How to Explain Deploying a Web App on Kubernetes During an Interview?

Deployment in Kubernetes can be multi-faceted, so don't just stick to one method. Show your flexibility by mentioning tools for automated deployment and the importance of configurations like service accounts and HPA in your overall strategy to achieve scalability and reliability.

When asked about deploying a web app on K8s, start by explaining whether you'll be doing it manually or using tools like GitOps. They want to see your understanding of different methods. A solid answer would cover packaging your app into a container image, storing it in a container registry, and then creating a Kubernetes deployment resource to run your app in the cluster. Don't forget to mention other resources like services, ingress, volumes, and Horizontal Pod Autoscaler (HPA) if they fit the scenario.

To deploy a web app on Kubernetes, you'll want to first create a container image of your application and push it to a container registry. Then, you'll define a deployment in your K8s YAML that uses the image to ensure your app is running smoothly in the cluster. Remember to also think about additional resources like services for networking, ingress for managing external access, and volume claims for storage!

I suggest giving recruiters a feeler question, asking candidates how they'd approach the problem before jumping into specifics. This can help you gauge their understanding of concepts like stateful sets and persistent volume claims. It's also useful to see if they touch upon newer features like GatewayAPI when discussing ingress replacements.
