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
|
|
`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 the following command:
|
|
|
|
```console
|
|
$ 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:
|
|
|
|
```console
|
|
$ 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.
|
|
|
|
```console
|
|
$ docker images java:0
|
|
|
|
REPOSITORY TAG IMAGE ID CREATED SIZE
|
|
```
|
|
|
|

|
|
|
|
### List image digests (--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:
|
|
|
|
```console
|
|
$ 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) {#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)
|
|
|
|
```console
|
|
$ 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.
|
|
|
|
You can use this in conjunction with `docker rmi`:
|
|
|
|
```console
|
|
$ 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.
|
|
|
|
```console
|
|
$ 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.
|
|
|
|
```console
|
|
$ 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.
|
|
|
|
```console
|
|
$ 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:
|
|
|
|
```console
|
|
$ 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:
|
|
|
|
```console
|
|
$ 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:
|
|
|
|
```console
|
|
$ 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.
|
|
|
|
```console
|
|
$ 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:
|
|
|
|
```console
|
|
$ 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:
|
|
|
|
```console
|
|
$ 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) {#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:
|
|
|
|
```console
|
|
$ docker images --format "{{.ID}}: {{.Repository}}"
|
|
|
|
77af4d6b9913: <none>
|
|
b6fa739cedf5: committ
|
|
78a85c484f71: <none>
|
|

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

|

|

|
|
746b819f315e postgres 9.3.5
|
|
746b819f315e postgres latest
|
|
```
|
|
|
|
To list all images in JSON format, use the `json` directive:
|
|
|
|
```console
|
|
$ 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"}
