TerraForm stack for deploying ChatQnA using Vertex AI Vector Search

[arun-gupta]

ChatQnA is one of the GenAI examples. It is a chatbot for question and answer through retrieval augmented generation (RAG). All details about the sample are available at https://github.com/opea-project/GenAIExamples/tree/main/ChatQnA.

This example uses Postgres database with pgvector plug-in as a microservice. There is a need to show how Vertex AI Vector Search can be used instead of the built-in database. Any of the deployment mechanisms (Docker Compose, GKE, or Cloud Run) can be used.

This is a specific issue for Google Cloud for the mega issue at https://github.com/opea-project/GenAIExamples/issues/427.
