プロジェクトの歴史

The project README explains the origin in a practical operations problem: the author needed to visualize and inspect a large dockerized legacy system with more than 470 containers and little documentation. That origin shaped the tool as a reverse-engineering utility rather than a deployment orchestrator.

The official release stream shows decompose reaching v0.9.1 in August 2023 and v1.0.0 the next day, with later 1.x releases continuing through 2026.

採用の歴史

decompose is packaged for Homebrew and also distributed upstream as release binaries, deb and rpm packages, and a Docker image. That makes it usable both as a local terminal tool and as a throwaway container for infrastructure inspection.

使われ方

Package users run decompose when they need an observed map of an existing Docker estate. The README emphasizes stdout-oriented Unix behavior, sorted output for version control, offline processing from saved JSON streams, metadata enrichment, and multiple graph/export formats.

パッケージ好きにとっての重要性

decompose is interesting to package people because it sits between Docker introspection, graph tooling, and documentation recovery. It is a small CLI that packages a messy operational task - discovering what containers actually talk to - into reproducible text outputs.

タイムライン
