suggestion: when changing path, should file adjust accordingly (?) #13
Description
Currently, if you want to build a Dockerfile in a subdirectory, you'll have to adjust path and file. However, when changing the context using docker build some/other/context, Docker would also prefer the file some/other/context/Dockerfile according to the context (if not specified otherwise).
Should this action also follow this style and use the Dockerfile within path if not otherwise specified? Would be a breaking change but I think it would be more consistent with the Docker CLI experience.
@jerray Happy to submit a PR if you think this idea makes sense.
