Scheduling, Admission, and Autoscaling

Introduction

This lesson continues the Workloads & Scheduling domain (15% of the CKA, Kubernetes v1.35). The official curriculum asks you to configure workload autoscaling, understand the primitives used to create robust, self-healing application deployments, and configure Pod admission and scheduling (limits, node affinity, etc.). In the performance-based exam these topics produce short, precise tasks: "schedule this Pod only on nodes labelled disk=ssd", "taint a node so only the batch Pods can run there", "cap a namespace at 10 Pods and 4 CPUs", "create an HPA targeting 60% CPU between 2 and 8 replicas", "enforce the restricted Pod Security Standard on a namespace".
