Deployed Voting App using Kubernetes

The project is consist of the below mentioned components:-

• A front-end web app in Python which lets you vote between two options

• A Redis which collects new votes

• A .NET worker which consumes votes and stores them in…

• A Postgres database backed by a Docker volume

• A Node.js web app which shows the results of the voting in real time

Deploying on Kubernetes

The app is deployed using Kubernetes manifests defining Pods, Deployments, and Services to expose and connect components. Here are the high-level steps:

1. Create a Kubernetes cluster: You can use any Kubernetes environment such as Minikube.

2. Apply Deployment manifests: Using kubectl apply -f, deploy each component as a separate pod:

   • vote (Python front-end)

   • redis

   • worker (.NET)

   • postgres

   • result (Node.js)

3. Expose services:

   • Enable the ingress in minikube cluster using the minikube addons enable ingress

   • Create the ingress.ymal and apply it.

   • Expose the svc/ingress-controller

4. Verify the deployment: Use kubectl get pods,svc to ensure all pods are running and services are configured correctly.

5. Access the apps:

   • Visit the voting app via assigned through ingress paths.

   • Vote and watch the results app update dynamically as votes are processed.

This is how you can leverage Kubernetes’ features for service discovery, scaling, and persistent storage, developers can build resilient, scalable, and maintainable cloud-native apps. Thank you for reading any tips will be appreciated.
