Chapter 8. ImageStream [image.openshift.io/v1] Description An ImageStream stores a mapping of tags to images, metadata overrides that are applied when images are tagged in a stream, and an optional reference to a container image repository on a registry. Users typically update the spec.tags field to point to external images which are imported from container registries using credentials in your namespace with the pull secret type, or to existing image stream tags and images which are immediately accessible for tagging or pulling. The history of images applied to a tag is visible in the status.tags field and any user who can view an image stream is allowed to tag that image into their own image streams. Access to pull images from the integrated registry is granted by having the "get imagestreams/layers" permission on a given image stream. Users may remove a tag by deleting the imagestreamtag resource, which causes both spec and status for that tag to be removed. Image stream history is retained until an administrator runs the prune operation, which removes references that are no longer in use. To preserve a historical image, ensure there is a tag in spec pointing to that image by its digest. Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer). Type object 8.1. 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 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 metadata is the standard object's metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata spec object ImageStreamSpec represents options for ImageStreams. status object ImageStreamStatus contains information about the state of this image stream. 8.1.1. .spec Description ImageStreamSpec represents options for ImageStreams. Type object Property Type Description dockerImageRepository string dockerImageRepository is optional, if specified this stream is backed by a container repository on this server Deprecated: This field is deprecated as of v3.7 and will be removed in a future release. Specify the source for the tags to be imported in each tag via the spec.tags.from reference instead. 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. tags array tags map arbitrary string values to specific image locators tags[] object TagReference specifies optional annotations for images using this tag and an optional reference to an ImageStreamTag, ImageStreamImage, or DockerImage this tag should track. 8.1.2. .spec.lookupPolicy Description ImageLookupPolicy describes how an image stream can be used to override the image references used by pods, builds, and other resources in a namespace. Type object Required local Property Type Description local boolean local will change the docker short image references (like "mysql" or "php:latest") on objects in this namespace to the image ID whenever they match this image stream, instead of reaching out to a remote registry. The name will be fully qualified to an image ID if found. The tag's referencePolicy is taken into account on the replaced value. Only works within the current namespace. 8.1.3. .spec.tags Description tags map arbitrary string values to specific image locators Type array 8.1.4. .spec.tags[] Description TagReference specifies optional annotations for images using this tag and an optional reference to an ImageStreamTag, ImageStreamImage, or DockerImage this tag should track. Type object Required name Property Type Description annotations object (string) Optional; if specified, annotations that are applied to images retrieved via ImageStreamTags. from ObjectReference Optional; if specified, a reference to another image that this tag should point to. Valid values are ImageStreamTag, ImageStreamImage, and DockerImage. ImageStreamTag references can only reference a tag within this same ImageStream. generation integer Generation is a counter that tracks mutations to the spec tag (user intent). When a tag reference is changed the generation is set to match the current stream generation (which is incremented every time spec is changed). Other processes in the system like the image importer observe that the generation of spec tag is newer than the generation recorded in the status and use that as a trigger to import the newest remote tag. To trigger a new import, clients may set this value to zero which will reset the generation to the latest stream generation. Legacy clients will send this value as nil which will be merged with the current tag generation. importPolicy object TagImportPolicy controls how images related to this tag will be imported. name string Name of the tag reference boolean Reference states if the tag will be imported. Default value is false, which means the tag will be imported. referencePolicy object TagReferencePolicy describes how pull-specs for images in this image stream tag are generated when image change triggers in deployment configs or builds are resolved. This allows the image stream author to control how images are accessed. 8.1.5. .spec.tags[].importPolicy Description TagImportPolicy controls how images related to this tag will be imported. Type object Property Type Description importMode string ImportMode describes how to import an image manifest. insecure boolean Insecure is true if the server may bypass certificate verification or connect directly over HTTP during image import. scheduled boolean Scheduled indicates to the server that this tag should be periodically checked to ensure it is up to date, and imported 8.1.6. .spec.tags[].referencePolicy Description TagReferencePolicy describes how pull-specs for images in this image stream tag are generated when image change triggers in deployment configs or builds are resolved. This allows the image stream author to control how images are accessed. Type object Required type Property Type Description type string Type determines how the image pull spec should be transformed when the image stream tag is used in deployment config triggers or new builds. The default value is Source , indicating the original location of the image should be used (if imported). The user may also specify Local , indicating that the pull spec should point to the integrated container image registry and leverage the registry's ability to proxy the pull to an upstream registry. Local allows the credentials used to pull this image to be managed from the image stream's namespace, so others on the platform can access a remote image but have no access to the remote secret. It also allows the image layers to be mirrored into the local registry which the images can still be pulled even if the upstream registry is unavailable. 8.1.7. .status Description ImageStreamStatus contains information about the state of this image stream. Type object Required dockerImageRepository Property Type Description dockerImageRepository string DockerImageRepository represents the effective location this stream may be accessed at. May be empty until the server determines where the repository is located publicDockerImageRepository string PublicDockerImageRepository represents the public location from where the image can be pulled outside the cluster. This field may be empty if the administrator has not exposed the integrated registry externally. tags array Tags are a historical record of images associated with each tag. The first entry in the TagEvent array is the currently tagged image. tags[] object NamedTagEventList relates a tag to its image history. 8.1.8. .status.tags Description Tags are a historical record of images associated with each tag. The first entry in the TagEvent array is the currently tagged image. Type array 8.1.9. .status.tags[] Description NamedTagEventList relates a tag to its image history. Type object Required tag items Property Type Description conditions array Conditions is an array of conditions that apply to the tag event list. conditions[] object TagEventCondition contains condition information for a tag event. items array Standard object's metadata. items[] object TagEvent is used by ImageStreamStatus to keep a historical record of images associated with a tag. tag string Tag is the tag for which the history is recorded 8.1.10. .status.tags[].conditions Description Conditions is an array of conditions that apply to the tag event list. Type array 8.1.11. .status.tags[].conditions[] Description TagEventCondition contains condition information for a tag event. Type object Required type status generation Property Type Description generation integer Generation is the spec tag generation that this status corresponds to 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. type string Type of tag event condition, currently only ImportSuccess 8.1.12. .status.tags[].items Description Standard object's metadata. Type array 8.1.13. .status.tags[].items[] Description TagEvent is used by ImageStreamStatus to keep a historical record of images associated with a tag. Type object Required created dockerImageReference image generation Property Type Description created Time Created holds the time the TagEvent was created dockerImageReference string DockerImageReference is the string that can be used to pull this image generation integer Generation is the spec tag generation that resulted in this tag being updated image string Image is the image 8.2.
