示例
- 删除多个tag后在删除镜像 ``` $ docker images REPOSITORY TAG IMAGE ID CREATED SIZE test1 latest fd484f19954f 23 seconds ago 7 B (virtual 4.964 MB) test latest fd484f19954f 23 seconds ago 7 B (virtual 4.964 MB) test2 latest fd484f19954f 23 seconds ago 7 B (virtual 4.964 MB)
$ docker rmi fd484f19954f Error: Conflict, cannot delete image fd484f19954f because it is tagged in multiple repositories, use -f to force 2013/12/11 05:47:16 Error: failed to remove one or more images
$ docker rmi test1:latest Untagged: test1:latest
$ docker rmi test2:latest Untagged: test2:latest
$ docker images REPOSITORY TAG IMAGE ID CREATED SIZE test latest fd484f19954f 23 seconds ago 7 B (virtual 4.964 MB)
$ docker rmi test:latest Untagged: test:latest Deleted: fd484f19954f4920da7ff372b5067f5b7ddb2fd3830cecd17b96ea9e286ba5b8
- 强制删除镜像
如果使用该 `-f` 标志并指定镜像的短ID或长ID，则此命令删除所有与指定ID匹配的镜像tag。$ docker images
REPOSITORY TAG IMAGE ID CREATED SIZE test1 latest fd484f19954f 23 seconds ago 7 B (virtual 4.964 MB) test latest fd484f19954f 23 seconds ago 7 B (virtual 4.964 MB) test2 latest fd484f19954f 23 seconds ago 7 B (virtual 4.964 MB)
$ docker rmi -f fd484f19954f
Untagged: test1:latest Untagged: test:latest Untagged: test2:latest Deleted: fd484f19954f4920da7ff372b5067f5b7ddb2fd3830cecd17b96ea9e286ba5b8
