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.

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
REPOSITORYbut 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

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:
$ 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 (--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>orlabel=<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)
$ 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

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 ...:
$ 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.
$ 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
Filter images by time
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
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
Filter images by reference
The reference filter shows only images whose reference matches
the specified pattern.
$ 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:
$ 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:
$ 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
Format the output
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
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:
$ 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:
$ docker images --format json
