This is used to send requests for caption classification. You must specify only ONE of an http or gRPC endpoint. If both are specified gRPC will take precedence. |
| `CAPTION_CLASSIFIER_MODEL_NAME`  | - `deberta_large` <br/>                                    | The name of the caption classifier model. |
| `DOUGHNUT_TRITON_HOST`           | - `triton-doughnut` <br/>                                  | The hostname or IP address of the DOUGHNUT model service. |
| `DOUGHNUT_TRITON_PORT`           | - `8001` <br/>                                             | The port number on which the DOUGHNUT model service is listening. |
| `INGEST_LOG_LEVEL`               | - `DEBUG` <br/> - `INFO` <br/> - `WARNING` <br/> - `ERROR` <br/> - `CRITICAL` <br/> | The log level for the ingest service, which controls the verbosity of the logging output. |

| `NIM_NGC_API_KEY`                | —                                                          | The key that NIM microservices inside docker containers use to access NGC resources. This is necessary only in some cases when it is different from `NGC_API_KEY`. If this is not specified, `NGC_API_KEY` is used to access NGC resources. |
| `NVIDIA_BUILD_API_KEY`           | —                                                          | The key to access NIMs that are hosted on build.nvidia.com instead of a self-hosted NIM.
