AgrowFarm on Kubernetes
Containerized agriculture web platform deployed on Kubernetes for high availability and scalability
Project Overview
AgrowFarm is an agriculture-focused web platform designed to support digital farming operations, including product listings, services, and scalable access for users. The project was containerized and deployed on Kubernetes to ensure high availability, scalability, and reliable infrastructure management.
🏗️ Architecture Overview
Figure 1: Kubernetes cluster architecture with Ingress, Services, and Pods
The application was containerized using Docker and deployed on a Kubernetes cluster with the following components:
- Kubernetes resources such as Deployments, Services, StatefulSets, and Ingress
- Domain-based routing (agrow.farm, shop.agrow.farm) for external access
- Persistent storage for databases using PV and PVC
- Internal service-to-service communication through ClusterIP services
Technical Implementation
⚙️ Kubernetes Resource Configuration
Each Kubernetes resource was configured using declarative YAML manifests for reproducible and version-controlled infrastructure:
Deployments
Managed stateless application pods with rolling update strategy
- Replicas: 3-5 per service
- Strategy: RollingUpdate (maxSurge: 25%, maxUnavailable: 25%)
StatefulSets
Managed stateful workloads with stable network identities
- Services: PostgreSQL (master/replica), Redis cache
- Storage: PersistentVolumeClaims with 20GB allocated
Services
Network abstraction layer for service discovery and load balancing
- Types: ClusterIP (internal), NodePort (development), LoadBalancer (external)
- Ports: Defined for web (80/443), API (3000), DB (5432)
Ingress Controller
Managed external HTTP/HTTPS traffic routing using Nginx Ingress
- Domains: agrow.farm, shop.agrow.farm, api.agrow.farm
- SSL: LetsEncrypt certificates via cert-manager
ConfigMaps & Secrets
Externalized configuration management for environment variables and credentials
- ConfigMaps: 15+ configuration files
- Secrets: Base64 encoded, mounted as volumes/env vars
Persistent Volumes
Provided persistent storage for databases using dynamic provisioning
- Storage Class: gp2 (AWS EBS)
- Access Modes: ReadWriteOnce, ReadWriteMany
Monitoring & Reliability
- Integrated Prometheus and Alertmanager for cluster and application monitoring
- Metrics collection enabled visibility into pod health, resource usage, and uptime
- Alerts configured for proactive issue detection
- Grafana dashboards for visualization of key metrics
- Log aggregation using EFK (Elasticsearch, Fluentd, Kibana) stack
CI/CD & Operations
- Kubernetes manifests version-controlled for declarative infrastructure management
- Enabled smooth application updates using rolling deployments with minimal downtime
- Improved operational efficiency by automating scaling and recovery using Kubernetes features
- CI/CD pipeline for automated testing and deployment
- Infrastructure as Code using Terraform for cloud resources
- Blue-Green deployment strategy for risk-free releases
