## Description

The default `docker images` will show all top level
images, their repository and tags, and their size.

Docker images have intermediate layers that increase reusability,
decrease disk usage, and speed up `docker build` by
allowing each step to be cached. These intermediate layers are not shown
by default.

The `SIZE` is the cumulative space taken up by the image and all
its parent images. This is also the disk space used by the contents of the
Tar file created when you `docker save` an image.

An image will be listed more than once if it has multiple repository names
or tags. This single image (identifiable by its matching `IMAGE ID`)
uses up the `SIZE` listed only once.

## Examples

### List the most recently created images

```console
$ docker images

```

### List images by name and tag

The `docker images` command takes an optional `[REPOSITORY[:TAG]]` argument
that restricts the list to images that match the argument. If you specify
`REPOSITORY`but no `TAG`, the `docker images` command lists all images in the
given repository.

For example, to list all images in the `java` repository, run the following command:

```console
$ docker images java

REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
java                8                   308e519aac60        6 days ago          824.5 MB
java                7                   493d82594c15        3 months ago        656.3 MB
java                latest              2711b1d6f3aa        5 months ago        603.9 MB
```

The `[REPOSITORY[:TAG]]` value must be an exact match. This means that, for example,
`docker images jav` does not match the image `java`.

If both `REPOSITORY` and `TAG` are provided, only images matching that
repository and tag are listed.  To find all local images in the `java`
repository with tag `8` you can use:

```console
$ docker images java:8

REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
java                8                   308e519aac60        6 days ago          824.5 MB
```

If nothing matches `REPOSITORY[:TAG]`, the list is empty.

```console
$ docker images java:0

REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
```

### <a name="no-trunc"></a> List the full length image IDs (--no-trunc)

```console
$ docker images --no-trunc

REPOSITORY                    TAG                 IMAGE ID                                                                  CREATED             SIZE

```

### <a name="digests"></a> List image digests (--digests)

Images that use the v2 or later format have a content-addressable identifier
called a `digest`. As long as the input used to generate the image is
unchanged, the digest value is predictable. To list image digest values, use
the `--digests` flag:

```console
$ docker images --digests
REPOSITORY                         TAG                 DIGEST                                                                    IMAGE ID            CREATED             SIZE
localhost:5000/test/busybox        <none>              sha256:cbbf2f9a99b47fc460d422812b6a5adff7dfee951d8fa2e4a98caa0382cfbdbf   4986bf8c1536        9 weeks ago         2.43 MB
```

When pushing or pulling to a 2.0 registry, the `push` or `pull` command
output includes the image digest. You can `pull` using a digest value. You can
also reference by digest in `create`, `run`, and `rmi` commands, as well as the
`FROM` image reference in a Dockerfile.

### <a name="filter"></a> Filtering (--filter)

The filtering flag (`-f` or `--filter`) format is of "key=value". If there is more
than one filter, then pass multiple flags (e.g., `--filter "foo=bar" --filter "bif=baz"`).

The currently supported filters are:

* dangling (boolean - true or false)
* label (`label=<key>` or `label=<key>=<value>`)
* before (`<image-name>[:<tag>]`,  `<image id>` or `<image@digest>`) - filter images created before given id or references
* since (`<image-name>[:<tag>]`,  `<image id>` or `<image@digest>`) - filter images created since given id or references
* reference (pattern of an image reference) - filter images whose reference matches the specified pattern

#### Show untagged images (dangling)

```console
$ docker images --filter "dangling=true"

REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
<none>              <none>              8abc22fbb042        4 weeks ago         0 B
<none>              <none>              48e5f45168b9        4 weeks ago         2.489 MB
<none>              <none>              bf747efa0e2f        4 weeks ago         0 B
<none>              <none>              980fe10e5736        12 weeks ago        101.4 MB
<none>              <none>              dea752e4e117        12 weeks ago        101.4 MB
<none>              <none>              511136ea3c5a        8 months ago        0 B
```

This will display untagged images that are the leaves of the images tree (not
intermediary layers). These images occur when a new build of an image takes the
`repo:tag` away from the image ID, leaving it as `<none>:<none>` or untagged.
A warning will be issued if trying to remove an image when a container is presently
using it. By having this flag it allows for batch cleanup.

You can use this in conjunction with `docker rmi`:

```console
$ docker rmi $(docker images -f "dangling=true" -q)

8abc22fbb042
48e5f45168b9
bf747efa0e2f
980fe10e5736
dea752e4e117
511136ea3c5a
```

Docker warns you if any containers exist that are using these untagged images.


#### Show images with a given label

The `label` filter matches images based on the presence of a `label` alone or a `label` and a
value.

The following filter matches images with the `com.example.version` label regardless of its value.

```console
$ docker images --filter "label=com.example.version"

REPOSITORY          TAG                 IMAGE ID            CREATED              SIZE
match-me-1          latest              eeae25ada2aa        About a minute ago   188.3 MB
match-me-2          latest              dea752e4e117        About a minute ago   188.3 MB
```

The following filter matches images with the `com.example.version` label with the `1.0` value.

```console
$ docker images --filter "label=com.example.version=1.0"

REPOSITORY          TAG                 IMAGE ID            CREATED              SIZE
match-me            latest              511136ea3c5a        About a minute ago   188.3 MB
```

In this example, with the `0.1` value, it returns an empty set because no matches were found.

```console
$ docker images --filter "label=com.example.version=0.1"
REPOSITORY          TAG                 IMAGE ID            CREATED              SIZE
```

#### Filter images by time

The `before` filter shows only images created before the image with
a given ID or reference. For example, having these images:

```console
$ docker images

REPOSITORY          TAG                 IMAGE ID            CREATED              SIZE
image1              latest              eeae25ada2aa        4 minutes ago        188.3 MB
image2              latest              dea752e4e117        9 minutes ago        188.3 MB
image3              latest              511136ea3c5a        25 minutes ago       188.3 MB
```

Filtering with `before` would give:

```console
$ docker images --filter "before=image1"

REPOSITORY          TAG                 IMAGE ID            CREATED              SIZE
image2              latest              dea752e4e117        9 minutes ago        188.3 MB
image3              latest              511136ea3c5a        25 minutes ago       188.3 MB
```

Filtering with `since` would give:

```console
$ docker images --filter "since=image3"
REPOSITORY          TAG                 IMAGE ID            CREATED              SIZE
image1              latest              eeae25ada2aa        4 minutes ago        188.3 MB
image2              latest              dea752e4e117        9 minutes ago        188.3 MB
```

#### Filter images by reference

The `reference` filter shows only images whose reference matches
the specified pattern.

```console
$ docker images

REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
busybox             latest              e02e811dd08f        5 weeks ago         1.09 MB
busybox             uclibc              e02e811dd08f        5 weeks ago         1.09 MB
busybox             musl                733eb3059dce        5 weeks ago         1.21 MB
busybox             glibc               21c16b6787c6        5 weeks ago         4.19 MB
```

Filtering with `reference` would give:

```console
$ docker images --filter=reference='busy*:*libc'

REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
busybox             uclibc              e02e811dd08f        5 weeks ago         1.09 MB
busybox             glibc               21c16b6787c6        5 weeks ago         4.19 MB
```

Filtering with multiple `reference` would give, either match A or B:

```console
$ docker images --filter=reference='busy*:uclibc' --filter=reference='busy*:glibc'

REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
busybox             uclibc              e02e811dd08f        5 weeks ago         1.09 MB
busybox             glibc               21c16b6787c6        5 weeks ago         4.19 MB
```

### <a name="format"></a> Format the output (--format)

The formatting option (`--format`) will pretty print container output
using a Go template.

Valid placeholders for the Go template are listed below:

| 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                          |

When using the `--format` option, the `image` command will either
output the data exactly as the template declares or, when using the
`table` directive, will include column headers as well.

The following example uses a template without headers and outputs the
`ID` and `Repository` entries separated by a colon (`:`) for all images:

```console
$ docker images --format "{{.ID}}: {{.Repository}}"

77af4d6b9913: <none>
b6fa739cedf5: committ
78a85c484f71: <none>
30557a29d5ab: docker
5ed6274db6ce: <none>
746b819f315e: postgres
746b819f315e: postgres
746b819f315e: postgres
746b819f315e: postgres
```

To list all images with their repository and tag in a table format you
can use:

```console
$ docker images --format "table {{.ID}}\t{{.Repository}}\t{{.Tag}}"

IMAGE ID            REPOSITORY                TAG
77af4d6b9913        <none>                    <none>
b6fa739cedf5        committ                   latest
78a85c484f71        <none>                    <none>
30557a29d5ab        docker                    latest
5ed6274db6ce        <none>                    <none>
746b819f315e        postgres                  9
746b819f315e        postgres                  9.3
746b819f315e        postgres                  9.3.5
746b819f315e        postgres                  latest
```

To list all images in JSON format, use the `json` directive:

```console
$ docker images --format json
{"Containers":"N/A","CreatedAt":"2021-03-04 03:24:42 +0100 CET","CreatedSince":"5 days ago","Digest":"\u003cnone\u003e","ID":"4dd97cefde62","Repository":"ubuntu","SharedSize":"N/A","Size":"72.9MB","Tag":"latest","UniqueSize":"N/A","VirtualSize":"72.9MB"}
{"Containers":"N/A","CreatedAt":"2021-02-17 22:19:54 +0100 CET","CreatedSince":"2 weeks ago","Digest":"\u003cnone\u003e","ID":"28f6e2705743","Repository":"alpine","SharedSize":"N/A","Size":"5.61MB","Tag":"latest","UniqueSize":"N/A","VirtualSize":"5.613MB"}
```
