What We’re Building Today

Picture Netflix deploying new features thousands of times per day across their global infrastructure. How do they ensure every deployment is trackable, reversible, and consistent? The answer is GitOps - treating your Git repository as the single source of truth for infrastructure and application configurations.

Today you’ll build a complete GitOps workflow that automatically deploys your distributed log processing platform whenever configuration changes are committed to Git. By lesson’s end, you’ll have a system that deploys, monitors, and self-heals deployments across multiple environments.

Today’s Learning Objectives:

  • Implement Git-based deployment automation

  • Build reconciliation loop for continuous sync

  • Create deployment validation and rollback mechanisms

  • Integrate with Day 150’s cloud infrastructure templates

  • Deploy web dashboard showing real-time deployment status
