我正在整理系统，通过这样做刚刚释放了 28GB 空间。
请确保所有论坛都在运行（即未停止），然后执行：
docker system prune
并确认输入 Y。
还有其他人这样做吗？Discourse 团队是否常规推荐这样做（或推荐其他操作）以维护我们的 Discourse 实例？

清理实际上会调用 docker prune：

是否可以通过管理界面在升级后触发清理过程？
Prune 在主机级别运行，而 admin 升级则在运行中的容器内部进行。
此外，/.launcher cleanup 会清理旧镜像，但在使用内部 admin 升级时，甚至不会下载新镜像。

没错。也许流程最近有所变化，但我记得以前不得不手动清理大量旧镜像，因为它们占用了磁盘空间。而升级到最新版本后，我现在只剩下几个旧镜像了。
帮大忙了。谢谢，./launcher cleanup 效果很好。
