Kubernetes Real-World DevOps Challenges

Learn to Diagnose and Fix Real Kubernetes Production Issues in DevOps and SRE Environments

What you’ll learn
Troubleshoot real Kubernetes production issues like Pod restarts, ImagePullBackOff, and readiness probe failures.
Diagnose and fix high traffic issues using HPA and autoscaling strategies in live cluster scenarios
Resolve application accessibility issues involving Services, Ingress, and networking misconfigurations.
Handle DiskPressure, resource limits, and node-level failures using real-world debugging steps.

Requirements
Basic understanding of Kubernetes concepts like Pods, Deployments, Services, and kubectl commands.
A system with Minikube, Kind, or any Kubernetes cluster installed for hands-on practice.
Basic Linux command knowledge is helpful but not mandatory.

Description
This course teaches what actually happens in production environments — and how to fix it.

If you are working in DevOps, SRE, or Cloud Engineering, you will eventually face

• Pods restarting unexpectedly
• Applications not accessible via browser
• Deployment rollouts stuck
• High traffic causing performance issues
• Nodes under DiskPressure
• Image pull failures
• Readiness probe misconfigurations
• How to diagnose and resolve ImagePullBackOff errors
• How to identify and fix readiness probe failures causing deployment rollout issues
• How to manage Pods evicted due to DiskPressure and node-level resource exhaustion
• How to analyze kubectl outputs including describe, logs, events, and rollout status
• How to identify root causes using structured debugging approaches
• How to correct broken YAML configurations safely
• How to validate fixes and confirm production stability
• How to confidently explain production incidents in interviews
• How to approach production incidents calmly under pressure
• How to document root causes clearly and professionally
• How to implement preventive measures to avoid recurring failures
• How to improve cluster reliability using structured operational practices

This course is designed to prepare you for those real-world challenges.

Course Structure

Each scenario follows a structured format

• Broken configuration setup
• Observing symptoms and impact
• Root cause analysis
• Step-by-step troubleshooting
• Applying the fix
• Validating the solution

By the end of this course, you will think like a production engineer, respond confidently to live incidents, and handle Kubernetes operational challenges in real enterprise environments.
