該命令用於列舉本地的鏡像，其中還有本地命令的一些操作有如下，都是用來在本地做處理使用的
用法：
Usage: docker images [OPTIONS] [REPOSITORY[:TAG]]
List images
Options:
-a, --all Show all images (default hides intermediate images)
--digests Show digests
-f, --filter filter Filter output based on conditions provided
--format string Pretty-print images using a Go template
--no-trunc Don't truncate output
-q, --quiet Only show numeric IDs
示例：
docker images java
直接展示了repository爲java的鏡像
docker images -a
展示本地的所有鏡像，默認隱藏中間的鏡像
zhouzhenyong@shizi-2 ~/tem> docker images -a

docker images -f xxxx
查看對應的過濾條件
這個過濾標籤的格式是 “key=value”，如果有多個條件，則使用這種 --filter “key1=value” --filter “key2=value”
比如：過濾沒有打標籤的鏡像
docker images -f “dangling=true”
zhouzhenyong@shizi-2 ~/tem> docker images -f "dangling=true"

當前支持的過濾配置的key爲
- dangling：顯示標記爲空的鏡像，值只有true和false
- label：這個是根據標籤進行過濾，其中lable的值，是docker在編譯的時候配置的或者在Dockerfile中配置的
- before：這個是根據時間來進行過濾，其中before的value表示某個鏡像構建時間之前的鏡像列表
- since：跟before正好相反，表示的是在某個鏡像構建之後構建的鏡像
- reference：這個是添加正則進行匹配
docker images -f “dangling=true”
表示清理當前repo:tag爲的鏡像。在對應的鏡像repo:tag構建新的鏡像的時候，舊的鏡像就會從repo:tag中移走，進而成爲，這個時候，我們就可以對這些進行清理
docker rmi $(docker images -f “dangling=true” -q)
docker images -f “before=mysql”
表示在mysql:latest之前的構建的鏡像
zhouzhenyong@shizi-2 ~> docker images -f "before=mysql"
Error response from daemon: No such image: mysql:latest
zhouzhenyong@shizi-2 ~> docker images -f "before=mysql:8.0.20"

docker images --format
這個是進行對展示的進行格式化話展示
| Placeholder | Description |
|---|---|
.ID |
Image ID |
.Repository |
Image repository |
.Tag |
Image tag |
.Digest |
Image digest |
.CreatedSince |
Elapsed time since the image was created |
.CreatedAt |
Time when the image was created |
.Size |
Image disk size |
zhouzhenyong@shizi-2 ~> docker images --format "{{.ID}}\t{{.Repository}}"
