1：docker的默认存放位置：
$ sudo su
# cd /var/lib/docker # ls -F containers/ graph/ repositories volumes/ 2：把docker容器中的信息挂载到宿主机上指定的目录：
我在项目中用到需要时，将logback的日志在容器中挂载到宿主机上，
docker run -p 9005:9000 -it -v /home/docker/forecast/user/log:/var/log/forecast forecast/forecast.user.login /bin/bash
<configuration> <property name="APP_NAME" value="forecast.user.login" /> <property name="LOG_PATH" value="/var/log/forecast" /> <conversionRule conversionWord="coloredLevel" converterClass="play.api.libs.logback.ColoredLevel" /> <appender name="FILE" class="ch.qos.logback.core.FileAppender"> <file>${LOG_PATH}/${APP_NAME}.log</file> <encoder> <pattern>%date [%level] from %logger in %thread - %message%n%xException</pattern> </encoder>
$docker ps | less -S
[root@dpydalapp02 Downloads]# docker inspect dc617832a4df
