This project demonstrates the integration of Envoy Proxy with the Go-Control-Plane to dynamically manage configurations, particularly for a Redis cluster. The focus is on implementing TCP health checks to monitor the status of Redis nodes and update Envoy's configuration in response to changes in the Redis cluster.

Envoy is used as a front proxy in this setup, routing traffic to a Redis cluster. The Go-Control-Plane serves as an xDS server to dynamically update Envoy's configuration, especially for handling changes in the Redis master node.

• Dynamic Redis Cluster Management: Automatically updates Envoy's configuration when the Redis master node changes.
• TCP Health Checks: Implements health checks for Redis nodes to monitor their status.
• Efficient Configuration Updates: Utilizes Envoy's xDS APIs for seamless and efficient configuration updates without restarting Envoy.

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

• Docker
• Golang (for running the Go-Control-Plane)
• An Envoy Proxy setup

1. Build and run the containers (including Envoy, Redis, and the Go-Control-Plane):

   docker-compose up --build

• Envoy Configuration: Configured to communicate with the Go-Control-Plane for dynamic updates.
• Go-Control-Plane: Implements the xDS protocol to manage Envoy's configuration, particularly for updating Redis cluster information and health checks.

The health checks for Redis are implemented using TCP checks. The Go-Control-Plane sends PING commands to the Redis nodes and expects a PONG response to confirm their status.

Once the setup is running, Envoy will dynamically adjust its routing based on the health and status of the Redis nodes as provided by the Go-Control-Plane.
