【问题描述】:
我目前配置了 deamon docker 的 logging_driver 以写入 journald,以便使用来自 kubernetes pod 的 fluentd 解析它们。在节点方面,我有一个使用以下默认配置运行的 rsyslog:
# Default rules for rsyslog.
#
# For more information see rsyslog.conf(5) and /etc/rsyslog.conf
#
# First some standard log files. Log by facility.
#
auth,authpriv.* /var/log/auth.log
*.*;auth,authpriv.none -/var/log/syslog
#cron.* /var/log/cron.log
#daemon.* -/var/log/daemon.log
kern.* -/var/log/kern.log
#lpr.* -/var/log/lpr.log
mail.* -/var/log/mail.log
#user.* -/var/log/user.log
#
# Logging for the mail system. Split it up so that
# it is easy to write scripts to parse these files.
#
#mail.info -/var/log/mail.info
#mail.warn -/var/log/mail.warn
mail.err /var/log/mail.err
#
# Logging for INN news system.
#
news.crit /var/log/news/news.crit
news.err /var/log/news/news.err
news.notice -/var/log/news/news.notice
#
# Some "catch-all" log files.
#
#*.=debug;\
# auth,authpriv.none;\
# news.none;mail.none -/var/log/debug
#*.=info;*.=notice;*.=warn;\
# auth,authpriv.none;\
# cron,daemon.none;\
# mail,news.none -/var/log/messages
#
# Emergencies are sent to everybody logged in.
#
*.emerg :omusrmsg:*
#
# I like to have messages displayed on the console, but only on a virtual
# console I usually leave idle.
#
#daemon,mail.*;\
# news.=crit;news.=err;news.=notice;\
# *.=debug;*.=info;\
# *.=notice;*.=warn /dev/tty8
# The named pipe /dev/xconsole is for the `xconsole' utility. To use it,
# you must invoke `xconsole' with the `-file' option:
#
# $ xconsole -file /dev/xconsole [...]
#
# NOTE: adjust the list below, or you'll go crazy if you have a reasonably
# busy site..
#
daemon.*;mail.*;\
news.err;\
*.=debug;*.=info;\
*.=notice;*.=warn |/dev/xconsole
发生的情况是,所有进入日志的日志记录也都放在了 syslog 和 kern.log 中。 由于大量容器在 kubernetes 节点和控制平面内运行,我想最小化几个位置的指数日志记录,除了将它们放入日志之外,已经保存到 EFK 日志记录系统中。 有没有人遇到同样的问题?,我该如何避免这种情况?
【问题讨论】:
-
你能分享你的 Docker 守护进程的配置吗?
-
我使用 OPTIONS 将标志传递给启动包装器:
OPTIONS=" -H unix:///var/run/docker.sock --ip-forward=true --iptables=false --ip-masq=false --log-driver journald" -
您可以尝试更改
/etc/docker/daemon.json中的设置吗,就像在此说明中一样:docs.docker.com/config/containers/logging/json-file -
把日志驱动改成json-file,问题不存在了。不是正确的解决方案,但最终这是避免大量重复空间的解决方法。非常感谢@ArtemGolenyaev
