docker inspect
命令用于获取 Docker 对象（容器、镜像、卷、网络等）的详细信息，同时返回 JSON 格式的详细信息，可以帮助用户了解对象的配置和状态。
语法
docker inspect [OPTIONS] NAME|ID [NAME|ID...]
OPTIONS 说明：
**-f, --format**: 使用 Go 模板语法格式化输出。**--type**: 返回指定类型的对象信息（可选类型：container、image、network、volume）。
实例
1、检查容器
docker inspect my_container返回 my_container 容器的详细信息。
2、检查镜像
docker inspect my_image返回 my_image 镜像的详细信息。
3、检查卷
docker inspect my_volume返回 my_volume 卷的详细信息。
4、检查网络
docker inspect my_network返回 my_network 网络的详细信息。
5、格式化输出
docker inspect --format '{{ .State.Running }}' my_container返回 my_container 容器的运行状态，格式化输出为布尔值。
6、检查多个对象
docker inspect my_container my_image返回 my_container 容器和 my_image 镜像的详细信息。
实例输出
容器信息：
docker inspect my_container
输出：
