Learning GitHub Actions for DevOps CI/CD - Default GitHub Variables

The video tutorial explores default environment variables set by GitHub, which provide information about the current workflow run and the runner executing it. The instructor demonstrates a workflow with jobs for Ubuntu, Windows, and Mac, each printing environment variables. The tutorial emphasizes the usefulness of these variables for fetching workflow-related information and encourages experimentation. An example is provided, showing how to print common GitHub variables for an Ubuntu runner, highlighting the potential for curiosity-driven learning.
