This pull request introduces the configuration and deployment setup for the weather-app on Kubernetes. The primary changes include the creation of a Kubernetes Deployment, Service, and configuration to ensure the app runs in a scalable and reliable environment.

Changes Included:

• Containerised!:

• Dockerised this application by writing a dockerfile and then creating a docker image.

• Created docker image was pushed to Docker Hub at : https://hub.docker.com/repository/docker/anirbanb13/devops-projects-images/general

• and can pull this docker image for testing purpose using
  docker push anirbanb13/devops-projects-images:latest

• Deployment Configuration:

  • Defined a Deployment to manage the app's pods with 3 replicas.
  • Configured environment variables, including API key injection from a Kubernetes Secret.
  • Added resource requests and limits to optimize pod scheduling.

• Service Configuration:

  • Created a LoadBalancer service to expose the app externally via a stable IP address.

• Namespace Usage:

  • The app is deployed in the weather-app namespace to ensure proper isolation and organization.

• Scaling:

  • Configured the deployment for 6 replicas (scalable as per demand).

---

Changes to Secrets:

• A new secret named weather-app-secret has been created in the weather-app namespace to store the OWM_API_KEY securely. Ensure this secret is created before deployment.

---

Testing:

• Deployment:
  The app was deployed successfully in the weather-app namespace with the desired number of pods.

• Service:
  The service has been exposed externally with a stable IP address via AWS Load Balancer.

---

Next Steps:

• Please verify that the weather-app-secret has been configured properly with the correct API key.
• Confirm that the app is reachable via the exposed LoadBalancer service.

---

Additional Notes:

• The app’s deployment can be scaled further by modifying the replicas count in the Deployment configuration.
• If any issues arise during deployment or testing, please feel free to reach out, and I’ll assist in troubleshooting.
