Docker35- docker inspect 命令详解

如果你还想从头学起 Docker，可以看看这个系列的文章哦！

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

 

重点

-f 的使用场景更有实用性

 

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

 

获取容器的镜像名

root@PL-TEST:~# docker inspect -f "{{.Config.Image}}" p100_syslog
registry.cn-shenzhen.com/image/syslog:1.0

 

获取容器目录挂载信息

docker inspect --format={{json .Mounts}}" container

可以看到这种输出结果不太友好

 

美化输出结果

#使用python的json模块美化

docker inspect --format=" container | python -m json.tool

#使用jq美化

docker inspect --format=" container | jq

 

获取容器网络信息

#查看完整网络信息

docker inspect --format={{json .NetworkSettings}}" container | jq

#查看网络端口映射

docker inspect --format={{json .NetworkSettings.Ports}} jq

# 查看容器的网络ip、网关等信息

docker inspect --format={{json .NetworkSettings.Networks}}" container | jq

 

获取容器特定端口的映射信息

docker inspect --format={{(index (index .NetworkSettings.Ports "8787/tcp") 0).HostPort}}' $INSTANCE_ID

到时候改 8787 这个端口就行

 

获取容器的元数据

docker inspect tomcat7

 结果
