Import MongoDB Data

The MongoDB data is usually a jsonArray which cannot be imported via MongoExpress GUI The solution is to use mongoimport through the cli

1. Download data

wget <DOWNLOAD_LINK>

2. Move data to container. Using the same terminal where the MongoDB container was run, type the following:

docker cp <SOURCE_PATH> <MONGO_CONTAINER_NAME | MONGO_CONTAINER_ID>:<DESTINATION_PATH>

3. execute the mongoimport command

Method 1: Exec

3. 1. a. Use the exec command to execute the mongoimport command in the container:

docker exec <MONGO_CONTAINER_NAME | MONGO_CONTAINER_ID> mongoimport -h localhost:27017 -u <ADMIN_USERNAME> -p <ADMIN_PASSWORD> --authenticationDatabase=<CREDENTIALS_DB | admin>  -d <DATABASE_NAME> -c <COLLECTION_NAME> --type json --file <FILE_NAME> --jsonArray

Method 2: Bash

3. 2. a. Access bash. Using the same terminal where the MongoDB container was run, type the following:

docker exec -it <MONGO_CONTAINER_NAME | MONGO_CONTAINER_ID> bash

3. 2. b Use mongoImport to import data with the following command:

mongoimport -h localhost:27017 -u <ADMIN_USERNAME> -p <ADMIN_PASSWORD> --authenticationDatabase=<CREDENTIALS_DB | admin> -d <DATABASE_NAME> -c <COLLECTION_NAME> --type json --file <FILE_NAME> --jsonArray
