我的目标@H_502_2@

我在主机中运行着几个不同的容器.它们都与彼此的/ dev / log套接字共享一个卷.主机将这些日志转发到中央日志服务器.其他所有容器日志都显示在主机的/ var / log / messages中.其他容器是python程序,它允许日志记录直接附加到/ dev / log unix域套接字.@H_502_2@

基本配置@H_502_2@

我有一个从jar文件运行scala应用程序的docker容器. / dev / log套接字在主机和容器之间作为卷共享.该应用程序的log4j.properties文件对我来说似乎不错,并且设置如下：@H_502_2@

@H_502_2@

# Root logger option
log4j.rootLogger=INFO,file,stdout,SYSLOG

# Direct log messages to a log file
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=log/associationRules.log
log4j.appender.file.MaxFileSize=10MB
log4j.appender.file.MaxBackupIndex=10
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} [%c{1}:%L] %-5p <%X{jobID}> %m%n

# Direct log messages to stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} [%c{1}:%L] %-5p <%X{jobID}> %m%n

# Log to syslog
log4j.appender.SYSLOG=org.apache.log4j.net.SyslogAppender
log4j.appender.SYSLOG.syslogHost=localhost
log4j.appender.SYSLOG.layout=org.apache.log4j.PatternLayout
log4j.appender.SYSLOG.layout.conversionPattern=%d{yyyy-MM-dd HH:mm:ss} [%c{1}:%L] %-5p <%X{jobID}> %m%n
log4j.appender.SYSLOG.Facility=LOCAL0
log4j.appender.SYSLOG.Threshold=debug
log4j.appender.SYSLOG.FacilityPrinting=true

标准输出和文件日志正确完成,但是SYSLOG似乎无法正常工作.日志显示在容器的/ var / log / syslog中,但不显示在主机的/ var / log / messages中.我以为SyslogAppender也会输出到/ dev / log,但似乎并没有这样做.@H_502_2@

额外细节@H_502_2@

这是我在容器的/ var / log / syslog中获得的输出.我看到imuxsock无法运行的一些问题,但我不明白日志如何存储在/ var / log / syslog上.最后两行来自应用程序,与stdout和文件附加程序一致@H_502_2@

容器的基本映像是ubuntu 14.04,安装了java.在dockerfile中,该容器映像的My CMD为：@H_502_2@

@H_502_2@

CMD sudo service rsyslog start; java -cp /root/AssociationRules.jar AssocApp

然后像这样启动容器：@H_502_2@

@H_502_2@

docker run -d -v /dev/log:/dev/log <IMAGE>
