- 查看明细
命令：docker inspect [OPTIONS] CONTAINER|IMAGE [CONTAINER|IMAGE...]
参数：-f, --format="" Format the output using the given go template.
例子：
[root@localhost ~]# docker inspect f01c1b138488
- 删除
命令：docker rmi [OPTIONS] IMAGE [IMAGE...]
参数：
-f, --force=false Force removal of the image
--no-prune=false Do not delete untagged parents
例子：
[root@localhost ~]# docker rmi 26c
Error response from daemon: Conflict, cannot delete 26c0c52dc79a because the container 002ca178e599 is using it, use -f to force
上面出错的原因是因为该镜像正在被002ca178e599的容器使用，所以不能删除，所以首先需要使用docker rm删除容器，然后再删除，相关的AUFS文件也会被删除
[root@localhost ~]# docker rm 002

[root@localhost ~]# docker rmi 26c
