Setup

Please do not use this in production!!

1. Clone this repo into databricks repos
2. Go to any of the examples to see how to use them
3. Enjoy your proxy experience :-)
4. If you want to share the link ensure that the other user has permission to attach to your cluster.

Exposing to internet using ngrok

WARNING: IT WILL BE PUBLICLY AVAILABLE TO ANYONE WITH THE LINK SO DO NOT EXPOSE ANYTHING SENSITIVE

The reason for doing this is to test something with a friend or colleague who is not logged in into databricks. The proxy option requires you to be logged in into databricks.

1. Go to ngrok and create an account and get an api token
2. Go to a databricks notebook:

from dbtunnel import dbtunnel

# again this example is with streamlit but works with any framework
dbtunnel.streamlit("<script path>").share("<ngrok-token>").run()
