-#### Initialize Cluster
-```bash
-# Start Redis nodes
-docker-compose -f docker-compose-redis.yml up -d
-
-# Wait for nodes to start
-sleep 10
-
-# Create cluster
-docker exec -it lcbp3-redis-1 redis-cli --cluster create \
-  172.20.0.2:6379 \
-  172.20.0.3:6379 \
-  172.20.0.4:6379 \
-  --cluster-replicas 0
-
-# Verify cluster
-docker exec -it lcbp3-redis-1 redis-cli cluster info
-docker exec -it lcbp3-redis-1 redis-cli cluster nodes
-```
-
-#### Health Check Script
-```bash
-#!/bin/bash
-# scripts/check-redis-cluster.sh
-
-echo "🔍 Checking Redis Cluster Health..."
-
-for port in 6379 6380 6381; do
-  echo "\n📍 Node on port $port:"
