我已经对我现有的使用 MySQL 数据库的 Django Rest 项目进行了 docker 化。
我的码头文件：
FROM python:2.7
ENV PYTHONUNBUFFERED 1
RUN mkdir /code
WORKDIR /code
COPY . /code/
RUN pip install -r requirements.txt
还有我的 docker-compose.yml 文件：
version: '3'
services:
web:
build: .
command: bash -c "python manage.py migrate && python manage.py runserver 0.0.0.0:8000"
volumes:
- .:/code
depends_on:
- db
ports:
- "8000:8000"
db:
image: mysql
environment:
MYSQL_ROOT_PASSWORD: root
MYSQL_DATABASE: libraries
MYSQL_USER: root
MYSQL_PASSWORD: root
我的命令是成功的docker-compose build，docker-compose up后来的输出是：
D:\Development\personal_projects\library_backend>docker-compose up
Starting librarybackend_db_1 ... done
Starting librarybackend_web_1 ... done
Attaching to librarybackend_db_1, librarybackend_web_1

我现在可以通过点击 localhost:8000 来访问我的应用程序。但是，由于它在容器中创建了一个新的数据库实例，我不知道如何在那里创建一个超级用户并登录到我的管理界面。通常没有 docker，我运行python manage.py createsuperuser启动交互式命令提示符的命令以输入管理员用户的凭据。
- 我该如何处理？
- 如果我有一个包含数据的现有数据库，我如何在容器中的这个数据库中使用它（填充表）？
