biomaj-download 3.0.24

BioMAJ download service

# About

Microservice to manage the downloads of biomaj.

A protobuf interface is available in biomaj_download/message/message_pb2.py to exchange messages between BioMAJ and the download service.
Messages go through RabbitMQ (to be installed).

# Protobuf

To compile protobuf, in biomaj_download/message:

protoc --python_out=. message.proto

# Development

flake8 biomaj_download/\*.py biomaj_download/download


# Run

## Message consumer:

export BIOMAJ_CONFIG=path_to_config.yml
python bin/biomaj_download_consumer.py

## Web server

If package is installed via pip, you need a file named *gunicorn_conf.py* containing somehwhere on local server:

def worker_exit(server, worker):
from prometheus_client import multiprocess
multiprocess.mark_process_dead(worker.pid)

If you cloned the repository and installed it via python setup.py install, just refer to the *gunicorn_conf.py* in the cloned repository.


export BIOMAJ_CONFIG=path_to_config.yml
rm -rf ..path_to/prometheus-multiproc
mkdir -p ..path_to/prometheus-multiproc
export prometheus_multiproc_dir=..path_to/prometheus-multiproc
gunicorn -c gunicorn_conf.py biomaj_download.biomaj_download_web:app

Web processes should be behind a proxy/load balancer, API base url /api/download

Prometheus endpoint metrics are exposed via /metrics on web server
