podman-images(1)

NAME

podman-images - List images in local storage

SYNOPSIS

podman images [options] [image]

podman image list [options] [image]

podman image ls [options] [image]

DESCRIPTION

Displays locally stored images, their names, and their IDs.

OPTIONS

  --all, -a

Show all images (by default filter out the intermediate image layers). The default is false.

  --digests

Show image digests

  --filter, -f=filter

Provide filter values.

The filters argument format is of key=value or key!=value. If there is more than one filter, then pass multiple OPTIONS: --filter foo=bar --filter bif=baz.

Supported filters:
Filter | Description
id | Filter by image ID.
before | Filter by images created before the given IMAGE (name or tag).
containers | Filter by images with a running container.
dangling | Filter by dangling (unused) images.
digest | Filter by digest.
intermediate | Filter by images that are dangling and have no children
label | Filter by images with (or without, in the case of label!=[...] is used) the specified labels.
manifest | Filter by images that are manifest lists.
readonly | Filter by read-only or read/write images.
reference | Filter by image name.
after/since | Filter by images created after the given IMAGE (name or tag).
until | Filter by images created until the given duration or time.

The id filter accepts the image ID string.

The before filter accepts formats: <image-name>[:<tag>], <image id> or <image@digest>.

The containers filter shows images that have a running container based on that image.

The dangling filter shows images that are taking up disk space and serve no purpose. Dangling image is a file system layer that was used in a previous build of an image and is no longer referenced by any image. They are denoted with the <none> tag, consume disk space and serve no active purpose.

The digest filter accepts the image digest string.

The intermediate filter shows images that are dangling and have no children.

The label filter accepts two formats. One is the label=key or label=key=value, which shows images with the specified labels. The other format is the label!=key or label!=key=value, which shows images without the specified labels.

The manifest filter shows images that are manifest lists.

The readonly filter shows, as a default, both read-only and read/write images. Read-only images can be configured by modifying the additionalimagestores in the /etc/containers/storage.conf file.

The reference filter accepts the pattern of an image reference <image-name>[:<tag>].

The after or since filter accepts formats: <image-name>[:<tag>], <image id> or <image@digest>.

The until filter accepts formats: golang duration, RFC3339 time, or a Unix timestamp and shows all images that are created until that time.

  --format=format

Change the default output format. This can be of a supported type like 'json' or a Go template. Valid placeholders for the Go template are listed below:
Placeholder | Description
.Containers | Number of containers using this image
.Created | Elapsed time since the image was created
.CreatedAt | Time when the image was created, YYYY-MM-DD HH:MM:SS +nnnn
.CreatedSince | Same as .Created
.CreatedTime | Same as .CreatedAt
.Dangling | Same as .IsDangling
.Digest | Image digest
.History | History of the image layer
.ID | Image ID (truncated)
.Id | Image ID (full SHA)
.IsDangling | Is image dangling? (true/false)
.IsReadOnly | Is unage read-only? (true/false)
.Labels ... | map[] of labels
.Names | Image FQIN
.ParentId | Full SHA of parent image ID, or null (string)
.ReadOnly | Same as .IsReadOnly
.RepoDigests | map[] of zero or more repo/name@sha256:SHA strings
.Repository | Image repository
.RepoTags | map[] of zero or more FQIN strings for this image
.SharedSize | Always seems to be 0
.Size | Size of layer on disk (human-friendly string)
.Tag | Image tag
.VirtualSize | Size of layer on disk (bytes)

  --history

Display the history of image names. If an image gets re-tagged or untagged, then the image name history gets prepended (latest image first). This is especially useful when undoing a tag operation or an image does not contain any name because it has been untagged.

  --no-trunc

Do not truncate the output (default false).

  --noheading, -n

Omit the table headings from the listing.

  --quiet, -q

Lists only the image IDs.

  --sort=sort

Sort by created, id, repository, size or tag (default: created)
