rlb

(R)ust(L)oad(B)alancer, simple reverse-proxy written to learn the language.

PoC ported from llb as a learning and comparative exercise, evaluation of Rust language and dabbling with a solid type-system.

Features:

• Basic healthcheck for backends
• Round-robin, hash-balancing, random-balancing, leasttraffic

To test it I run some local nginx on docker:

$ docker run --rm --name nginx-1 --publish 7892:80 nginx

$ docker run --rm --name nginx-2 --publish 9898:80 nginx

And run the load-balancer with config.yaml

listen_on: "127.0.0.1:6767"
backends:
    - "127.0.0.1:7892"
    - "127.0.0.1:9898"
probe_interval: 5000
balancing: round-robin
