How does a push request into Git initiate the CI/CD pipeline?

A push request into Git initiates the CI/CD pipeline primarily through the use of a webhook. When a developer pushes code to a repository, the Git platform can be configured to trigger a webhook, which is an automated notification sent to a specified URL. This notification informs the CI/CD system that new code has been pushed and that it should start the predefined process of building, testing, and deploying the application.

Webhooks act as a bridge between the Git repository and the CI/CD tools, enabling real-time integration and automation of the deployment process. This immediate response to code changes is a fundamental aspect of Continuous Integration and Continuous Deployment practices, allowing teams to deliver updates quickly and efficiently while maintaining high quality.

The other choices do not directly initiate the CI/CD process in the same manner. Scheduled tasks are time-based triggers rather than event-driven, team notifications are typically used for communication purposes and do not directly trigger processes, and manual triggers require human intervention, which is counter to the goal of automation in CI/CD pipelines.
