Overview

This is a quick development environment to experiment with Langfuse and LangChain.

It's a small, minimal test API for generating RAG recipes with flavor pairings from one of my favorite cookbooks.

Server Installation

docker build -t fastapi-pgvector-app .
docker run - 80:80 fastapi-pgvector-app //see note on env below

Docker Network

You may need to setup a docker network, I had to on Windows but not on Mac?
