我在docker容器中设置了一个django项目,并且每个东西都按预期工作,除了我在mysql映像中找不到项目数据库.

Dockerfile

FROM python:3

RUN mkdir /django-website
WORKDIR /django-website
COPY . /django-website
RUN pip install -r requirements.txt

泊坞窗,compose.yml

version: '3'

services:
    db:
        image: mysql:5.7
        restart: always
        environment:
            - MYSQL_ROOT_PASSWORD=root
            - MYSQL_DATABASE=mywebsite
            - MYSQL_USER=root
            - MYSQL_PASSWORD=root
        ports:
            - '33060:3306'
        volumes:
            - /var/lib/mysql
    web:
        build: .
        command: python manage.py runserver 0.0.0.0:8000
        volumes:
            - .:/django-website
        ports:
            - '8000:8000'
        links:
            - db

settings.py

DATABASES = {
    'default': {
        'ENGINE': "django.db.backends.mysql",
        'NAME': "mywebsite",
        'USER': "root",
        'PASSWORD': "root",
        'HOST': 'db',
        'PORT': '3306',
    }
}
