# Build MegaService of Document Summarization on Gaudi

This document outlines the deployment process for a Document Summarization application utilizing the [GenAIComps](https://github.com/opea-project/GenAIComps.git) microservice pipeline on Intel Gaudi server. The steps include Docker image creation, container deployment via Docker Compose, and service execution to integrate microservices such as `llm`. We will publish the Docker images to Docker Hub soon, which will simplify the deployment process for this service.

## 🚀 Build Docker Images

### 1. Build MicroService Docker Image

First of all, you need to build Docker Images locally and install the python package of it.

```bash
git clone https://github.com/opea-project/GenAIComps.git
cd GenAIComps
```

#### Audio to text Service

The Audio to text Service is another service for converting audio to text. Follow these steps to build and run the service:

```bash
docker build -t opea/dataprep-audio2text:latest --build-arg https_proxy=$https_proxy --build-arg http_proxy=$http_proxy -f comps/dataprep/multimedia2text/audio2text/Dockerfile .
```

#### Video to Audio Service

The Video to Audio Service extracts audio from video files. Follow these steps to build and run the service:

```bash
docker build -t opea/dataprep-video2audio:latest --build-arg https_proxy=$https_proxy --build-arg http_proxy=$http_proxy -f comps/dataprep/multimedia2text/video2audio/Dockerfile .
```

#### Multimedia to Text Service

The Multimedia to Text Service transforms multimedia data to text data. Follow these steps to build and run the service:

```bash
docker build -t opea/dataprep-multimedia2text:latest --build-arg https_proxy=$https_proxy --build-arg http_proxy=$http_proxy -f comps/dataprep/multimedia2text/Dockerfile .
```

### 2. Build MegaService Docker Image

To construct the Mega Service, we utilize the [GenAIComps](https://github.com/opea-project/GenAIComps.git) microservice pipeline within the `docsum.py` Python script. Build the MegaService Docker image via below command:

```bash
git clone https://github.com/opea-project/GenAIExamples
cd GenAIExamples/DocSum/
docker build -t opea/docsum:latest --build-arg https_proxy=$https_proxy --build-arg http_proxy=$http_proxy -f Dockerfile .
```

### 3. Build UI Docker Image

Several UI options are provided. If you need to work with multimedia documents, .doc, or .pdf files, suggested to use Gradio UI.

#### Svelte UI

Build the frontend Docker image via below command:

```bash
cd GenAIExamples/DocSum/ui
docker build -t opea/docsum-ui:latest --build-arg https_proxy=$https_proxy --build-arg http_proxy=$http_proxy -f docker/Dockerfile .
```

#### Gradio UI

Build the Gradio UI frontend Docker image using the following command:

```bash
cd GenAIExamples/DocSum/ui
docker build -t opea/docsum-gradio-ui:latest --build-arg https_proxy=$https_proxy --build-arg http_proxy=$http_proxy -f docker/Dockerfile.gradio .
```

#### React UI

Build the frontend Docker image via below command:

```bash
cd GenAIExamples/DocSum/ui
export BACKEND_SERVICE_ENDPOINT="http://${host_ip}:8888/v1/docsum"
docker build -t opea/docsum-react-ui:latest --build-arg BACKEND_SERVICE_ENDPOINT=$BACKEND_SERVICE_ENDPOINT -f ./docker/Dockerfile.react .

docker build -t opea/docsum-react-ui:latest --build-arg BACKEND_SERVICE_ENDPOINT=$BACKEND_SERVICE_ENDPOINT --build-arg https_proxy=$https_proxy --build-arg http_proxy=$http_proxy  -f ./docker/Dockerfile.react .
```

## 🚀 Start Microservices and MegaService

### Required Models

Default model is "Intel/neural-chat-7b-v3-3". Change "LLM_MODEL_ID" environment variable in commands below if you want to use another model.

```bash
export LLM_MODEL_ID="Intel/neural-chat-7b-v3-3"
```

When using gated models, you also need to provide [HuggingFace token](https://huggingface.co/docs/hub/security-tokens) to "HUGGINGFACEHUB_API_TOKEN" environment variable.

### Setup Environment Variable

To set up environment variables for deploying Document Summarization services, follow these steps:

1. Set the required environment variables:

   ```bash
   # Example: host_ip="192.168.1.1"
   export host_ip="External_Public_IP"
   # Example: no_proxy="localhost, 127.0.0.1, 192.168.1.1"
   export no_proxy="Your_No_Proxy"
   export HUGGINGFACEHUB_API_TOKEN="Your_Huggingface_API_Token"
   ```

2. If you are in a proxy environment, also set the proxy-related environment variables:

   ```bash
   export http_proxy="Your_HTTP_Proxy"
   export https_proxy="Your_HTTPs_Proxy"
   ```

3. Set up other environment variables:

   ```bash
   source GenAIExamples/DocSum/docker_compose/set_env.sh
   ```

### Start Microservice Docker Containers

```bash
cd GenAIExamples/DocSum/docker_compose/intel/hpu/gaudi
docker compose -f compose.yaml up -d
```

You will have the following Docker Images:

1. `opea/docsum-ui:latest`
2. `opea/docsum:latest`
3. `opea/llm-docsum-tgi:latest`
4. `opea/whisper:latest`
5. `opea/dataprep-audio2text:latest`
6. `opea/dataprep-multimedia2text:latest`
7. `opea/dataprep-video2audio:latest`

  container_name: docsum-gaudi-react-ui-server
  depends_on:
    - docsum-gaudi-backend-server
  ports:
    - "5174:80"
  environment:
    - no_proxy=${no_proxy}
    - https_proxy=${https_proxy}
