How to add data to the mongodb

Hi, how do i add data files to the mongodb from my local machine.
Now i have data in my local machine and want to add that data to mongodb through dockerfile.

for ex: if i want to copy some project/war file to tomcat, we do following in the the tomcat docker file
COPY ./soucefile/ ./destination/ 

Likewise, how do i add data to mongodb via docker file

Thanks,
