It will be made public in 48 hours. In this lecture, we move one level deeper into Argo CD by focusing on Application CRDs, which are the heart of how Argo CD implements GitOps in Kubernetes. Before jumping directly into Application CRDs, we first revisit Kubernetes resources, CRDs, and controllers, building a clear foundation for why Application CRDs exist and why they are modeled the way they are. Without this understanding, Application CRDs can feel opaque or magical. We then explain what an Application CRD really is, what it represents, how it connects Git and Kubernetes, and how Argo CD uses it to continuously reconcile desired state. Finally, we deploy a real application using an Application resource and observe Argo CD reconciliation in action. This lecture is critical for understanding how GitOps becomes real inside Kubernetes. 🛠 *What You’ll Learn Today* What Kubernetes CRDs are and why they exist How CRDs relate to controllers and reconciliation What the Argo CD Application CRD represents Application CRD vs Kubernetes manifests Source and destination in an Application resource How Argo CD tracks and reconciles applications Manual sync vs reconciliation-driven deployments Hands-on demo: deploying an app using Application CRD ⏰ Timestamps 00:00:00 Introduction 00:01:27 What are CRDs?
