Familiar Tools in Unknown Territory: GenAI with SpringAI & Testcontainers
summary
Shows how to build a GenAI JVM app using SpringAI for LLM wiring, PostgreSQL + PGVector as a vector store for RAG, and Testcontainers to spin up Postgres, an MCP scheduling server, and a Docker Model Runner instance for local models. Demo wires embeddings into a vector DB, registers an MCP tool, and verifies a 3‑day hardcoded appointment; issues include model context window limits causing repeated tool calls and GPU/virtualization quirks on Apple Silicon.
