## Build MegaService Docker Image

To construct the Megaservice of ArbPostHearingAssistant, the [GenAIExamples](https://github.com/opea-project/GenAIExamples.git) repository is utilized. Build MegaService Docker image via command below:

```bash
git clone https://github.com/opea-project/GenAIExamples.git
cd GenAIExamples/ArbPostHearingAssistant
docker build --no-cache -t opea/arb-post-hearing-assistant:latest --build-arg https_proxy=$https_proxy --build-arg http_proxy=$http_proxy -f Dockerfile .
```

## Build UI Docker Image

Build frontend Docker image via below command:

```bash
cd GenAIExamples/ArbPostHearingAssistant/ui
docker build -t opea/arb-post-hearing-assistant-gradio-ui:latest --build-arg https_proxy=$https_proxy --build-arg http_proxy=$http_proxy -f ./docker/Dockerfile .
```

## Generate a HuggingFace Access Token

Some HuggingFace resources, such as certain models, are only accessible if the developer has an access token. If you don't have a HuggingFace access token, you can create one by registering at [HuggingFace](https://huggingface.co/) and following [these steps](https://huggingface.co/docs/transformers.js/en/guides/private#step-1-generating-a-user-access-token).

## Troubleshooting

1. If you get errors like "Access Denied", [validate micro service](./README.md#validate-microservices) first. A simple example:

   ```bash
   http_proxy=""
   curl http://${host_ip}:8008/generate \
     -X POST \
     -d '{"inputs":"    ### System: Please translate the following Golang codes into  Python codes.    ### Original codes:    '\'''\'''\''Golang    \npackage main\n\nimport \"fmt\"\nfunc main() {\n    fmt.Println(\"Hello, World!\");\n    '\'''\'''\''    ### Translated codes:","parameters":{"max_tokens":17, "do_sample": true}}' \
     -H 'Content-Type: application/json'
   ```

2. (Docker only) If all microservices work well, check the port ${host_ip}:7777, the port may be allocated by other users, you can modify the `compose.yaml`.
3. (Docker only) If you get errors like "The container name is in use", change container name in `compose.yaml`.
