biomaj-process 3.0.19

# About

[](https://badge.fury.io/py/biomaj-process)

Microservice to manage the process execution of biomaj.

A protobuf interface is available in biomaj_process/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_process/message:

protoc –python_out=. message.proto

# Development

flake8 biomaj_process

CONFIG=tests/config.yml python -m pytest -v tests/biomaj_tests.py

# Run

## Message consumer:

export BIOMAJ_CONFIG=path_to_config.yml python bin/biomaj_process_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 ..path_to/gunicorn_conf.py biomaj_download.biomaj_process_web:app

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

A prometheus /metrics endpoint is exposed on web server

In case of proxy comm failure, sleep a few seconds before retry

3.0.15:

Add proc name in logs for waiting and result

3.0.14:

Add env var BIOMAJ_HOST_DATA_DIR to use with docker process executor to specify data.dir location if different between host and container (if BIOMAJ_DATA_DIR not a subdirectory of BIOMAJ_DIR for example)
