## 项目历史与用法

Docuum is a Rust command-line daemon for least-recently-used eviction of Docker images. Its purpose is narrow and operational: keep Docker image disk usage below a threshold without deleting images merely because they are old.

### 项目历史

The GitHub repository was created in January 2020. The README explains the motivation as a limitation of Docker's built-in `docker image prune --all --filter until=...`, which uses image creation time rather than last usage time.

### 采用历史

Docuum has specialist adoption among Docker-heavy environments. The official README says it is used by Netflix on production Kubernetes nodes and by Airbnb on a large CI worker fleet. It is also distributed via Homebrew, Cargo, release binaries, and a Docker container.

### 使用方式

Users run `docuum --threshold '10 GB'` manually or as a daemon under launchd, systemd, or NSSM. Docuum listens to `docker system events`, keeps local usage timestamp state, and evicts images when total Docker image disk usage exceeds the configured threshold.

### 为什么软件包爱好者会关心

Docuum is interesting because it packages one missing Docker operational primitive: LRU image cache behavior. It complements Docker's own prune command and BuildKit cache garbage collection rather than replacing either.

### 时间线

- 2020: GitHub repository created.
- 2020s: README documents LRU image eviction based on Docker events and local state.
- 2026: Homebrew packages stable release 0.27.0 and includes a launchd-style service definition.

### Related projects

- Docuum is related to Docker Engine, Docker Compose, BuildKit garbage collection, launchd, systemd, NSSM, and the author's Toast project, all of which are referenced in the README.
