AWS AppConfig Dynamic Configuration System

🚀 Project Overview

This project demonstrates a cloud-native approach to managing application configurations and feature flags using AWS AppConfig and AWS CloudShell. I built a centralized system that allows for real-time updates to application settings without requiring code redeployments or service restarts.

🛠️ Key Features

• Centralized Configuration: Hosted application settings in the AWS AppConfig Hosted Store for a single source of truth.
• Automated Deployments: Developed a Bash CI/CD-lite script (deploy_config.sh) to automate the creation of configuration versions and trigger deployment strategies via the AWS CLI.
• Secure Version Control: Integrated with GitHub using Personal Access Tokens (PAT) and managed remote repository provisioning via the GitHub REST API.
• Zero-Downtime Updates: Enabled runtime configuration changes, significantly reducing the risk of deployment-related outages.

🛡️ Troubleshooting & Technical Challenges

During the integration phase, I resolved a critical Git metadata mismatch where the local environment was incorrectly targeting the base domain instead of the specific repository endpoint. I successfully debugged this by:

1. Auditing remote origins with git remote -v.
2. Validating the repository state using curl and the GitHub REST API.
3. Implementing an authenticated URL push to bypass local configuration drift and successfully sync over 3,000 objects.

🏗️ Technical Stack

• Cloud Platform: AWS (AppConfig, Systems Manager, CloudShell)
• Version Control: Git & GitHub
• Scripting: Bash / Linux CLI
• API Integration: GitHub REST API (cURL)
