   superset run -p 8088 --with-threads --reload --debugger

9. Access Superset by visiting http://localhost:8088 and logging in with the credentials you created.

Initializing the Superset Database

To set up the Apache Superset database, follow these guidelines:

1. Install Apache Superset: Utilize pip, the Python package manager, to install Superset.

   pip install apache-superset

2. Database Initialization: Execute the following command to upgrade the database to the latest version.

   superset db upgrade

3. Admin User Creation: Define the FLASK_APP environment variable and create an admin user.

   export FLASK_APP=superset superset fab create-admin

4. Load Examples: If desired, load example data using the following command:

   superset load_examples

5. Initialize Superset: Establish default roles and permissions with the superset init command.

6. Build Assets: Navigate to the superset-frontend directory, install dependencies, and build the frontend assets.

   cd superset-frontend npm ci npm run build cd ..

7. Run Development Server: Start the development server on port 8088 or any preferred port.

   superset run -p 8088 --with-threads --reload --debugger

Following these steps ensures Superset's database is set up correctly. Access Superset by visiting http://localhost:8088 in your browser and logging in with the credentials you created.

Creating an Admin User via Superset CLI

To create an admin user in Apache Superset using the command line interface (CLI), follow these steps after you have Superset installed:

1. Set the FLASK_APP environment variable to superset:

   export FLASK_APP=superset

2. Use the superset fab create-admin command to start the process:

   superset fab create-admin

You will be prompted to enter the admin's username, first and last name, email, and password.

1. After creating the admin user, you should initialize the database with the default roles and permissions by running:

   superset init

This process registers the admin user in the metadata database, allowing them to log in to the Superset instance. Remember to follow best practices for securing your admin credentials.

Loading Example Data with Superset CLI

Apache Superset offers a convenient command-line interface (CLI) for loading example data, aiding users in familiarizing themselves with the platform's capabilities. Below are the steps to load CSV data and example datasets using the Superset CLI:

1. Load CSV Data:

   • Download the CSV dataset from the provided GitHub link.

   • In Superset, navigate to Data ‣ Upload a CSV.

   • Specify the Table Name as "tutorial_flights" and select the downloaded CSV file.

   • Enter "Travel Date" in the Parse Dates field.

   • Keep other options as default and click Save.

2. Load Example Data and Dashboards:

   • Create a file named "my_values.yaml".

   • Deploy the configuration as instructed in the Configure your setting overrides section.

3. Log in to Superset:

   • Access your local Superset instance at http://localhost:8088.

   • Log in using the default credentials:

     • Username: admin

     • Password: admin

Add the following configuration to enable loading examples:

init: load

Examples: true

Following these steps allows users to efficiently import data into Superset and begin exploring its features. The CLI commands simplify the setup process, facilitating a smoother start to data analysis.

Configuring Superset with the CLI
