Gunicorn: тайм-аут рабочего и выход рабочего во всех контейнерах ⇐ Python

[Anonymous]

Небольшая предыстория моей проблемы:

У меня есть следующий файл конфигурации Gunicorn:

Код: Выделить всё

gunicorn_cofig.py

Код: Выделить всё

pidfile = 'app.pid'
worker_tmp_dir = '/dev/shm'
worker_class = 'gthread'
workers = 1
worker_connections = 1000
timeout = 30
keepalive = 1
threads = 2
proc_name = 'app'
bind = '0.0.0.0:8080'
backlog = 2048
accesslog = '-'
errorlog = '-'

Initially, I was running a single Flask app and Nginx in Docker and Gunicorn never had an issue. Later I added another app and configured my Nginx to redirect requests from different subdomain to different port (ex. mydomain.com -> port 81 and app.mydomain.com -> port 5000) (If I understand correctly since I bind all subdomains to the same IP (I use LetsEncrypt) request from all subdomains come to port 443 then Nginx reverse proxies them to respective ports). For that I just copy pasted the same

Код: Выделить всё

gunicorn_cofig.py

in the new app and it was working fine.
Now I added 6 apps and I am using the same config file in all of them and I am getting the following error:

and so on, for every app.
I tried to change

Код: Выделить всё

proc_name = 'app'

to different values but the same thing is happening. Here's a snippet of my docker compose file where I run the command for Gunicorn:

Код: Выделить всё

m:
build:
dockerfile: ./m/Dockerfile
context: ../../
command: gunicorn --bind 0.0.0.0:82 --workers 3 ${M_FLASK_APP}:app
environment:
- FLASK_ENV=${FLASK_ENV}
- PYTHONUNBUFFERED=1
ports:
- 82:82
volumes:
- ./m/src:/opt/m

p:
build:
dockerfile: ./p/Dockerfile
context: ../../
command: gunicorn --bind 0.0.0.0:83 --workers 3 ${P_FLASK_APP}:app
environment:
- FLASK_ENV=${FLASK_ENV}
- PYTHONUNBUFFERED=1
ports:
- 83:83
volumes:
- ./p/src:/opt/p

Can somebody guide me to the right direction. Is it gunicorn configuration problem or docker (since I am running six apps and 1 nginx server)?
