How to write commands with multiple lines in Dockerfile while preserving the new lines?

Question

I want to write the following RUN command in the Dockerfile. But, docker is not preserving the new lines.

RUN echo \"[repo] \\
name            = YUM Reposito         


        

Answer 1

I ended up using a combination of the examples listed above since the new line \n did not work with echo.

RUN printf 'example \n\
text \n\
here' >> example.txt

It produces the following, as expected:

example
text
here
