## SearchQnA Quick Start Deployment

This section describes how to quickly deploy and test the SearchQnA service manually on an AMD ROCm Platform. The basic steps are:

1. [Access the Code](#access-the-code)
2. [Configure the Deployment Environment](#configure-the-deployment-environment)
3. [Deploy the Services Using Docker Compose](#deploy-the-services-using-docker-compose)
4. [Check the Deployment Status](#check-the-deployment-status)
5. [Validate the Pipeline](#validate-the-pipeline)
6. [Cleanup the Deployment](#cleanup-the-deployment)

### Access the Code

Clone the GenAIExample repository and access the SearchQnA AMD ROCm Platform Docker Compose files and supporting scripts:

```bash
git clone https://github.com/opea-project/GenAIExamples.git
cd GenAIExamples/SearchQnA/docker_compose/amd/gpu/rocm
```

Checkout a released version, such as v1.2:

```bash
git checkout v1.2
```

### Generate a HuggingFace Access Token

Some HuggingFace resources require an access token. Developers can create one by first signing up on [HuggingFace](https://huggingface.co/) and then generating a [user access token](https://huggingface.co/docs/transformers.js/en/guides/private#step-1-generating-a-user-access-token).

### Configure the Deployment Environment

To set up environment variables for deploying SearchQnA services, set up some parameters specific to the deployment environment and source the `set_env.sh` script in this directory:

#### For vLLM inference type deployment (default)

```bash
export host_ip="External_Public_IP"           # ip address of the node
export GOOGLE_CSE_ID="your cse id"
export GOOGLE_API_KEY="your google api key"
export HUGGINGFACEHUB_API_TOKEN="Your_HuggingFace_API_Token"
export http_proxy="Your_HTTP_Proxy"           # http proxy if any
export https_proxy="Your_HTTPs_Proxy"         # https proxy if any
export no_proxy=localhost,127.0.0.1,$host_ip  # additional no proxies if needed
export NGINX_PORT=${your_nginx_port}          # your usable port for nginx, 80 for example
source ./set_env_vllm.sh
```

#### For TGI inference type deployment

```bash
export host_ip="External_Public_IP"           # ip address of the node
export GOOGLE_CSE_ID="your cse id"
export GOOGLE_API_KEY="your google api key"
export HUGGINGFACEHUB_API_TOKEN="Your_HuggingFace_API_Token"
export http_proxy="Your_HTTP_Proxy"           # http proxy if any
export https_proxy="Your_HTTPs_Proxy"         # https proxy if any
export no_proxy=localhost,127.0.0.1,$host_ip  # additional no proxies if needed
export NGINX_PORT=${your_nginx_port}          # your usable port for nginx, 80 for example
source ./set_env.sh
```

Consult the section on [SearchQnA Service configuration](#SearchQnA-configuration) for information on how service specific configuration parameters affect deployments.

### Deploy the Services Using Docker Compose

To deploy the SearchQnA services, execute the `docker compose up` command with the appropriate arguments. For a default deployment, execute:

#### For vLLM inference type deployment (default)

```bash
//with VLLM:
docker compose -f compose_vllm.yaml up -d
```

#### For TGI inference type deployment

```bash
//with TGI:
docker compose -f compose.yaml up -d
```

**Note**: developers should build docker image from source when:

- Developing off the git main branch (as the container's ports in the repo may be different from the published docker image).
- Unable to download the docker image.
- Use a specific version of Docker image.

Please refer to the table below to build different microservices from source:

### Check the Deployment Status

After running Docker Compose, the list of images can be checked using the following command:

```
docker ps -a
```

For the default deployment, the following containers should have started

#### For vLLM inference type deployment (default)

```

If any issues are encountered during deployment, refer to the [Troubleshooting](../../../../README_miscellaneous.md#troubleshooting) section.

### Validate the Pipeline

Once the SearchQnA services are running, test the pipeline using the following command:

```bash
    DATA='{"messages": "What is the latest news from the AI world? '\
    'Give me a summary.","stream": "True"}'

    curl http://${host_ip}:3008/v1/searchqna \
    -H "Content-Type: application/json" \
    -d "$DATA"
```

**Note** The value of _host_ip_ was set using the _set_env.sh_ script and can be found in the _.env_ file.

Checking the response from the service. The response should be similar to JSON:

```textmate

data: [DONE]
```

A response text similar to the one above indicates that the service verification was successful.

**Note** : Access the SearchQnA UI by web browser through this URL: `http://${host_ip}:80`. Please confirm the `80` port is opened in the firewall. To validate each microservice used in the pipeline refer to the [Validate Microservices](#validate-microservices) section.

### Cleanup the Deployment

To stop the containers associated with the deployment, execute the following command:

#### For vLLM inference type deployment (default)

```bash
//with VLLM:
docker compose -f compose_vllm.yaml down
```

#### For TGI inference type deployment

```bash
//with TGI:
docker compose -f compose.yaml down
```

All the SearchQnA containers will be stopped and then removed on completion of the "down" command.

## SearchQnA Docker Compose Files

When deploying a SearchQnA pipeline on an AMD GPUs (ROCm), different large language model serving frameworks can be selected. The table below outlines the available configurations included in the application. These configurations can serve as templates and be extended to other components available in [GenAIComps](https://github.com/opea-project/GenAIComps.git).

| File                                     | Description                                                                                |
| ---------------------------------------- | ------------------------------------------------------------------------------------------ |
| [compose.yaml](./compose.yaml)           | Default compose file using tgi as serving framework                                        |
| [compose_vllm.yaml](./compose_vllm.yaml) | The LLM serving framework is vLLM. All other configurations remain the same as the default |

    -X POST \
    -d '{"inputs":"What is Deep Learning?","parameters":{"max_new_tokens":17, "do_sample": true}}' \
    -H 'Content-Type: application/json'
```

7. LLM Microservice

   ```bash
    curl http://${host_ip}:3007/v1/chat/completions\
      -X POST \
      -d '{"query":"What is Deep Learning?","max_tokens":17,"top_k":10,"top_p":0.95,"typical_p":0.95,"temperature":0.01,"repetition_penalty":1.03,"stream":true}' \

        "messages": "What is the latest news? Give me also the source link.",
        "stream": "true"
        }'
   ```

9. Nginx Service

   ```bash
   curl http://${host_ip}:${NGINX_PORT}/v1/searchqna \
       -H "Content-Type: application/json" \
       -d '{
        "messages": "What is the latest news? Give me also the source link.",
        "stream": "true"
        }'
   ```

## Launch the UI

Access the UI at http://${EXTERNAL_HOST_IP}:${SEARCH_FRONTEND_SERVICE_PORT}. A page should open when navigating to this address.
![UI start page](../../../../assets/img/searchqna-ui-starting-page.png)

The appearance of such a page indicates that the service is operational and responsive, allowing functional UI testing to proceed.

Let's enter the task for the service in the "Enter prompt here" field. For example, "What is DeepLearning?" and press Enter. After that, a page with the result of the task should open:

![UI start page](../../../../assets/img/searchqna-ui-response-example.png)
A correct result displayed on the page indicates that the UI service has been successfully verified.

## Conclusion

This guide should enable developers to deploy the default configuration or any of the other compose yaml files for different configurations. It also highlights the configurable parameters that can be set before deployment.
