The default `docker images` will show all top level
|
|
|
|
|
images, their repository and tags, and their virtual 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 `VIRTUAL 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 `VIRTUAL SIZE` listed only once.

### Listing 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 this command :
|
|
|
|
|
|
|
|
|
|
$ docker images java
|
|
|
|
|
REPOSITORY TAG IMAGE ID CREATED VIRTUAL 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 VIRTUAL SIZE
|
|
|
|
|
java 8 308e519aac60 6 days ago 824.5 MB
|
|
|
|
|
|
|
|
|
|
If nothing matches `REPOSITORY[:TAG]`, the list is empty.
|
|
|
|
|
|
|
|
|
|
$ docker images java:0
|

## Listing image 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 VIRTUAL SIZE

|
|
|
|
|
|
|
|
|
|
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
|
|
|
|
|
|
|
|
|
|
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>`)
|
|

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
|
2015-12-08 13:08:29 -05:00
|
|
|
`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.

Ready for use by `docker rmi ...`, like:
|
|

|
|

$ docker rmi $(docker images -f "dangling=true" -q)

##### Labeled images
|
|
|
|
|
|
|
|
|
|
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"
