Question

根据these docs，我可以使用env var POSTGRES_DB指定postgres docker镜像创建的数据库的名称。我已经在我的docker-compose文件中设置了它，但它没有被创建。

以下是撰写文件中的相关部分：

pg:
    image: postgres:10
    volumes:
      - db-data:/var/lib/postgresql/data
    environment:
      POSTGRES_DB: user-auth
      POSTGRES_USER: postgres
      POSTGRES_PASSWORD: postgres

以下是日志：

Answer 1

您很可能在未设置env变量的情况下启动了容器。然后，在没有用户或数据库信息的情况下初始化数据库。

您需要删除该卷，然后重试。

Answer 2

我在 Visual Studio Code 中使用 devcontainer（Python 3 和 PostgreSQL），sqltools.connections 中的 devcontainer.json 设置覆盖了 docker-compose.yml 中的配置。我也在那里更改了设置，它按预期工作！

Postgres图像不是创建数据库
