Kubernetes Debugging Workshop

This workshop provides hands-on exercises focused on common debugging tasks in Kubernetes. Each exercise is designed to simulate real-world issues developers and operators might encounter while working with Kubernetes-managed applications, such as:

• Pods failing to start due to incorrect configurations or missing resources.
• Connectivity issues between services and their pods.
• Applications failing due to misconfigured ConfigMaps or missing Secrets.
• Pods getting stuck in CrashLoopBackOff states.
• Problems with resource limits causing throttling or crashes.
• Persistent volume claims not being bound or accessible.
• Network policies blocking traffic unexpectedly.
• Misconfigured readiness or liveness probes.
• Issues with Ingress routing making applications inaccessible.

Workshop Overview

• Audience: Developers and operators using managed Kubernetes clusters.
• Focus: Debugging common application issues in Kubernetes.
• Cluster Setup: A shared workshop cluster where each participant works in their own namespace.

Directory Structure

Each exercise is in a separate directory. Each directory contains:

• A README.md file with the exercise description, setup instructions, and cleanup steps.
• A manifests/ directory with YAML files needed to create the exercise scenario.

Solutions

The solutions for these exercises will be kept separate to prevent students from cheating.
