This example deploys a basic RAG pipeline for chat Q&A and serves inferencing from an NVIDIA API Catalog endpoint. You do not need a GPU on your machine to run this example.

Complete the common prerequisites.

1. Export your NVIDIA API key as an environment variable:

   export NVIDIA_API_KEY="nvapi-<...>"
   

2. Start the containers:

   cd RAG/examples/basic_rag/langchain/
   docker compose up -d --build

   Example Output

    ✔ Network nvidia-rag           Created
    ✔ Container rag-playground     Started
    ✔ Container milvus-minio       Started
    ✔ Container chain-server       Started
    ✔ Container milvus-etcd        Started
    ✔ Container milvus-standalone  Started
   

3. Confirm the containers are running:

   docker ps --format "table {{.ID}}\t{{.Names}}\t{{.Status}}"

   Example Output

   CONTAINER ID   NAMES               STATUS
   39a8524829da   rag-playground      Up 2 minutes
   bfbd0193dbd2   chain-server        Up 2 minutes
   ec02ff3cc58b   milvus-standalone   Up 3 minutes
   6969cf5b4342   milvus-minio        Up 3 minutes (healthy)
   57a068d62fbb   milvus-etcd         Up 3 minutes (healthy)
   

4. Open a web browser and access http://localhost:8090 to use the RAG Playground.
