# rmi
|
|

```markdown
|
|
Usage: docker rmi [OPTIONS] IMAGE [IMAGE...]
|
|
|
|
Remove one or more images
|
|
|
|
Options:
|
|
-f, --force Force removal of the image
|
|
--help Print usage
|
|
--no-prune Do not delete untagged parents
|
|
```
|
|
|
|
## Description
|
|
|
|
Removes (and un-tags) one or more images from the host node. If an image has
|
|
multiple tags, using this command with the tag as a parameter only removes the
|
|
tag. If the tag is the only one for the image, both the image and the tag are
|
|
removed.
|
|
|
|
This does not remove images from a registry. You cannot remove an image of a
|
|
running container unless you use the `-f` option. To see all images on a host
|
|
use the [`docker image ls`](images.md) command.
|
|
|
|
## Examples
|
|
|
|
You can remove an image using its short or long ID, its tag, or its digest. If
|
|
an image has one or more tags referencing it, you must remove all of them before
|
|
the image is removed. Digest references are removed automatically when an image
|
|
is removed by tag.
|
|
|
|
```bash
|
|
$ docker images

|
If you use the `-f` flag and specify the image's short or long ID, then this
|
|
command untags and removes all images that match the specified ID.

```bash

$ docker images

An image pulled by digest has no tag associated with it:

|
|
|
```bash
|
|
$ docker images --digests
