DBCostOps - Database DevOps Cost Optimizer

A comprehensive database DevOps platform that automates database infrastructure management, optimizes costs across multiple database engines, and provides GitOps-style database operations with real-time cost analysis and resource optimization.

🚀 Quick Start

Prerequisites

• Docker & Docker Compose
• Git
• 8GB+ RAM (16GB recommended)
• 4+ CPU cores (8+ recommended)

Installation

1. Clone and Setup

git clone <repository-url>
cd DBCostOps

2. Start All Services

docker-compose up -d

3. Initialize Services

# Wait for services to start (2-3 minutes)
# Initialize Puppet environment
docker-compose exec puppet-server puppetserver ca generate

# Initialize databases
docker-compose exec postgres-primary psql -U dbcostops_user -d dbcostops -c "CREATE EXTENSION IF NOT EXISTS pg_stat_statements;"
docker-compose exec mysql-primary mysql -u root -proot_password -e "CREATE DATABASE IF NOT EXISTS rundeck;"
docker-compose exec mongodb-primary mongosh --eval "db.getSiblingDB('dbcostops').createCollection('init')"
