Project Overview

A personal Kubernetes project focused on running a containerized web application reliably inside a Kubernetes cluster. The deployment uses Kubernetes-native resources for application lifecycle management, networking, configuration, health checks, and scaling.

Portfolio note: This is presented as a personal project concept/implementation. Only describe it as completed after you have actually built, tested, and documented the deployment.

Architecture

Kubernetes Cluster │ ┌────────▼────────┐ │ Service │ └────────┬────────┘ │ ┌──────────────┴──────────────┐ ▼ ▼ Deployment Pod #1 Deployment Pod #2 App Container App Container │ │ └──────────────┬──────────────┘ ▼ ConfigMap / Secret Readiness + liveness probes control application health.

Implementation

  1. Build a small web application container and publish the image to a container registry.
  2. Create Kubernetes Deployment and Service manifests.
  3. Use ConfigMaps for non-sensitive configuration and Secrets for sensitive values.
  4. Add readiness and liveness probes for safer traffic routing and restarts.
  5. Configure resource requests and limits for predictable scheduling.
  6. Test rolling updates, scaling, service connectivity, and failure recovery.
