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.

### Listing 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 this command :
$ 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:
$ 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.
$ docker images java:0
REPOSITORY TAG IMAGE ID CREATED SIZE

## Listing image 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:
$ 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.
## Filtering
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>`) - filters images created before given id or references
* since (`<image-name>[:<tag>]`, `<image id>` or `<image@digest>`) - filters images created since given id or references
##### Untagged images (dangling)
$ 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.
Ready for use by `docker rmi ...`, like:
$ docker rmi $(docker images -f "dangling=true" -q)
8abc22fbb042
48e5f45168b9
bf747efa0e2f
980fe10e5736
dea752e4e117
511136ea3c5a
NOTE: Docker will warn you if any containers exist that are using these untagged images.
##### Labeled images
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.
$ 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.
$ 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.
$ docker images --filter "label=com.example.version=0.1"
REPOSITORY TAG IMAGE ID CREATED SIZE
#### Before
The `before` filter shows only images created before the image with
given id or reference. For example, having these images:
$ 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:
$ 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
#### Since
The `since` filter shows only images created after the image with
given id or reference. For example, having these images:
$ 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 `since` would give:
$ 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
## Formatting
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:
$ docker images --format "{{.ID}}: {{.Repository}}"
77af4d6b9913: <none>
b6fa739cedf5: committ
78a85c484f71: <none>
30557a29d5ab: docker

746b819f315e: postgres
746b819f315e: postgres
746b819f315e: postgres
To list all images with their repository and tag in a table format you
can use:
$ docker images --format "table {{.ID}}\t{{.Repository}}\t{{.Tag}}"
