Dockerfile Unused Stage Companion
FreeDocker / DevOps
Warning on a named multi-stage Dockerfile build stage (FROM ... AS name) that's never referenced by a later COPY --from=name and isn't the file's own final stage: an orphaned intermediate stage that's real, wasted build time and a confusing read for the next person touching the file, usually left behind after a refactor that moved what it built into another stage.
The gap it fixes
A leftover build stage is easy to miss on review — the Dockerfile still builds fine, it just wastes time building something nothing copies from. Nothing in the IDE flags it today.
