Kubernetes Infrastructure Automation
Overview
This project involved automating Kubernetes cluster management using Infrastructure as Code (IaC) principles. The goal was to create a scalable, maintainable infrastructure setup that could be version-controlled and deployed consistently across multiple environments.
Technologies Used
- Terraform for infrastructure provisioning
- Helm charts for Kubernetes application deployment
- Kustomize for environment-specific configurations
- GitHub Actions for CI/CD automation
- AWS EKS for managed Kubernetes clusters
Key Features
- Automated cluster provisioning with Terraform
- Multi-environment support (dev, staging, production)
- Helm-based application deployments
- Automated CI/CD pipelines for infrastructure changes
- Infrastructure versioning and rollback capabilities
Challenges & Solutions
One of the main challenges was managing different configurations across environments while maintaining consistency. This was solved by using Kustomize overlays that allowed environment-specific customizations while keeping a common base configuration.
Another challenge was ensuring security best practices. I implemented RBAC policies, network policies, and secrets management using AWS Secrets Manager integrated with Kubernetes.
Results
The automation reduced deployment time from hours to minutes. Infrastructure changes could now be reviewed through pull requests, ensuring better collaboration and reducing human errors. The setup also enabled quick disaster recovery through infrastructure recreation from code.
