Can the number of gunicorn threads be changed easily?

Question

When I run MegaQC using docker-compose on a server with a higher core count (48 cores / 256GB RAM) it attempts to spawn too many gunicorn threads and crashes with a memory error. I have gotten around this by mounting a modified gunicorn_conf.py over top of the existing one in the container. Is there another way to set the number of gunicorn threads?

Hi @eandersonIGS. Currently we're using the tiangolo/meinheld-gunicorn-flask image, which I believe you can configure using environment variables, e.g. https://github.com/tiangolo/meinheld-gunicorn-flask-docker#workers_per_core. You can either provide these variables by editing the compose file, or on the CLI: https://docs.docker.com/compose/environment-variables/set-environment-variables/.
