dockerfile, how to support docker run options -d, -v and -p?

Question

I have a very simple dockerfile:

FROM ubuntu:16.04
ADD node-v6.11.1 /usr/local
RUN ln -s /usr/local/bin/node /usr/local/bin/nodejs
RUN node -v
COPY server /server
RUN cd /server && npm install
EXPOSE 80 443
VOLUME ["/server/public"]
CMD cd /server && node server

sudo docker run server works as expected.

sudo docker run server -v /public:/server/public results in: starting container process caused "exec: \\"-v\\": executable file not found in $PATH".

sudo docker run server -d results in: starting container process caused "exec: \\"-d\\": executable file not found in $PATH"

sudo docker run server -p 80:80 gives similar error.

You have to pass the options before the image name as follow:

docker run [OPTIONS] IMAGE [COMMAND] [ARG...]

For example:

sudo docker run -v /public:/server/public server
