Superset Chromium Installation

Why we need chromium ?

Chromium is needed for Thumbnails or even to schedule reports. Superset uses selenium internally to capture images for caching thumbnails or scheduling reports in the background to be sent over email or slack. Hence chromium is needed on the os where the superset is installed.

Tutorial to follow along

To install headless Chrome on Ubuntu, you can use the following steps:

1. Install Dependencies:

   sudo apt update
   sudo apt install -y wget apt-transport-https ca-certificates curl gnupg

2. Download and Install Google Chrome:

   First, download the Google Chrome package and add the Google Chrome repository to your system:

   wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
   sudo dpkg -i google-chrome-stable_current_amd64.deb

   If you encounter any dependency issues, you can run the following command to resolve them:

   sudo apt -f install

3. Install the ChromeDriver:

   The ChromeDriver is a separate executable that WebDriver uses to control Chrome. You need to install it separately:

   sudo apt install -y chromium-chromedriver

4. Verify Installation:

   You can verify that Chrome and ChromeDriver are installed correctly by checking their versions:

   google-chrome --version
   chromedriver --version

   The output should display the installed versions of Chrome and ChromeDriver.

5. Set ChromeDriver Path in Superset Configuration (if necessary):

   If you're using Superset and need to specify the path to ChromeDriver in the configuration file, you can set it like this:

   CHROME_DRIVER_PATH = '/usr/lib/chromium-browser/chromedriver'

   Adjust the path as necessary based on where ChromeDriver is installed on your system.

6. Configure Chrome for Headless Mode:

   google-chrome --headless
