erros de configuração do haproxy

Question

Aqui está minha configuração

global
        log /dev/log   local0
        log 127.0.0.1   local1 notice
        maxconn 4096
        user haproxy
        group haproxy
        daemon

defaults
        log     global
        mode    http
        option  httplog
        option  dontlognull
        retries 3
        option redispatch
        maxconn 2000
        contimeout     5000
        clitimeout     50000
        srvtimeout     50000

listen webfarm 0.0.0.0:80
    mode http
    stats enable
    stats uri /haproxy?stats
    balance roundrobin
    option httpclose
    option forwardfor
    server apache 192.168.1.10:8001 weight 1  maxconn 512 check

Após a configuração, reiniciei o serviço haproxy, que recebi a seguinte mensagem

root@d32b2eb97bf0:/# service haproxy start

Eu fiz as etapas acima no contêiner docker. Como reslover ??

Obrigado.

A sintaxe foi alterada na versão recente do HAProxy. Eu tive esse problema na versão 1.6.5:

Alterar: listen webfarm 0.0.0.0:80

Para:

listen webfarm

bind 0.0.0.0:80
