history
Project history and usage
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.
Project history
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.
Adoption history
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.
How it is used
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.
Why package nerds care
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.
Timeline
- 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.
