run it locally with one command, then use the gateway to see available flights and create a basic booking for a selected flight. Keep the data simple, in memory or a lightweight local setup is fine. The main point is to show how the services talk to each other cleanly, not to build a full airline system.

Please make the endpoints easy to test, return clear JSON, and include basic error messages when a flight or booking request is invalid. Add a short README with how to start everything, what each service does, and example requests I can copy and paste.

Keep it beginner friendly and avoid adding login, payments, or anything complicated unless it’s really necessary. Look up current docs online if you need to.
