Dockerise django应用程序用于生产,无法解决:process“/bin/sh-c pip install

dockerfile docker-compose docker django

mightycode Newton · 技术社区 · 2 年前

我试着把一个django集装箱装进码头进行生产。

所以我有我的档案:

FROM python:3.8-alpine

ENV PATH="/scripts:${PATH}"

COPY ./requirements.txt /requirements.txt
RUN apk add --update --no-cache --virtual .tmp gcc libc-dev linux-headers
RUN pip install -r /requirements.txt
RUN apk del .tmp

RUN mkdir /app
COPY ./Welzijn /app
WORKDIR /app
COPY ./scripts /scripts

RUN chmod +x /scripts/*

RUN mkdir -p /vol/web/media
RUN mkdir -p /vol/web/static
RUN adduser -D user
RUN chown -R user:user /vol
RUN chmod -R 755 /vol/web
USER user

CMD ["entrypoint.sh"]

以及docker compose文件:

version: "3.9"

services:
  app:
    build:
      context: .
    ports:
      - "8000:8000"
    volumes:
      - ./Welzijn:/app
    command: >
      sh -c "python ./manage.py migrate &&      
             python ./manage.py runserver 0:8000"
    environment:
      - DEBUG=1
    env_file:
      - ./.env

和requirements.txt文件:

Django>=4.0.4
uWSGI>=2.0.18,<2.1
djangorestframework>=3.13.1
psycopg2>=2.9.3
drf-spectacular>=0.22.1
Pillow>=9.1.0
drf-yasg==1.20.0 
django-cors-headers==3.10.1
django-dotenv

但是当我执行docker compose-up-build时

我收到以下错误:

3.686       'psycopg2-binary' package instead.

以下是使用Postgres数据库和PgAdmin将django码头化以用于生产的完整流程。
