/var/log/messages 服务信息日志(记录linux操作系统常见的服务信息和错误信息)
/var/log/secure 系统的登陆日志(记录用户和工作组的变化情况,是系统安全日志，用户的认证登陆情况
/var/log/maillog 邮件日志
/var/log/cron 定时任务
/var/log/boot.log 系统启动日志

发现/var/log/messages有几个G的日志。查看日志内容发现rsyslog把Journal的log都进行的输出和汇总。
当容器越多是，log也就会也多，内存占用也就越多。

消减输出的日志，将log级别定义为err级别

修改rsyslogd配置文件/etc/rsyslog.conf

*.err;mail.none;authpriv.none;cron.none /var/log/messages

重启服务

systemctl daemon-reload
systemctl restart rsyslog
