本文演示了如何使用Docker命令查看系统中镜像和容器的使用情况，包括`docker system df`来检查资源占用，以及如何删除镜像。在删除镜像时遇到了因容器正在使用而产生的冲突，通过添加`-f`参数强制删除解决了问题。此外，还展示了批量删除镜像的方法。

docker system df

查看docker使用情况

[root@localhost ~]# docker system df
TYPE            TOTAL     ACTIVE    SIZE      RECLAIMABLE
Images          3         1         182MB     182MB (99%)

[root@localhost ~]#

docker rmi hello-world

通过镜像名称从docker仓库中删除镜像

[root@localhost ~]# docker images
REPOSITORY    TAG       IMAGE ID       CREATED         SIZE
ubuntu        latest    27941809078c   4 weeks ago     77.8MB
hello-world   latest    feb5d9fea6a5   9 months ago    13.3kB
redis         6.0.8     16ecd2772934   20 months ago   104MB
[root@localhost ~]# docker rmi hello-world
Error response from daemon: conflict: unable to remove repository reference "hello-world" (must force) - container 11a256a8709f is using its referenced image feb5d9fea6a5

[root@localhost ~]# docker rmi -f feb5d9fea6a5
Untagged: hello-world:latest
Untagged: hello-world@sha256:13e367d31ae85359f42d637adf6da428f76d75dc9afeb3c21faea0d976f5c651

[root@localhost ~]#

报错了，但是可以通过-f 参数强制删除

docker rmi feb5d9fea6a5

通过镜像ID从docker仓库中删除镜像

[root@localhost ~]# docker images
REPOSITORY    TAG       IMAGE ID       CREATED         SIZE
