DevOps Troubleshooting Interview

Welcome to the DevOps troubleshooting challenge! This repository contains a Kubernetes application with several intentional issues that you need to identify and fix.

Prerequisites

• k3d installed
• kubectl installed
• Docker (colima, Docker Desktop, or similar)
• Basic understanding of Kubernetes concepts

Setup

1. Clone this repository:

git clone <repository-url>
cd <repo-name>

2. Make the init script executable and run it:

chmod +x init.sh
./init.sh

This will create a k3d cluster with nginx ingress controller installed.

Your Task

The deployment manifests contain multiple issues across different Kubernetes resources. Your goal is to:

1. Deploy the application:

   kubectl apply -f manifests/

2. Identify and fix all issues to get the application fully functional

3. Verify success: The application should be accessible at http://localhost:8080 and display a success message

Expected Outcome

When all issues are resolved:

• All pods should be in Running state with READY status
• Ingress should route traffic correctly
• Accessing http://localhost:8080 should display a congratulations page

Cleanup

To remove the cluster when done:

k3d cluster delete devops-interview

Good luck!
