In Databricks, the “host” refers to your specific Databricks workspace URL. Here’s how to find it and use it with the Databricks CLI:

Finding Your Databricks Host

1. Log in to Databricks:  Go to your Databricks workspace.
2. Look at the URL: Your Databricks workspace URL will be in your browser’s address bar. It will have the following format:
3. https://<region>.cloud.databricks.com/ 
   • Replace <region> with the actual area where your Databricks workspace is located (e.g., “dbc-a1b2345c-d6e7” if it’s in Azure).

Using the Databricks CLI

The Databricks CLI is a command-line tool that lets you interact with your Databricks workspaces from your terminal. Here’s how to use your host with the CLI:

1. Install the Databricks CLI: Follow the instructions at https://docs.databricks.com/en/dev-tools/cli/index.html.
2. Configure the CLI:
   • Run databricks configure –token.
   • When prompted for “Databricks Host,” enter the URL you found earlier.
   • When prompted for “Token,” provide a Databricks personal access token (you can generate one from your Databricks workspace settings)

Example

Let’s say your Databricks host URL is https://dbc-a1b2345c-d6e7.cloud.databricks.com. Here’s how you’d configure:

Bash

data bricks configure –token

Databricks Host (should begin with https://): https://dbc-a1b2345c-d6e7.cloud.databricks.com

Token: <your personal access token> 

Important Notes:

• Protect your tokens: Never share your Databricks personal access token, as it gives access to your workspace.
• CLI for convenience: The Databricks CLI provides a simple way to manage Databricks resources (create jobs, manage clusters, upload files, etc.) from the command line.
