docker 镜像删除
| Description | Remove one or more images |
|---|---|
| Usage | docker image rm [OPTIONS] IMAGE [IMAGE...] |
| Aliases | docker image remove
docker rmi |
描述
从主机节点移除（并取消标记）一个或多个图像。如果图像有多个标记，使用此命令并指定标记作为参数只会移除该标记。如果该标记是图像的唯一标记，则图像和标记都会被移除。
这不会从注册表中删除镜像。除非使用-f选项，否则无法删除正在运行的容器的镜像。要查看主机上的所有镜像，请使用docker image ls命令。
选项
| Option | Default | Description |
|---|---|---|
-f, --force | Force removal of the image | |
--no-prune | Do not delete untagged parents |
示例
您可以使用图像的短ID或长ID、标签或摘要来删除图像。如果图像有一个或多个标签引用它，您必须在删除图像之前删除所有这些标签。当通过标签删除图像时，摘要引用会自动删除。

如果您使用-f标志并指定图像的短ID或长ID，则此命令将取消标记并删除所有与指定ID匹配的图像。
