Tibor Vass b9859b2d49 dockerfile: RUN's CustomName no longer consume quotes and only replaces environment variables if set ... ``` FROM alpine RUN echo "Hey $name" ``` When building the above Dockerfile, the RUN command used to show: `echo Hey ` With this patch it now shows `echo "Hey $name"`. However, because it is very useful for debugging to see the values variables can take, they are expanded if set. ``` FROM alpine ENV name=Jude RUN echo "Hey $name" ``` Building the above Dockerfile makes the RUN command show: `echo "Hey Jude"`.
