A Kubernetes cluster consists of two primary logical layers: the Control Plane (the cluster’s brain) and Worker Nodes (the muscle that runs application containers). Understanding how these components communicate is crucial for cluster administration and troubleshooting.
To understand Crossplane, you must first understand the Kubernetes Control Loop. In this episode, we explore the theoretical difference between CLI-driven IaC (Terraform) and Control Plane IaC (Crossplane). We will then install Crossplane into a local cluster using Helm.
A Kubernetes cluster is divided into a Control Plane (the brain) and Worker Nodes (the muscle). Understanding how these components communicate via the declarative REST API is a core requirement for the KCNA exam.
