## Offizielles Docker-Image mit Gunicorn – Uvicorn

Es gibt ein offizielles Docker-Image, in dem Gunicorn mit Uvicorn-Workern ausgeführt wird, wie in einem vorherigen Kapitel beschrieben: [Serverworker – Gunicorn mit Uvicorn](server-workers.md){.internal-link target=_blank}.

그리고 <a href="https://hub.docker.com/" class="external-link" target="_blank">도커 허브</a>에 다양한 도구, 환경, 데이터베이스, 그리고 어플리케이션에 대해 미리 만들어진 **공식 컨테이너 이미지**가 공개되어 있습니다.

예를 들어, 공식 <a href="https://hub.docker.com/_/python" class="external-link" target="_blank">파이썬 이미지</a>가 있습니다.

또한 다른 대상, 예를 들면 데이터베이스를 위한 이미지들도 있습니다:

* <a href="https://hub.docker.com/_/postgres" class="external-link" target="_blank">PostgreSQL</a>
