Expected behavior

In a multi-stage Dockerfile, in the build stage(s) we want as many RUN instructions as possible to cache the steps.

https://docs.docker.com/build/building/multi-stage/

Actual behavior

hadolint scans all parts of the file and not only the run stage.

Steps to reproduce the behavior

Look at Dockerfile bellow.

Error: Dockerfile:11 DL3059 info: Multiple consecutive RUN instructions. Consider consolidation.
Error: Dockerfile:12 DL3059 info: Multiple consecutive RUN instructions. Consider consolidation.
Error: Dockerfile:13 DL3059 info: Multiple consecutive RUN instructions. Consider consolidation.
