# Cron Job: Docker 定期清理

**Job ID:** c933d9df59f5
**Run Time:** 2026-05-24 03:01:34
**Schedule:** 0 3 * * 0

## Prompt

[IMPORTANT: You are running as a scheduled cron job. DELIVERY: Your final response will be automatically delivered to the user — do NOT use send_message or try to deliver the output yourself. Just produce your report/output as your final response and the system handles the rest. SILENT: If there is genuinely nothing new to report, respond with exactly "[SILENT]" (nothing else) to suppress delivery. Never combine [SILENT] with content — either report your findings normally, or say [SILENT] and nothing more.]

执行 Docker 系统清理任务：
1. 运行 docker system prune -a -f 清理悬空镜像和构建缓存
2. 运行 docker volume prune -f 清理未使用的卷
3. 输出清理前后的空间对比

将清理结果输出到终端即可。

## Response

**Docker 系统清理报告**

| 指标 | 清理前 | 清理后 |
|------|--------|--------|
| 磁盘可用空间 | 3.0G | 3.0G |
| 镜像 (Images) | 12个 / 8.726GB | 12个 / 8.726GB |
| 容器 (Containers) | 12个 / 23.53MB | 12个 / 23.53MB |
| 卷 (Volumes) | 8个 / 646MB (7活跃) | 8个 / 646MB (7活跃) |
| 构建缓存 (Build Cache) | 0B | 0B |

**清理操作结果：**
- `docker system prune -a -f` → 回收空间: 0B
- `docker volume prune -f` → 回收空间: 0B

**结论：** 当前系统中所有 Docker 资源均处于活跃使用状态，没有悬空的镜像、未使用的卷或构建缓存可以清理。如果需要释放更多空间，需先停止并删除不需要的容器和镜像喵~
