Configs do servidor de back -end:

 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
    },
