Cloud-Native Microservices Application with Kubernetes, Istio, and GitHub Actions Pipeline 🌩️📦🚀

Overview 📖

This project is about constructing a cloud-native microservices application leveraging Kubernetes for orchestration, Istio for service mesh, and incorporating a robust CI/CD pipeline for streamlined deployment processes.

Features ✨

• Microservices Architecture 🏗️: Design and implement several microservices using diverse programming languages and frameworks.
• Containerization 🐳: Utilize Docker to containerize each microservice, creating lightweight and portable containers.
• Orchestration with Kubernetes 🚢: Employ Kubernetes to manage the containerized applications, ensuring scalability, reliability, and efficient resource utilization.
• Service Mesh with Istio 🕸️: Leverage Istio for managing service-to-service communication, traffic routing, and observability within the microservices ecosystem.
• CI/CD Pipeline 🔄: Establish a comprehensive CI/CD pipeline utilizing GitHub Actions for automated testing, building, and deployment.
• Monitoring and Logging 📊: Integrate monitoring and logging tools such as Prometheus and Grafana for effective metrics collection, visualization, and alerting.
• Security 🔒: Apply security best practices including network policies, secrets management, and role-based access control (RBAC) within Kubernetes and Istio environments.
• Fault Tolerance ⚙️: Implement fault tolerance mechanisms like circuit breaking and retries to gracefully handle potential failures.
• Scalability ↕️: Architect the application to scale both horizontally and vertically in response to demand, utilizing Kubernetes autoscaling features.
• Documentation and Testing 📚: Ensure thorough documentation is available for setup, deployment, and ongoing maintenance. Conduct unit tests, integration tests, and end-to-end tests for each microservice.

Getting Started 🚀

Prerequisites

• Docker
• Kubernetes cluster (Minikube, EKS, GKE, etc.)
• Istio service mesh
• GitHub Actions

Installation

1. Clone the repository

   git clone https://github.com/yourgithubusername/yourprojectname.git

2. Set up the Kubernetes cluster

   • If you're using Minikube:

     minikube start --cpus 4 --memory 8192

   • For cloud providers, follow their specific instructions.

3. Install Istio onto the cluster

   Follow the official Istio documentation for installation instructions.

4. Deploy the microservices

   Navigate to the deployment directory and run:

   kubectl apply -f .

5. Set up the CI/CD pipeline

   Configure your chosen CI/CD tool according to the pipeline configuration files included in the repository.

Running the Application

• To access the application, find the external IP of your service:

  kubectl get services

• Open the IP address in your browser or API client to interact with the deployed microservices.
