Projektgeschichte

Patrick Hoefler's repository was created in February 2021 and released v0.1.0 the same day. The README frames the tool around a common Docker build problem: multi-stage Dockerfiles become hard to reason about once stages, external images, `COPY --from`, and mount-based dependencies accumulate.

The project continued to receive regular releases through the 0.21.x line by March 2026. Its output model matured around build-stage nodes, highlighted default targets, external-image nodes, and edge styles for `FROM`, `COPY --from`, and `RUN --mount ... from=` dependencies.

Adoptionsgeschichte

dockerfilegraph remains a specialist visualization tool rather than a default Docker workflow. Its install paths still matter to package users: the README documents Docker/ghcr usage, Homebrew installation from the author's tap, mise installation from GitHub, and source builds.

The Homebrew formula API reported stable version 0.21.0, 16 installs in the previous 30 days, and 477 installs in the previous year as of June 30, 2026. That is modest adoption, but credible for a focused Dockerfile architecture/debugging utility.

Wie es verwendet wird

Running `dockerfilegraph` in a project directory generates a graph for `Dockerfile`, with output formats including PDF, SVG, and PNG. Flags support legends, layer display, target filtering, scratch-image handling, separated external-image nodes, and Graphviz layout tuning.

Warum Paket-Nerds sich dafür interessieren

The package is notable because it externalizes Docker build structure into ordinary graph artifacts. It is the kind of CLI package maintainers like: a single executable plus Graphviz turns opaque build-stage relationships into inspectable files for reviews, docs, and debugging.
