🚀 Kubernetes Mastery – Lesson 5-1: Pod Scheduling with Resource Boundaries

How does Kubernetes decide where your Pods run?

Behind every Pod creation is one of the most critical control plane components: the Kubernetes Scheduler. It evaluates resource availability, constraints, and policies to determine the best possible node for your workload.

In this lesson, we dive deep into Resource Requests and Resource Limits — the foundation of intelligent scheduling and stable production systems.

📘 Course Structure

This course consists of 8 structured lessons, each starting with a conceptual introduction followed by focused, hands-on videos.

In Certified Kubernetes Administrator – Kubernetes Mastery: From Cluster Setup to Troubleshooting, you’ll learn how to:

• Build and configure Kubernetes clusters from scratch
• Manage workloads, Deployments, Pods, and core configurations
• Master scheduling rules, node affinities, and automation tools
• Expose applications using Services and Ingress
• Configure storage and persistent volumes
• Debug, troubleshoot, and fix real-world Kubernetes issues

Through practical explanations and real-world architecture thinking, you’ll gain the confidence to operate production-ready clusters.

📚 Learning Agenda (This Video)

Understanding the Kubernetes Scheduler:
• How scheduling decisions are made
• Why resource definitions directly affect placement

Resource Requests (The “Ask”):
• Guaranteed minimum CPU and memory
• How the scheduler evaluates node capacity
• What happens when no node satisfies the request

Resource Limits (The “Ceiling”):
• Runtime enforcement by kubelet
• CPU throttling vs Memory OOMKill
• Demonstrating OOMKill behavior with a live example

Hands-On Demonstrations:
• Multi-container Pod scheduling
• Inspecting node capacity & allocatable resources
• Simulating Memory OOMKill
• Demonstrating CPU throttling effects

Best Practice:
• Why you must always define BOTH requests and limits
• Understanding Burstable QoS

🧠 Why This Matters for CKA

For the CKA exam — and real production environments — understanding:

• How the scheduler uses requests
• Why limits protect cluster stability
• The difference between throttling and OOMKill

is absolutely critical.

Misconfigured resource boundaries can lead to:
• Pods stuck in Pending
• Node starvation
• Unstable applications
• Production outages
