QuickStart

$ git clone https://github.com/Triple-Z/dlb-demo
$ cd dlb-demo/
$ docker-compose up

그런 다음 http : // localhost : 8888을 방문하면 계속해서 응답 내용 번호가 항상 변경되고 있음을 알게됩니다.

또는 for i in {1..10} ; do curl http://localhost:8888 ; done 대신 for i in {1..10} ; do curl http://localhost:8888 ; done .

예제 결과

백엔드 서버 구성 :

 servers = {
    {
        host = " 172.28.0.101 " ,
        port = 80 ,
        weight = 5 , -- backend 1
    },
    {
        host = " 172.28.0.102 " ,
        port = 80 ,
        weight = 3 , -- backend 2
    },
    {
        host = " 172.28.0.103 " ,
        port = 80 ,
        weight = 2 , -- backend 3
    },
}

결과:

 # Round-robin (rr)
$ for i in {1..10} ; do curl http://localhost:8888 ; done
response from backend 1
response from backend 2
response from backend 3
response from backend 1
response from backend 2
response from backend 3

# Weighted round-robin (wrr)
$ for i in {1..10} ; do curl http://localhost:8888 ; done
