RESPONSE_AS_FILE == True

Creates a respone file on the request storage, named dossier_Id / file_Id + RESPONSE_FILE_EXTENSION with the ANALYSIS_DATA as content.

Development

Local Setup

You can run the infrastructure either as module via. src/serve.py or as Dockercontainer simulating the kubernetes environment

Install module / build docker image

pip install -e .
pip install -r requirements.txt

docker build -f Dockerfile -t pyinfra .

Run rabbitmq & minio
```
docker-compose up
```

Run module / docker container

python src/serve.py

docker run --net=host pyinfra
