I am writing a Dockerfile. Is there a way to make comments in this file?
Does Docker have a comment option that takes the rest of a line and ignores it?
7 s
You can use #
at the beginning of a line to start a comment (whitespaces before #
are allowed):
# do some stuff
RUN apt-get update \
# install some packages
&& apt-get install -y cron
#
‘s in the middle of a string are passed to the command itself, e.g.:
RUN echo 'we are running some # of cool things'
