Dynamic Load Balancer

• Dynamic NGINX configuration stored in redis
• Still heavily in development
• Inspired by the hipache-nginx project
• Uses the openresty version of nginx inorder to use lua scripts for connecting nginx to redis

Usage

1. Run docker-compose up
2. Launch redis-commander in browser at http://localhost:8081 or use redis-cli
3. Run the following redis commands:
   • rpush frontend:9000 http://mb1:2525
   • rpush frontend:9000 http://mb2:2525
   • rpush frontend:9001 http://mb1:2525
4. Now curl http://localhost:9000 should randomly go to either mb1 or mb2. And curl http://localhost:9001 should always go to mb3.

TODOs

• Benchmarks vs a oob nginx instance
• Observability
• Support for HTTPS - DONE
• Support for TCP
• Distributed Support - Kubernetes poc
• Log Forwarding
