RDS Forwarder - EKS to Private RDS Connection
Overview
This deployment creates a bridge to access private RDS MySQL database through EKS cluster.
Quick Start
1. Deploy the forwarder: kubectl apply -f rds-forwarder.yaml
2. Start port forwarding: kubectl port-forward deployment/rds-forwarder-deployment 3307:3306
3. Connect locally: mysql -h 127.0.0.1 -P 3307 -u username -p database_name
Architecture
Local (3307) → kubectl port-forward → EKS Pod (3306) → Private RDS MySQL (3306)
