images
Usage: hyper images [OPTIONS] [REPOSITORY[:TAG]]
List images
-a, --all=false Show all images (default hides intermediate images)
--digests=false Show digests
-f, --filter=[] Filter output based on conditions provided
--help=false Print usage
--no-trunc=false Don't truncate output
-q, --quiet=false Only show numeric IDsThe default hyper 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 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 hyper 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.

The hyper 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 hyper images command lists all images in the given repository.
For example, to list all images in the "java" repository, run this command :
$ hyper 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 MBThe [REPOSITORY[:TAG]] value must be an "exact match". This means that, for example, hyper 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:
$ hyper images java:8
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
java 8 308e519aac60 6 days ago 824.5 MBIf nothing matches REPOSITORY[:TAG], the list is empty.
$ hyper images java:0

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:
$ hyper images --digests
REPOSITORY TAG DIGEST IMAGE ID CREATED VIRTUAL SIZE
localhost:5000/test/busybox <none> sha256:cbbf2f9a99b47fc460d422812b6a5adff7dfee951d8fa2e4a98caa0382cfbdbf 4986bf8c1536 9 weeks ago 2.43 MBWhen 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>orlabel=<key>=<value>)
Untagged images (dangling)
$ hyper images --filter "dangling=true"

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.
Ready for use by hyper rmi ..., like:
$ hyper rmi $(hyper images -f "dangling=true" -q)

511136ea3c5aNOTE: Hyper will warn you if any containers exist that are using these untagged images.
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.
$ hyper images --filter "label=com.example.version"
