Learning Journey: Part 03 of 16 Module Goal: Master the complete Cluster API object graph: how Cluster, Machine, MachineSet, MachineDeployment, MachinePool, KubeadmControlPlane, BootstrapConfig, and Infrastructure resources relate, delegate, and transfer state. Target Spec: Cluster API v1.14 (v1beta2 APIs). Prerequisites: Part 02: Cluster API Architecture: How the Control Plane Pieces Cooperate (Asynchronous Controller Coordination & Provider Contracts). 1. The Core Challenge: Decoupling Abstraction Overload The most common obstacle when adopting Cluster API (CAPI) is not installation; it is navigating the object graph....

Kubernetes has spent years getting very good at answering one fundamental question: Where should this Pod run? For a large class of traditional applications, that is exactly the right question. A stateless Deployment with ten API replicas usually does not care if replica seven starts 20 seconds after replica six. Each Pod makes progress independently. The scheduler evaluates them one at a time, finds a feasible Node, binds the Pod, and moves to the next item in its queue....

Learning Journey: Part 02 of 16 Module Goal: Understand how core controllers and provider controllers coordinate asynchronously inside the management cluster via CRD references, status conditions, and provider contracts. Target Spec: Cluster API v1.14 (v1beta2 APIs). Prerequisites: Part 01: Kubernetes Cluster API: Kubernetes Managing Kubernetes (Declarative Reconciliation & Management vs Workload mental model). 1. The Core Architecture: Asynchronous Controller Coordination In Part 01, we established the fundamental concept behind Cluster API: a Kubernetes cluster can be expressed as declarative state and managed by controllers....
