In this video, we cover Kubernetes PriorityClass — an essential concept for the CKA (Certified Kubernetes Administrator) exam! You’ll learn how to: ✅ Understand PriorityClass and pod scheduling behavior ✅ Create a new PriorityClass named high-priority with a value one less than the highest user-defined class ✅ Patch an existing Deployment (busybox-logger) in the priority namespace ✅ Observe how preemption works when high-priority pods evict lower-priority ones This question is based on CKA Exam Question 7 — follow along and practice it hands-on in your own environment or on my Killercoda labs: 👉 https://killercoda.com/vjain04/scenario/priority-lab 👉 All Labs - https://killercoda.com/vjain04 📚 Commands Used: kubectl get priorityclass kubectl apply -f high-priority.yaml kubectl patch deployment busybox-logger -n priority \ -p '{"spec":{"template":{"spec":{"priorityClassName":"high-priority"}}}}' kubectl rollout status deployment busybox-logger -n priority 💡 Key Takeaways: Higher value = higher pod priority System classes (e.g. system-node-critical) are reserved Use PriorityClass to control scheduling and eviction Preemption automatically frees up resources for critical workloads 🔔 Subscribe for more CKA 2025, Kubernetes, and DevOps hands-on labs from DumbITGuy – DevOps & Cloud the Easy Way! kubernetes,cka,cka exam 2025,cka preparation,cka labs,cka practice question,kubernetes priorityclass,kubernetes scheduling,pod preemption,kubernetes pod eviction,priorityclass example,kubernetes for beginners,kubernetes tutorial,kubernetes devops,ckad exam,ckad preparation,certified kubernetes administrator,kubernetes interview,priorityclass explained,kubernetes crash course,dumbitguy,kubernetes hands-on
