У меня есть сервер Flask, который я использую на AWS Fargate. Моя задача имеет 2 виртуальных ЦП и 8 ГБ памяти. Мой сервер может отвечать только на один запрос за раз. Если я выполняю 2 запроса API одновременно, каждый из которых занимает 7 секунд, первый запрос вернется через 7 секунд, а второй - 14 секунд.
Это мой файл Docker (используется * 1003). * это репо ):
FROM tiangolo/uwsgi-nginx-flask:python3.7
COPY ./requirements.txt requirements.txt
RUN pip3 install --no-cache-dir -r requirements.txt
RUN python3 -m spacy download en
RUN apt-get update
RUN apt-get install wkhtmltopdf -y
RUN apt-get install poppler-utils -y
RUN apt-get install xvfb -y
COPY ./ /app
У меня есть следующий файл конфигурации:
[uwsgi]
module = main
callable = app
enable-threads = true
Это мои журналы при запуске сервера:
