## Environment Variables

!!! tip
    If you already know what "environment variables" are and how to use them, feel free to skip to the next section below.

* <a href="https://pythonhosted.org/itsdangerous/" target="_blank"><code>itsdangerous</code></a> - `SessionMiddleware` 지원을 위해 필요.
* <a href="https://pyyaml.org/wiki/PyYAMLDocumentation" target="_blank"><code>pyyaml</code></a> - Starlette의 `SchemaGenerator` 지원을 위해 필요 (FastAPI와 쓸때는 필요 없을 것입니다).
* <a href="https://graphene-python.org/" target="_blank"><code>graphene</code></a> - `GraphQLApp` 지원을 위해 필요.

- <a href="https://pythonhosted.org/itsdangerous/" target="_blank"><code>itsdangerous</code></a> - 需要使用 `SessionMiddleware` 支援時安裝。
- <a href="https://pyyaml.org/wiki/PyYAMLDocumentation" target="_blank"><code>pyyaml</code></a> - 用於支援 Starlette 的 `SchemaGenerator` (如果你使用 FastAPI，可能不需要它)。

用於 FastAPI / Starlette：

- <a href="https://www.uvicorn.org" target="_blank"><code>uvicorn</code></a> - 用於加載和運行應用程式的服務器。

* With a Docker Swarm Mode cluster
* With another tool like Nomad
* With a cloud service that takes your container image and deploys it

## Docker Image with Poetry

If you use <a href="https://python-poetry.org/" class="external-link" target="_blank">Poetry</a> to manage your project's dependencies, you could use Docker multi-stage building:

```{ .dockerfile .annotate }
# (1)
FROM python:3.9 as requirements-stage

# (2)
