Simple microservice which goes alongside the stac-generator to write the generated STAC items to a STAC API.
The microservice consumes a Redis list items published by the stac-generator and writes them to a STAC API.
| Name | Description |
|---|---|
| REDIS_HOST | Redis host |
| REDIS_PORT | Redis port |
| REDIS_INPUT_LIST_NAME | Redis input list name |
| REDIS_OUTPUT_LIST_NAME | Redis output list name |
| STAC_FASTAPI_READ_HOST | STAC API host for checking if the STAC Items are already present |
| STAC_FASTAPI_WRITE_HOST | STAC API host for writing the STAC Items |
| NUM_RETRIES | Number of retries for writing to STAC-FastAPI |
Input paylaod is standard compliant stac, accompanied with the collection id where the item needs to be written to.
