Kue: Devops Blogging Site

Welcome to Kue, a cloud-native devops blogging platform. This project demonstrates modern DevOps practices using Kuernetes, Terraform, Flask, and Docker.

Features

• News Blogging: Create, read, and manage news articles.
• Cloud-Native: Built for scalability and reliability.
• Containerized: All components run in Docker containers.
• Infrastructure as Code: Automated provisioning with Terraform.
• Orchestrated Deployment: Managed using EKSCluster.

Tech Stack

• Flask: Backend web framework (Python)
• Docker: Containerization of application components
• Kuernetes: Orchestration and scaling
• Terraform: Infrastructure provisioning

Getting Started

1. Clone the repository

   git clone https://github.com/utkarshkgit/Kue.git
   cd cloud_blog

2. Provision Infrastructure

   • Configure your cloud provider credentials.

   aws configure

   • Run Terraform scripts in the infrastructure/ directory:

     cd infrastructure
     terraform init
     terraform apply

3. Build and Push Docker Images

   docker build -t <username>/cloud_blog:latest .
   docker push <username>/cloud_blog:latest

4. Deploy to Kuernetes with Network Load Balancer

   • Apply Kuernetes manifests with network-aware deployment:

     aws eks --region us-east-2 update-Kueconfig --name my-cluster
     cd k8s
     
     # Create database secret first
     kubectl create secret generic db-credentials \
       --from-literal=PGHOST=your-db-host \
       --from-literal=PGDATABASE=blogdb \
       --from-literal=PGUSER=your-db-user \
       --from-literal=PGPASSWORD=your-db-password \
       --from-literal=PGPORT=5432
     
     # Deploy with network load balancer
     ./deploy-network-aware.sh

   Alternative manual deployment:

   kubectl apply -f kub.yaml                    # Core application
   kubectl apply -f nginx-loadbalancer.yaml     # Nginx load balancer
   kubectl apply -f network-policy.yaml         # Network policies
   kubectl apply -f hpa.yaml                    # Auto-scaling

5. Access the Application

   • Find the service endpoint and open it in your browser.
