GitOps Demo Project

Overview

This project implements a modern cloud-native infrastructure using GitOps principles, combining the power of GitHub Actions, Azure Kubernetes Service (AKS), and robust monitoring solutions. The architecture ensures continuous deployment, secure operations, and comprehensive system observability.

Architecture Components

CI/CD Pipeline

The project leverages GitHub Actions as the primary CI/CD solution, providing:

• Automated build and test processes
• Continuous deployment to AKS
• Integration with GitOps workflows
• Automated security scanning and quality checks

Cloud Infrastructure

Azure Kubernetes Service (AKS) serves as our container orchestration platform, offering:

• Scalable container deployment
• Built-in security and compliance
• High availability and disaster recovery
• Integration with Azure services

GitOps Implementation

Our GitOps approach uses GitHub as the single source of truth, ensuring:

• Infrastructure as Code (IaC) practices
• Automated synchronization between Git and cluster state
• Version control for all configurations
• Automated drift detection and remediation

Secret Management

The project implements a multi-layered secret management strategy:

• SOPS (Secrets OPerationS) for Git-stored encrypted secrets
• Azure Key Vault integration for secure secret storage
• Kubernetes Secrets for runtime configuration
• Encryption at rest and in transit

Monitoring and Observability

The monitoring stack consists of:

Prometheus

• Metrics collection and storage
• Performance monitoring
• Resource utilization tracking
• Custom metrics support

Grafana

• Customizable dashboards
• Real-time data visualization
• Performance analytics
• Trend analysis and reporting

Alertmanager

• Alert routing and grouping
• Notification management
• Alert deduplication
• Customizable alert rules

Self-Healing Capabilities

The infrastructure implements automatic recovery mechanisms through:

• Kubernetes liveness probes
• Automatic pod restarts
• Resource limits and scaling
• Health check endpoints

Project Benefits

• Consistency: Guaranteed alignment between Git configuration and cluster state
• Security: Multi-layered security approach with encrypted secrets and access controls
• Observability: Comprehensive monitoring and alerting system
• Reliability: Self-healing capabilities and automated recovery
• Scalability: Cloud-native architecture supporting dynamic scaling
• Automation: Reduced manual intervention through GitOps practices
