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. ### Sources - - - - ## Security Notes broad file, network, media, or database tool signal. formula declares a Homebrew service. - **Geiger risk:** orange / medium - broad file, network, media, or database tool signal - formula declares a Homebrew service ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** docuum - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Other Package-Manager Records - Nix - docuum: normalized package name match | nixpkgs package indexes: pkgs/by-name/do/docuum/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - apk - docuum - 0.26.0-r0: normalized package name match | Alpine Linux edge package indexes: docuum from https://dl-cdn.alpinelinux.org/alpine/edge/community/x86_64/APKINDEX.tar.gz | Perform least recently used (LRU) eviction of Docker images | https://github.com/stepchowfun/docuum - apk - docuum-openrc - 0.26.0-r0: normalized package name match | Alpine Linux edge package indexes: docuum-openrc from https://dl-cdn.alpinelinux.org/alpine/edge/community/x86_64/APKINDEX.tar.gz | Perform least recently used (LRU) eviction of Docker images (OpenRC init scripts) | https://github.com/stepchowfun/docuum ## Related links - [Cloud CLI packages](https://www.automicvault.com/pkg/cloud-clis/) - Belongs to a cloud or infrastructure command family. - [Source-control packages](https://www.automicvault.com/pkg/source-control-tools/) - Belongs to a source-control command family. - [Secret-risk packages](https://www.automicvault.com/pkg/secret-risk-packages/) - Has protected-tool coverage, approval-gate, or non-low Geiger security signals. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [rust](https://www.automicvault.com/pkg/brew/rust/) - Build dependency declared by Homebrew. - [ctop](https://www.automicvault.com/pkg/brew/ctop/) - Shares av.db curated category or tags: cli, containers, docker, system. - [distrobox](https://www.automicvault.com/pkg/brew/distrobox/) - Shares av.db curated category or tags: cli, containers, docker, system. - [conmon](https://www.automicvault.com/pkg/brew/conmon/) - Shares av.db curated category or tags: cli, containers, system. - [crun](https://www.automicvault.com/pkg/brew/crun/) - Shares av.db curated category or tags: cli, containers, system. - [podlet](https://www.automicvault.com/pkg/brew/podlet/) - Shares av.db curated category or tags: cli, containers, system. - [podman](https://www.automicvault.com/pkg/brew/podman/) - Shares av.db curated category or tags: cli, containers, system. - [podman-compose](https://www.automicvault.com/pkg/brew/podman-compose/) - Shares av.db curated category or tags: cli, containers, system. - [podman-tui](https://www.automicvault.com/pkg/brew/podman-tui/) - Shares av.db curated category or tags: cli, containers, system. ## Combined YAML source View the package source record on GitHub.
