📈 Development & Deployment

AWS Setup (One-time)

Create AWS Account and get access keys
Add GitHub Secrets:
- Go to repo → Settings → Secrets → Actions
- Add AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY
Push to main - infrastructure deploys automatically!

Environment Configuration

# .env file (automatically configured on EC2)
DATABASE_URL=postgresql://user:pass@localhost/sprintsync
JWT_SECRET=your-secret-key
OPENAI_API_KEY=your-openai-key
ENVIRONMENT=production

Fully Automated AWS Deployment

SprintSync features complete infrastructure automation - no manual setup required!

🚀 What happens automatically:

EC2 Instance Creation: Automatically provisions t3.small instance
Security Groups: Sets up HTTP/HTTPS/SSH access rules
Docker Installation: Installs and configures Docker + Docker Compose
Application Deployment: Builds and deploys your app
Health Checks: Verifies deployment success
Infrastructure Cleanup: Optional teardown of all resources

Required GitHub Secrets (Only 2!):

AWS_ACCESS_KEY_ID: Your AWS access key
AWS_SECRET_ACCESS_KEY: Your AWS secret key
AWS_EC2_PRIVATE_KEY: (Optional) Private key content if you have existing key pair

Deployment Cost: ~$15/month for t3.small instance (perfect for evaluation)
