Upload local files to docker container

There is the following code In my Dockerfile :

ENV GOVERS 073fc578434b

RUN cd /usr/local && curl -O http://go.googlecode.com/archive/$GOVERS.zip
RUN cd /usr/local && unzip -q $GOVERS.zip

the above code downloads the zip file to the /usr/local directory and all is ok. But now i do not want to download the zip file, I want to get the zip file from my local PC to the /usr/local at the docker container.

Another approach that I am starting to like is using volumes and runtime commands. I don't like to have to rebuild the image if I change something incidental.

So I create a volume in the docker file to transfer stuff back and forth: In Docker file:

RUN mkdir -p /someplace/dropbox
....
CMD ..... ; $POST_START ; tail -f /var/log/messages

on host:

mkdir /dropbox && cp ~/Downloads/fap.zip /dropbox \
 docker run -v /dropbox:/someplace/dropbox  \
   -e POST_START="cp /someplace/dropbox/fap.zip /someplace-else; cd /someplace-else;unzip fap.zip" ..... <image>

Let say the zip file is named test.zip and is located in the same directory as your Dockerfile, then you can make use of the COPY instruction in your dockerfile. You will then have:

COPY test.zip /usr/local/
RUN cd /usr/local && unzip -q test.zip

Furthermore you can use the ADD instruction instead of COPY to also uncompress the zip file and you won't need to RUN the unzip command:

ADD test.zip /usr/local/
