作用

获取容器/镜像的元数据（JSON格式）

语法格式

docker inspect [OPTIONS] NAME|ID [NAME|ID...]

options 说明

option	说明
-f	指定返回值的模板文件
-s	如果类型为容器，则显示文件总大小
--type	返回指定类型的JSON

实际栗子

获取容器 IP

docker inspect --format='{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' $CONTAINER_ID

简单版本

docker inspect tomcat7 | grep IPAddress

就是内容会多了点，但有输出关键信息就行

获取容器 MAC 地址

docker inspect --format='{{range .NetworkSettings.Networks}}{{.MacAddress}}{{end}}' $CONTAINER_ID

简单版本

docker inspect tomcat7 | grep MacAddress

万物皆可 grep 哈哈哈

获取容器日志路径

docker inspect --format='{{.LogPath}}' $CONTAINER_ID

获取容器的元数据

docker inspect tomcat7

结果
