biomaj-download 3.0.20

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
