⁠🛡️ Kubernetes Secrets Demo Application 🛡️

⁠Overview

Welcome to the Kubernetes Secrets Demo Application! This Docker image is designed to demonstrate the use of Kubernetes secrets through a simple Flask web application. The application dynamically changes background colours based on the availability of specific secrets, making it easy to visualise whether the secrets are correctly mounted in the Kubernetes pods.

⁠Features

• 💚 Green Background: Displayed when both USERNAME and PASSWORD secrets are mounted.
• 🟧 Amber Background: Displayed when only one of USERNAME or PASSWORD secrets is mounted.
• ❤️ Red Background: Displayed when neither USERNAME nor PASSWORD secrets are mounted.

⁠Getting Started

⁠Prerequisites

• Docker
• Kubernetes
• kubectl

⁠Usage

1. Create Kubernetes Secrets:

   kubectl create secret generic my-secret --from-literal=username=my-app --from-literal=password=s3cr3t
   

   Copy

2. Deploy to Kubernetes:

   Deploy with secrets:

   kubectl apply -f deployment-with-secret.yaml
   

   Copy

   Deploy without secrets:

   kubectl apply -f deployment-without-secret.yaml
   

   Copy

   Create services:

   kubectl apply -f service.yaml
   

   Copy

3. Run the Pod:

   kubectl run podsecrets --image=devopscoderio/podsecrets --restart=Never
   

   Copy

4. Access the Application:

   Check pod status:

   kubectl get pods
   

   Copy

   Port-forward to access services locally:

   kubectl port-forward svc/secret-demo-service 8080:80
   kubectl port-forward svc/secret-demo-no-secret-service 8081:80
   

   Copy

   Access services:

   • With secrets: http://localhost:8080/
   • Without secrets: http://localhost:8081/

⁠Expected Behavior

• 💚 Green Background: When both USERNAME and PASSWORD are mounted.
• 🟧 Amber Background: When only one of USERNAME or PASSWORD is mounted.
• ❤️ Red Background: When neither USERNAME nor PASSWORD is mounted.
