Github workflow triggers

• Events that trigger workflows
• Manually run a workflow
• Workflow call is when one workflow is called by other which is generally reusing workflows Refer Here

Continuous Integration

* Watch classroom recording for codeql scans
* Exercise: Try setting up a sonar cloud workflow with your public springpetclinic
