How to use redis by docker compose deploy

[seepine]

I found redis service in docker-compose.yml, but i cannot found how to set like REDIS_URL in rustfs service

services:
  # RustFS main service
  rustfs:
    image: rustfs/rustfs:latest
    restart: always
    ports:
      - "9000:9000" # S3 API port
      - "39001:9001" # Console port
    environment:
      - RUSTFS_VOLUMES=/data/rustfs{0...3}  # Define 4 storage volumes
      - RUSTFS_ADDRESS=0.0.0.0:9000
      - RUSTFS_CONSOLE_ADDRESS=0.0.0.0:9001
      - RUSTFS_CONSOLE_ENABLE=true
      - RUSTFS_EXTERNAL_ADDRESS=:9000  # Same as internal since no port mapping
      - RUSTFS_CORS_ALLOWED_ORIGINS=*
      - RUSTFS_CONSOLE_CORS_ALLOWED_ORIGINS=*
      - RUSTFS_ACCESS_KEY=rustfsadmin
      - RUSTFS_SECRET_KEY=rustfsadmin
      # like this ?
      - REDIS_URL=rustfs-redis:6379
    volumes:
      - rustfs_data:/data
      - rustfs_logs:/app/logs
    security_opt:
      - "no-new-privileges:true"
    networks:
      - rustfs-network
    healthcheck:
      test:
        [
          "CMD",
          "sh", "-c",
          "curl -f http://localhost:9000/health && curl -f http://localhost:9001/rustfs/console/health"
        ]
      interval: 30s
      timeout: 10s
      retries: 3
      start_period: 20s

  # i change redis service host
  rustfs-redis:
    image: redis:7-alpine
    restart: always
    volumes:
      - redis_data:/data
    networks:
      - rustfs-network

networks:
  rustfs-network:

@seepine Already confirmed, redis part is useless, will delete the content later. So please ignore it.
