Я пытаюсь ускорить Django, используя Gunicorn
У меня есть Dockerfile, например:
FROM python:3.6.8-stretch
RUN apt-get update && apt-get install -y --no-install-recommends nginx netcat postgresql-client
COPY requirements.txt /opt/
RUN pip install -r /opt/requirements.txt
RUN mkdir -p /run/nginx
RUN chmod +x /opt/my_turbo_app/deploy/docker/run-scripts/entrypoint.sh
ENTRYPOINT ["/opt/my_turbo_app/deploy/docker/run-scripts/entrypoint.sh"]
An entrypoint.sh как:
exec nginx &
gunicorn wsgi:application --bind 0.0.0.0:8000 --timeout 240 --workers 7 --log-file=- --log-level debug
И requirements.txt с:
gevent==20.5.0
gunicorn==20.0.4
django==2.2.6
djangorestframework==3.10.3
Я создаю Dockerfile без ошибок:
$ docker build -t my-turbo-app:latest
, а затем запускаю его с:
$ docker run --rm -p 6379:6379 -d --name redis redis
$ docker run --rm -p 5432:5432 -d -e POSTGRES_HOST_AUTH_METHOD=trust --name postgres postgres
$ docker exec -it postgres psql -U postgres -h 127.0.0.1 -c 'CREATE DATABASE turbo_db;'
$ docker run -d --name my-turbo-app --link postgres:localhost --link redis:localhost -p 8000:8000 my-turbo-app:latest
Контейнер my-turbo-app раскручивается на секунду, потом вылетает.
Запуск docker logs my-turbo-app показывает:
+ gunicorn wsgi:application --bind 0.0.0.0:8000 --timeout 240 --workers 7 -k gevent --log-file=- --log-level debug
+ exec nginx

Я пытался привязать разные порты, но, похоже, это не сработало. Как заставить Gunincorn работать с docker?
