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.

Who this course is for:

  • DevOps engineers, SREs, Kubernetes administrators, and developers who want real-world troubleshooting skills.
  • Anyone preparing for Kubernetes interviews who wants practical scenario-based learning instead of theory.
  • Professionals preparing for Kubernetes interviews who want practical, scenario-based troubleshooting experience.
  • Anyone working in cloud-native environments who wants confidence in solving production outages step by step.
  • Kubernetes Administrators preparing for real-world operations and incident response scenarios.
