我正在使用docker-compose来部署多容器python Flask Web应用程序.我在构建期间难以理解如何在postgresql数据库中创建表,所以我不必用psql手动添加它们.

我的docker-compose.yml文件是:

web:
  restart: always
  build: ./web
  expose:
    - "8000"
  links:
    - postgres:postgres
  volumes:
    - /usr/src/flask-app/static
  env_file: .env
  command: /usr/local/bin/gunicorn -w 2 -b :8000 app:app

nginx:
  restart: always
  build: ./nginx/
  ports:
    - "80:80"
  volumes:
    - /www/static
  volumes_from:
    - web
  links:
    - web:web

data:
  restart: always
  image: postgres:latest
  volumes:
    - /var/lib/postgresql
  command: "true"

postgres:
  restart: always
  image: postgres:latest
  volumes_from:
    - data
  ports:
    - "5432:5432"

我不想输入psql才能输入:

CREATE DATABASE my_database;
CREATE USER this_user WITH PASSWORD 'password';
GRANT ALL PRIVILEGES ON DATABASE …
