Description

ImageStreamTag represents an Image that is retrieved by tag name from an ImageStream. Use this resource to interact with the tags and images in an image stream by tag, or to see the image details for a particular tag. The image associated with this resource is the most recently successfully tagged, imported, or pushed image (as described in the image stream status.tags.items list for this tag). If an import is in progress or has failed the previous image will be shown. Deleting an image stream tag clears both the status and spec fields of an image stream. If no image can be retrieved for a given tag, a not found error will be returned.

Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer).

Specification

Property Type Description

apiVersion

string

APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources

conditions

array

conditions is an array of conditions that apply to the image stream tag.

conditions[]

object

TagEventCondition contains condition information for a tag event.

generation

integer

generation is the current generation of the tagged image - if tag is provided and this value is not equal to the tag generation, a user has requested an import that has not completed, or conditions will be filled out indicating any error.

image

object

Image is an immutable representation of a container image and metadata at a point in time. Images are named by taking a hash of their contents (metadata and content) and any change in format, content, or metadata results in a new name. The images resource is primarily for use by cluster administrators and integrations like the cluster image registry - end users instead access images via the imagestreamtags or imagestreamimages resources. While image metadata is stored in the API, any integration that implements the container image registry API must provide its own storage for the raw manifest data, image config, and layer contents.

Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer).

kind

string

Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds

lookupPolicy

object

ImageLookupPolicy describes how an image stream can be used to override the image references used by pods, builds, and other resources in a namespace.

metadata

ObjectMeta_v3

tag

object

TagReference specifies optional annotations for images using this tag and an optional reference to an ImageStreamTag, ImageStreamImage, or DockerImage this tag should track.

.conditions

conditions is an array of conditions that apply to the image stream tag.

Property Type Description

generation

integer

lastTransitionTime

Time

LastTransitionTIme is the time the condition transitioned from one status to another.

message

string

Message is a human readable description of the details about last transition, complementing reason.

reason

string

Reason is a brief machine readable explanation for the condition’s last transition.

status

string

Status of the condition, one of True, False, Unknown.

Property Type Description

apiVersion

string

APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources

dockerImageConfig

string

DockerImageConfig is a JSON blob that the runtime uses to set up the container. This is a part of manifest schema v2.

dockerImageLayers

array

DockerImageLayers represents the layers in the image. May not be set if the image does not define that data.

dockerImageLayers[]

object

ImageLayer represents a single layer of the image. Some images may have multiple layers. Some may have none.

dockerImageManifest

string

DockerImageManifest is the raw JSON of the manifest

dockerImageManifestMediaType

string

DockerImageManifestMediaType specifies the mediaType of manifest. This is a part of manifest schema v2.

dockerImageMetadata

RawExtension

DockerImageMetadata contains metadata about this image

dockerImageMetadataVersion

string

DockerImageMetadataVersion conveys the version of the object, which if empty defaults to "1.0"

dockerImageReference

string

DockerImageReference is the string that can be used to pull this image.

dockerImageSignatures

array (string)

DockerImageSignatures provides the signatures as opaque blobs. This is a part of manifest schema v1.

kind

string

Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds

metadata

signatures

array

Signatures holds all signatures of the image.

signatures[]

object

ImageSignature holds a signature of an image. It allows to verify image identity and possibly other claims as long as the signature is trusted. Based on this information it is possible to restrict runnable images to those matching cluster-wide policy. Mandatory fields should be parsed by clients doing image verification. The others are parsed from signature’s content by the server. They serve just an informative purpose.

Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer).

.image.dockerImageLayers

Description

DockerImageLayers represents the layers in the image. May not be set if the image does not define that data.
