docker-images — List images

Synopsis

docker images [--help] [-a|--all] [--digests] [-f|--filter[=[]]] [--no-trunc] [-q|--quiet] [REPOSITORY[:TAG]]

Description

This command lists the images stored in the local Docker repository.

By default, intermediate images, used during builds, are not listed. Some of the output, e.g., image ID, is truncated, for space reasons. However the truncated image ID, and often the first few characters, are enough to be used in other Docker commands that use the image ID. The output includes repository, tag, image ID, date created and the virtual size.

The title REPOSITORY for the first title may seem confusing. It is essentially the image name. However, because you can tag a specific image, and multiple tags (image instances) can be associated with a single name, the name is really a repository for all tagged images of the same name. For example consider an image called fedora. It may be tagged with 18, 19, or 20, etc. to manage different versions.

Options

-a, --all=true|false
Show all images (by default filter out the intermediate image layers). The default is false.
--digests=true|false
Show image digests. The default is false.
-f, --filter=[]

Filters the output based on these conditions:
- dangling=(true|false) - finds unused images.
- label=<key> or label=<key>=<value>
- before=(<image-name>[:tag]|<image-id>| ⟨image@digest⟩)
- since=(<image-name>[:tag]|<image-id>| ⟨image@digest⟩)
--format="TEMPLATE"
Pretty-print containers using a Go template.
Valid placeholders:
.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.
--help
Print usage statement
--no-trunc=true|false
Don't truncate output. The default is false.
-q, --quiet=true|false
Only show numeric IDs. The default is false.

Listing the images

To list the images in a local repository (not the registry) run:

docker images

The list will contain the image repository name, a tag for the image, and an image ID, when it was created and its virtual size. Columns: REPOSITORY, TAG, IMAGE ID, CREATED, and SIZE.

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.

docker images java

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

To get a verbose list of images which contains all the intermediate images used in builds use -a:

docker images -a

Previously, the docker images command supported the --tree and --dot arguments, which displayed different visualizations of the image data. Docker core removed this functionality in the 1.7 version. If you liked this functionality, you can still find it in the third-party dockviz tool: ⟨https://github.com/justone/dockviz⟩.

Listing only the shortened image IDs

Listing just the shortened image IDs. This can be useful for some automated tools.

docker images -q
