过滤标志--filter，格式为key=value。如果超过一个过滤，那么就传递多个标志 如–filter “foo=bar” –filter “bif=baz”
目前支持的过滤有：
-
dangling [布尔值 true 或 false]
-
label (label = 或 label==)
-
before ([:], or ) – 过滤出指定镜像之前的镜像
-
since ([:], or ) – 过滤出指定镜像之后的镜像
示例：
docker images –filter “dangling=true”：列出无 tag 镜像
[root@master core]$docker images --filter "dangling=true"
REPOSITORY TAG IMAGE ID CREATED SIZE
<none> <none> db4183094a81 About an hour ago 979MB
docker images –filter “before=docker.io/nginx:1.14″：列出 docker.io/nginx:1.14 之前的镜像
[root@moban ~]$docker images --filter "before=docker.io/nginx:1.14"
REPOSITORY TAG IMAGE ID CREATED SIZE

docker images –filter “since=docker.io/busybox”：列出对应镜像之后（指生成时间）的镜像
[root@moban ~]$docker images --filter "since=docker.io/busybox"
REPOSITORY TAG IMAGE ID CREATED SIZE

花式删除
以上所有操作，都可以基于查询，进行批量删除的操作，删除的方式有二：
docker rmi $(docker images –filter “since=docker.io/busybox”)
另一花查
--format 选项使用 Go 模板打印出指定格式的列表
Go 模板的有效占位符如下所示：
-
.ID – 镜像 ID
-
.Repository – 镜像存储库名称
-
.Tag – 镜像 tag
-
.Digest – 镜像 digest
-
.CreatedSince – 从镜像创建到现在过去的时间
-
.CreatedAt – 镜像创建的时间
-
.Size – 镜像硬盘占用大小
当使用–format 选项时，images 命令输出模板声明的完全相同的数据，或者使用 table 指令，将包括列标题。
如下显示无列标题的数据：
[root@moban ~]$docker images --format "{{.ID}}: {{.Repository}}"
5f2d4477b7ea: docker.io/nginx
e81eb098537d: docker.io/nginx
e81eb098537d: docker.io/nginx

2dbf82c07ebe: idocker.io/eryajf/jenkins
59788edf1f3e: docker.io/busybox
d23bdf5b1b1b: docker.io/java
显示带列标题的数据：
[root@moban ~]$docker images --format "table {{.ID}}\t{{.Repository}}\t{{.Tag}}"
