# Postgres with pgvector + RAG Agent app (from repo git@git.lesha.spb.ru:alex/RagAgent.git).
# Clone the repo, then: docker compose up -d
# App and DB share network "rag_net"; app uses RAG_DB_DSN with host=postgres.
# DB init: scripts in docker/postgres-init/ run on first start (empty volume); to disable, comment out the init volume.
