# Assuming there's a Docker container runninng Mongo, named `mongo1`,
# fire up another container `mongo2`,
# mounting a directory containing data to import,
# and execute `mongoimport` inside `mongo2`,
# to import data into `mongo1`.

# Start `mongo2`:
# link it to the running `mongo1`;
# open a bash session;
# mount pwd to /import;
# remove when done.
docker run --rm -it --link mongo1 --network my_network -v $(pwd):/import mongo:3 /bin/bash

# Now, inside `mongo2`, run `mongoimport`
# to import data from a file into `mongo1`.
mongoimport --uri mongodb://mongo1/db?replicaSet=rs --drop --collection=some_collecdtion /import/some_file.json
