Build a mongo container and import data

Question

I want to build a Mongo container, and insert some data stored in the folder /mongo_mock_data in this container. Here are my lines of code:

MONGO_ID=$(docker run --publish-all -d --mount type=bind,source=${PWD}/mongo_mock_data,target=/tmp/mongo_mock_data mongo)
MONGO_PORT=$( docker inspect $MONGO_ID |  jq -r '.[0].NetworkSettings.Ports."27017/tcp"[0].HostPort' )
MONGODB_URL=mongodb://localhost:${MONGO_PORT}
docker exec $MONGO_ID mongoimport --host $MONGODB_URL --db algo --collection train --type json --file /tmp/mongo_mock_data/train_data.json --jsonArray
docker exec $MONGO_ID mongoimport --host $MONGODB_URL --db algo --collection calculation --type json --file /tmp/mongo_mock_data/predict_data.json --jsonArray
docker exec $MONGO_ID mongoimport --host $MONGODB_URL --db algo --collection train --type json --file /tmp/mongo_mock_data/cluster_data.json --jsonArray

I have the following error:

error parsing command line options: error parsing URI from mongodb:///localhost:32773/?replicaSet=mongodb:: error parsing uri: must have at least 1 host

any ideas what Im doing wrong?

EDIT:

If I try:

MONGODB_URL=localhost:${MONGO_PORT}
docker exec $MONGO_ID mongoimport --host $MONGODB_URL --db pulse_algo --collection train --type json --file /tmp/mongo_mock_data/train_data.json --jsonArray

instead of

MONGODB_URL=mongodb://localhost:${MONGO_PORT}
docker exec $MONGO_ID mongoimport --host $MONGODB_URL --db algo --collection train --type json --file /tmp/mongo_mock_data/train_data.json --jsonArray

I have the following error:

error connecting to host: could not connect to server: server selection error: server selection timeout

Is the third slash in mongodb:/// a transcription error? If not, then what is happening is that MongoDB is trying to connect to a server at '' (ie, nothing) to a database named localhost:32773, rather than a server at localhost:32773 & the default database.

This is not a transcription error, but I dont get what you mean? I edited my question with the assignment of MONGODB_URL

So, finally, I solved my issue by dropping the argument --host:

MONGO_ID=$(docker run --publish-all -d --mount type=bind,source=${PWD}/mongo_mock_data,target=/tmp/mongo_mock_data mongo)
MONGO_PORT=$( docker inspect $MONGO_ID |  jq -r '.[0].NetworkSettings.Ports."27017/tcp"[0].HostPort' )
docker exec $MONGO_ID mongoimport --db algo --collection train --type json --file /tmp/mongo_mock_data/train_data.json --jsonArray
docker exec $MONGO_ID mongoimport --db algo --collection calculation --type json --file /tmp/mongo_mock_data/predict_data.json --jsonArray
docker exec $MONGO_ID mongoimport --db algo --collection train --type json --file /tmp/mongo_mock_data/cluster_data.json --jsonArray

In my case, I was getting this error because of passing option --csv instead of --type=csv to mongoexport. Correction of that fixed this issue.

mongoexport type options

Error message could've been better.
