我在docker容器中运行rsyslog以将UDP消息发送到logstash。
当我登录docker容器时，输入：
service rsyslog status
所示：
rsyslogd is not running ... failed!
但是，当我在容器中时，如果我输入：
service rsyslog start
它完美启动，没有任何错误，也没有真正的迹象表明它在开始时失败了
我无法弄清楚为什么会失败!!!!
*除了允许imfile的模块外，尚未修改rsyslog conf文件。 rsyslog.conf如下：
# /etc/rsyslog.conf Configuration file for rsyslog.

这是我在docker容器（centos7）中的rsyslog.conf：
$> cat /etc/rsyslog.conf |grep -vE '^$|^#'
$ModLoad imuxsock # provides support for local system logging (e.g. via logger command)
$WorkDirectory /var/lib/rsyslog
$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat
$IncludeConfig /etc/rsyslog.d/*.conf
$OmitLocalLogging off
*.info;mail.none;authpriv.none;cron.none /var/log/messages
authpriv.* /var/log/secure
mail.* -/var/log/maillog
cron.* /var/log/cron
*.emerg :omusrmsg:*
uucp,news.crit /var/log/spooler
local7.* /var/log/boot.log
我也更改了/etc/rsyslog.d/listen.conf
#$SystemLogSocketName /run/systemd/journal/syslog
然后
$> rsyslogd -n

我们在CentOS 7.3.1611上创建的Docker 17.03.2-ce映像上遇到了相同的问题。解决方案是根据this文档验证/etc/rsyslog.conf。基本上，在/etc/rsyslog.conf中：
最后，请注意，运行rsyslogd或其他任何操作都是由正在容器内运行的程序负责的。它不会自动启动。
