docker image ls

内容説明	List images
利用方法	`docker image ls [OPTIONS] [REPOSITORY[:TAG]]`
エイリアス	`docker image list` `docker images`

内容説明

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 the following 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> 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)

$ docker images --filter "dangling=true"

REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE

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 a 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

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 (--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:

$ 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
{"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"}
