Kubernetes Portfolio Hosting Infrastructure

Production-ready Kubernetes infrastructure hosting a portfolio website on Rackspace spot instances with high availability and persistent storage.

Infrastructure Setup

• 2 Rackspace Spot Instances: 16GB RAM, 4 vCPU each
• Kubernetes Cluster: Multi-node deployment
• Nginx Service: Layer 7 load balancer
• Persistent Volume: Shared storage for large files

Implementation

Load Balancing

• Nginx service distributes traffic across two portfolio pods
• Each pod runs on a separate instance for high availability
• Automatic failover and even traffic distribution

Storage Management

• Persistent Volume (PV) created for large file storage
• Temporary pod used to upload and transfer files to volume
• Volume bound to main deployment for persistent access across pod restarts

Architecture

Two-tier deployment with Nginx handling incoming traffic and distributing requests across portfolio pods on separate instances. Persistent storage mounted to deployments ensures data survives pod lifecycle events.

Achievements

• Zero downtime deployments with multi-pod distribution
• Cost-optimized using spot instances while maintaining reliability
• Efficient large file management through temporary pod workflow

Technologies

• Kubernetes
• Nginx (Service Load Balancer)
• Rackspace Cloud (Spot Instances)
• Persistent Volumes (PV/PVC)
• Docker
