ImageStreamMapping [image.openshift.io/v1]

Description

ImageStreamMapping represents a mapping from a single image stream tag to a container image as well as the reference to the container image stream the image came from. This resource is used by privileged integrators to create an image resource and to associate it with an image stream in the status tags field. Creating an ImageStreamMapping will allow any user who can view the image stream to tag or pull that image, so only create mappings where the user has proven they have access to the image contents directly. The only operation supported for this resource is create and the metadata name and namespace should be set to the image stream containing the tag that should be updated.

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

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

metadata

ObjectMeta_v3

tag

string

Tag is a string value this image can be located with inside the stream.

.image

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
