Kubernetes Pod Priority & Preemption  Explained | Making Sure the Right Workloads Run First

Not all workloads in Kubernetes are equal — some services must run no matter what, while others can wait. So how does Kubernetes decide which pods get resources first when the cluster is under pressure? In this video, we clearly explain Pod Priority and Preemption, a core Kubernetes scheduling concept that helps clusters stay reliable during high load, traffic spikes, or limited capacity. This is a conceptual, architecture-level explanation, focused on how Kubernetes thinks 🔍 What you’ll learn in this video Why Kubernetes needs Pod Priority What PriorityClass is and how it works How the Kubernetes scheduler orders pods What Preemption means internally When and why lower-priority pods get evicted Pod Priority vs QoS classes (common confusion) Limitations, risks, and edge cases of preemption Best practices for using priority safely in production ⏱️ Video Timeline 00:00 – Why Pod Priority exists 00:35 – The Kubernetes scheduling problem 01:20 – What is Pod Priority 02:05 – Understanding PriorityClass 03:00 – How scheduling order changes 03:45 – What is Preemption 04:40 – When Kubernetes evicts pods 05:25 – Pod Priority vs QoS 06:15 – Limitations & risks 07:00 – Production best practices 07:40 – Final summary 🧠 Who should watch? Kubernetes beginners building fundamentals DevOps Engineers Site Reliability Engineers (SREs) Platform & Infrastructure Engineers Engineers preparing for CKA / CKAD / Kubernetes interviews ⚠️ Important takeaway Pod Priority and Preemption are powerful — but dangerous if misused. Used correctly, they protect critical services. Used carelessly, they can destabilize your cluster. Understanding this balance is key to running Kubernetes in production. 👍 If this explanation helped you understand Kubernetes scheduling better, like, share, and subscribe to vcloudlabs for more real-world Kubernetes & DevOps content.
