Docker를 통해 Discourse를 설치한 지 꽤 되었으며, 지난 몇 년간 여러 번 업그레이드를 수행했습니다. 그러다 보니 docker 이미지들이 꽤 많이 쌓여 있습니다:

```

확실히 모두 아직 필요한 것은 아니겠죠? 최소한의 것만 유지하고 싶다면, 모든 `discourse/base` 이미지와 마지막 `discourse/discourse` 이미지를 정리할 수 있을까요?

`local_discourse/app`, `discourse/base`, `discourse/discourse` 등 서로 다른 이미지 이름들이 무엇인지 혼란스럽습니다.

경험이 있는 분이 최신 3개 정도의 이미지만 유지하는 일반적인 ‘정리(housekeeping)’ 방법을 알려주실 수 있을까요? 저는 docker 전문가가 아니어서…

다음과 같이 시도해 보세요:

```
./launcher cleanup

```
