The sample application supports both [Ollama](https://ollama.ai/). This guide provides instructions for the following scenarios:

- Run Ollama in a container
- Run Ollama outside of a container

While all platforms can use any of the previous scenarios, the performance and
GPU support may vary. You can use the following guidelines to help you choose the appropriate option:

- Run Ollama in a container if you're on Linux, and using a native installation of the Docker Engine, or Windows 10/11, and using Docker Desktop, you
  have a CUDA-supported GPU, and your system has at least 8 GB of RAM.
- Run Ollama outside of a container if running Docker Desktop on a Linux Machine.

Choose one of the following options for your LLM service.

{{< tabs >}}
{{< tab name="Run Ollama in a container" >}}

When running Ollama in a container, you should have a CUDA-supported GPU. While you can run Ollama in a container without a supported GPU, the performance may not be acceptable. Only Linux and Windows 11 support GPU access to containers.

To run Ollama in a container and provide GPU access:

1. Install the prerequisites.
   - For Docker Engine on Linux, install the [NVIDIA Container Toolkilt](https://github.com/NVIDIA/nvidia-container-toolkit).
   - For Docker Desktop on Windows 10/11, install the latest [NVIDIA driver](https://www.nvidia.com/Download/index.aspx) and make sure you are using the [WSL2 backend](/manuals/desktop/features/wsl/_index.md#turn-on-docker-desktop-wsl-2)
2. The `docker-compose.yaml` file already contains the necessary instructions. In your own apps, you'll need to add the Ollama service in your `docker-compose.yaml`. The following is
   the updated `docker-compose.yaml`:

   ```yaml
   ollama:
     image: ollama/ollama
     container_name: ollama
     ports:
       - "8000:8000"
     deploy:
       resources:
         reservations:
           devices:
             - driver: nvidia
               count: 1
               capabilities: [gpu]
   ```

   > [!NOTE]
   > For more details about the Compose instructions, see [Turn on GPU access with Docker Compose](/manuals/compose/how-tos/gpu-support.md).

3. Once the Ollama container is up and running it is possible to use the `download_model.sh` inside the `tools` folder with this command:

   ```console
   . ./download_model.sh <model-name>
   ```

Pulling an Ollama model can take several minutes.

{{< /tab >}}
{{< tab name="Run Ollama outside of a container" >}}

To run Ollama outside of a container:

1. [Install](https://github.com/jmorganca/ollama) and run Ollama on your host
   machine.
2. Pull the model to Ollama using the following command.

   ```console
   $ ollama pull llama2
   ```

3. Remove the `ollama` service from the `docker-compose.yaml` and update properly the connection variables in `winy` service:

   ```diff
   - OLLAMA=http://ollama:11434
   + OLLAMA=<your-url>
   ```

{{< /tab >}}
{{< /tabs >}}

## Run your RAG application

At this point, you have the following services in your Compose file:

- Server service for your main RAG application
- Database service to store vectors in a Qdrant database
- (optional) Ollama service to run the LLM
  service

Once the application is running, open a browser and access the application at [http://localhost:8501](http://localhost:8501).

Depending on your system and the LLM service that you chose, it may take several
minutes to answer.

## Summary

In this section, you learned how to set up a development environment to provide
access all the services that your GenAI application needs.
