Question

从haproxy构建haproxy容器：1.5-alpine

（https://github.com/docker-library/haproxy/blob/1848d2933afbefd0e0a068dc7b5a753ab7842e6c/1.5/alpine/Dockerfile）

haproxy容器开始正常但我如何才能实现详细的haproxy日志记录并将其指向stdout。

我的haproxy配置是

global
     log /dev/log  local0
    # log /dev/log  local1 notice
    # chroot /var/lib/haproxy
    # stats socket /run/haproxy/admin.sock mode 660 level admin
    stats timeout 30s
    user haproxy
    group haproxy
    daemon

    tune.ssl.default-dh-param 2048
    # Default SSL material locations
    #ca-base /etc/ssl/certs
    #crt-base /etc/ssl/private

    ssl-default-bind-options no-sslv3
    ssl-default-bind-ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-DSS-AES128-GCM
enter code here

defaults
    log global
    mode  http
    option  httplog
    option  dontlognull

    # fixed configuration by Benson
    option  http-keep-alive
    timeout http-keep-alive 5m
    timeout http-request 5s
    timeout connect 300s
    timeout client  300s
    timeout server  300s
    timeout check   300s

    #old configurations causing connection timeouts
    #timeout connect 5000
    #timeout client  50000
    #timeout server  50000

    errorfile 400 /usr/local/etc/haproxy/errors/400.http
    errorfile 403 /usr/local/etc/haproxy/errors/403.http
    errorfile 408 /usr/local/etc/haproxy/errors/408.http
    errorfile 500 /usr/local/etc/haproxy/errors/500.http
    errorfile 502 /usr/local/etc/haproxy/errors/502.http
    errorfile 503 /usr/local/etc/haproxy/errors/503.http
    errorfile 504 /usr/local/etc/haproxy/errors/504.http
    balance roundrobin
    option httpchk

我尝试了通过docker entrypoint.sh

中的以下命令将日志定向到stdout的选项

“/ bin / sh -c / sbin / syslogd -O / dev / stdout”

#!/bin/sh
set -e

# first arg is `-f` or `--some-option`
if [ "${1#-}" != "$1" ]; then
        set -- haproxy "$@"
fi

if [ "$1" = 'haproxy' ]; then
        # if the user wants "haproxy", let's use "haproxy-systemd-wrapper" instead so we can have proper reloadability implemented by upstream
        /bin/sh -c /sbin/syslogd -O /dev/stdout
        shift # "haproxy"
        set -- "$(which haproxy-systemd-wrapper)" -p /run/haproxy.pid "$@"
fi

exec "$@"

然而，当我通过haproxy浏览应用程序时，没有日志被注册，尽管它可以正常运行。

我想知道如何在alpine haproxy容器中通过haproxy获取详细的日志记录

您需要将/ dev / log从主机传递到容器中，然后从主机端读取您的日志！ haproxy的作者反对登录到stdout（出于性能原因），所以除了我所描述的（或在pod中的另一个容器中运行syslog守护进程）之外，你无能为力。
