Best way to structure directory/docker files

Hi. I’m setting up a Django project and I’m trying to figure out the best way to structure it having just a local and a prod environment. Is it best practice to use Docker for local dev? ​and if so what’s the cleanest way to structure the Dockerfile and project? And in general what are some good places to deploy everything and postgres database to prod?

Not a vibe coder, just very used to Firebase/supabase and Baas and wanted to scale up a bit
