Question

version: '3'
  
services:

  djangoapp:
    build: .
    ports:
      - 80:80
    depends_on:
      - mysql-security
    environment:
      MYSQL_SECURITY_ENV_HOST: mysql-security
      MYSQL_SECURITY_ENV_MYSQL_DATABASE: demo
      MYSQL_SECURITY_PORT_3306_TCP_PORT: 3306
      MYSQL_SECURITY_ENV_MYSQL_ROOT_PASSWORD: root
    networks:
      - my-bridge

  mysql-security:
    image: mysql:5.7
    environment:
      MYSQL_ROOT_PASSWORD: root
      MYSQL_DATABASE: demo
    volumes:
      - mysql-security:/var/lib/mysql
    networks:
      - my-bridge

volumes:
  mysql-security:

networks:
  my-bridge:
    driver: bridge

老师我的docker-compose.yml文件如上。
在docker-compose build成功之后，运行docker-compose up报错：

wuhaodeMacBook-Pro:demo275 wuhao$ docker-compose up
demo275_mysql-security_1 is up-to-date
Creating demo275_djangoapp_1 ... error

ERROR: for demo275_djangoapp_1  Cannot create container for service djangoapp: No command specified

ERROR: for djangoapp  Cannot create container for service djangoapp: No command specified
ERROR: Encountered errors while bringing up the project.

No command specified， 不知道是指哪个命令没指定？
再就是，像这种docker-compose up报错了，我们应该怎么debug呢？
不知道问题去哪里找。

您这个djangoapp的DockerFile是自己写的么？在哪里呢，是不是写的有问题
