实际例子
获取容器 IP
获取容器 MAC 地址
获取容器日志路径
获取容器的元数据
获取镜像的元数据
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 |
实际例子
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
docker inspect tomcat7 | grep MacAddress
万物皆可 grep
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
