Trying to use MongoDB with Google Colab by placing the data directory on my Google Drive

Question

I want to use MongoDB from Google Colab. So I need to be able to put my MongoDB data directory on my Google Drive so I don't lose my data from one session to another, but I cannot change the data folder.

1. Mount Google Drive

# Mount Google Drive
from google.colab import drive drive.mount('/content/drive')

2. Install MongoDB on Colab environment

!apt-get install mongodb

3. Stopping the MongoDB service

!service mongodb stop

4. Relaunching the MongoDB service with parameter dbpath to specify the new path

!service mongodb start --dbpath /content/drive/MyDrive/mongodb

5. Using pumongo lib to access database after

import pymongo from pymongo
import MongoClient client = MongoClient()
client.list_database_names() # which return ['admin', 'local']

The problem with my code above is that I can query my Mongo database, but mongodb will still use the path specified in the mongodb.conf file.

# Where to store the data.
dbpath=/var/lib/mongodb

Then I tried to change the path in the mongodb.conf file to

# Where to store the data.
dbpath=content/drive/MyDrive/mongodb

But then I get an error when I restart the mongodb service

* Starting database mongodb
    ...fail!`

What am I forgetting or not doing right at all please?

Thanks for your help
