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.
Filters
Filters the output based on these conditions:
- dangling=(true|false) - find unused images
- label= or label==
- before=([:tag]||image@digest)
- since=([:tag]||image@digest)
- reference=(pattern of an image reference)
Format
Format the output using the given 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
EXAMPLES
Listing the images
To list the images in a local repository (not the registry) run:
docker image ls
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 image ls 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 image ls command lists all images in the
given repository.
docker image ls java
The [REPOSITORY[:TAG]] value must be an "exact match". This means that, for example,
docker image ls 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 image ls java:8
To get a verbose list of images which contains all the intermediate images used in builds use -a:
docker image ls -a
Previously, the docker image ls 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 images in a desired format
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. You can use special characters like \t for
inserting tab spacing between columns. The json directive outputs objects
in JSON format.
The following example uses a template without headers and outputs the ID and Repository entries separated by a colon for all images:
docker image ls --format "{{.ID}}: {{.Repository}}"
77af4d6b9913: <none>
b6fa739cedf5: committ
78a85c484bad: ipbabble
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 image ls --format "table {{.ID}}\t{{.Repository}}\t{{.Tag}}"
IMAGE ID REPOSITORY TAG
77af4d6b9913 <none> <none>
b6fa739cedf5 committ latest
78a85c484bad ipbabble <none>
30557a29d5ab docker latest
5ed6274db6ce <none> <none>
746b819f315e postgres 9
746b819f315e postgres 9.3
746b819f315e postgres 9.3.5
746b819f315e postgres latest
Valid template placeholders are listed above.
To list all images in JSON format you can use:
docker image ls --format json
