And there are many other images for different things like databases, for example for:

* [PostgreSQL](https://hub.docker.com/_/postgres)
* [MySQL](https://hub.docker.com/_/mysql)
* [MongoDB](https://hub.docker.com/_/mongo)
* [Redis](https://hub.docker.com/_/redis), etc.

예를 들어, 공식 [Python Image](https://hub.docker.com/_/python)가 있습니다.

그리고 데이터베이스 등 다양한 용도의 다른 이미지도 많이 있습니다. 예를 들면:

* [PostgreSQL](https://hub.docker.com/_/postgres)
* [MySQL](https://hub.docker.com/_/mysql)
* [MongoDB](https://hub.docker.com/_/mongo)
* [Redis](https://hub.docker.com/_/redis) 등

As SQLModel is based on SQLAlchemy, you can easily use **any database supported** by SQLAlchemy (which makes them also supported by SQLModel), like:

* PostgreSQL
* MySQL
* SQLite
* Oracle
* Microsoft SQL Server, etc.

In this example, we'll use **SQLite**, because it uses a single file and Python has integrated support. So, you can copy this example and run it as is.

notify_nats           publish bucket notifications to NATS endpoints
notify_nsq            publish bucket notifications to NSQ endpoints
notify_mysql          publish bucket notifications to MySQL databases
notify_postgres       publish bucket notifications to Postgres databases
notify_elasticsearch  publish bucket notifications to Elasticsearch endpoints
notify_redis          publish bucket notifications to Redis datastores

也有一個公開的 [Docker Hub](https://hub.docker.com/)，內含許多工具、環境、資料庫與應用的預先製作「官方映像」。

例如，有官方的 [Python 映像](https://hub.docker.com/_/python)。

也有許多其他針對不同用途的映像，例如資料庫：

* [PostgreSQL](https://hub.docker.com/_/postgres)
* [MySQL](https://hub.docker.com/_/mysql)
* [MongoDB](https://hub.docker.com/_/mongo)
* [Redis](https://hub.docker.com/_/redis) 等。

使用預製的容器映像很容易「組合」並使用不同工具。例如，嘗試一個新資料庫。多數情況下，你可以使用官方映像，並僅用環境變數加以設定。

如此，你可以學會關於容器與 Docker 的知識，並將這些知識重複運用到許多不同工具與元件上。
