Question

我正在使用 Djnago 和 MySql 构建一个应用程序。我想使用 docker 来部署我的应用程序。我准备了一个requirement.txt、docker-compose.yml和一个Dockerfile docker-compose.yml

version: '3'
services:
    db:
        image: mariadb
        restart: always
        ports:
            - 3306:3306
        environment:
                MYSQL_DATABASE: stage_emsi
                MYSQL_USER: root
                MYSQL_PASSWORD: password
                MYSQL_ROOT_PASSWORD: password
    web:
        build: .
        command:  python manage.py runserver 0.0.0.0:8000
        ports: 
            - "8000:8000"
        volumes:
            - .:/code
        depends_on: 
            - db
        image: web:django

Dockerfile

FROM python:3
ENV PYTHONUNBUFFERED=1
RUN mkdir /code
WORKDIR /code
RUN pip install mysqlclient
COPY requirements.txt /code/
RUN pip install -r requirements.txt
COPY . /code/

错误

Answer 1

检查您的 Django 应用程序数据库连接设置。您似乎正在尝试通过本地 Linux 套接字文件而不是 MySQL 数据库的 IP 地址进行连接。
