🚀 K8s SRE Project Dashboard

📋 About This Project

This is a comprehensive Kubernetes Site Reliability Engineering (SRE) platform demonstrating microservices deployment, observability, testing, and GitOps practices. The project showcases modern cloud-native technologies and best practices for running production workloads on Kubernetes.

The platform includes a complete microservices e-commerce application (Online Boutique), comprehensive monitoring and logging, continuous delivery via GitOps, and automated testing frameworks for reliability assurance.

🛍️ Online Boutique Microservices

A Google Cloud microservices demo application showcasing a 12-tier e-commerce application. The application consists of multiple microservices written in different languages (Java, Go, Python, Node.js, C#) communicating via gRPC and HTTP.

Namespace: online-boutique

Services: frontend, cartservice, checkoutservice, productcatalogservice, recommendationservice, currencyservice, paymentservice, shippingservice, emailservice, adservice, redis-cart

🧪 Testing Frameworks

Sanity Test

Automated health check framework that continuously validates the health endpoints of all microservices in the online-boutique namespace. It tests connectivity, response times, and service availability for each microservice (gRPC, HTTP, and TCP protocols).

Namespace: sanity-test

Tests: All microservices in online-boutique namespace

Availability Test

Continuous availability testing framework that runs periodic tests (every 5 minutes) on critical services (Cart Service and Frontend Service). It provides a dashboard showing test history, success rates, and failure analysis.

Namespace: availability-test

Test Interval: 300 seconds (5 minutes)

Tests: Cart Service, Frontend Service

🔄 Continuous Delivery (GitOps)

ArgoCD is used for GitOps-based continuous delivery, automatically syncing applications from Git repositories to Kubernetes clusters. All deployments are managed declaratively through Git, ensuring version control, audit trails, and consistent deployments.

Internal URL: https://argocd-server.argocd.svc.cluster.local:443

Namespace: argocd

Applications Managed:

• Microservices Demo (online-boutique)
• Monitoring Stack (Prometheus, Grafana, Loki)
• Availability Test Framework
• Sanity Test Framework

Features:

• Automatic sync from Git repositories
• Self-healing deployments
• Application health monitoring
• Rollback capabilities

📊 Monitoring & Observability

Comprehensive observability stack providing metrics, logs, and visualization for the entire Kubernetes platform. The stack follows industry best practices for monitoring cloud-native applications.

Prometheus

Namespace: monitoring

What it monitors:

• Kubernetes cluster metrics (nodes, pods, services)
• Application metrics from microservices
• Kube State Metrics (cluster state)
• Node Exporter (host metrics)

Grafana

Namespace: monitoring

Data Sources: Prometheus (metrics), Loki (logs)

Features:

• Pre-configured dashboards for Kubernetes monitoring
• Custom dashboards for microservices
• Log exploration with LogQL
• Metrics visualization with PromQL
• Alerting and notification rules

Loki

Namespace: monitoring

Log Collection: Promtail (DaemonSet) collects logs from all pods

Access: Via Grafana Explore (Loki data source)

Features:

• Centralized log aggregation from all namespaces
• LogQL query language (similar to PromQL)
• Label-based log indexing
• Log retention and storage
