Image APIs


OpenShift Container Platform 4.17

Reference guide for image APIs

Red Hat OpenShift Documentation Team

Abstract

This document describes the OpenShift Container Platform image API objects and their detailed specifications.

Chapter 1. Image APIs

1.1. Image [image.openshift.io/v1]

Description

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).

Type
object

1.2. ImageSignature [image.openshift.io/v1]

Description

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).

Type
object

1.3. ImageStreamImage [image.openshift.io/v1]

Description

ImageStreamImage represents an Image that is retrieved by image name from an ImageStream. User interfaces and regular users can use this resource to access the metadata details of a tagged image in the image stream history for viewing, since Image resources are not directly accessible to end users. A not found error will be returned if no such image is referenced by a tag within the ImageStream. Images are created when spec tags are set on an image stream that represent an image in an external registry, when pushing to the integrated registry, or when tagging an existing image from one image stream to another. The name of an image stream image is in the form "<STREAM>@<DIGEST>", where the digest is the content addressible identifier for the image (sha256:xxxxx…​). You can use ImageStreamImages as the from.kind of an image stream spec tag to reference an image exactly. The only operations supported on the imagestreamimage endpoint are retrieving the image.

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

Type
object

1.4. ImageStreamImport [image.openshift.io/v1]

Description

The image stream import resource provides an easy way for a user to find and import container images from other container image registries into the server. Individual images or an entire image repository may be imported, and users may choose to see the results of the import prior to tagging the resulting images into the specified image stream.

This API is intended for end-user tools that need to see the metadata of the image prior to import (for instance, to generate an application from it). Clients that know the desired image can continue to create spec.tags directly into their image streams.

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

Type
object

1.5. ImageStreamLayers [image.openshift.io/v1]

Description

ImageStreamLayers describes information about the layers referenced by images in this image stream.

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

Type
object

1.6. 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).

Type
object

1.7. 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

1.8. ImageStreamTag [image.openshift.io/v1]

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).

Type
object

1.9. ImageTag [image.openshift.io/v1]

Description

ImageTag represents a single tag within an image stream and includes the spec, the status history, and the currently referenced image (if any) of the provided tag. This type replaces the ImageStreamTag by providing a full view of the tag. ImageTags are returned for every spec or status tag present on the image stream. If no tag exists in either form a not found error will be returned by the API. A create operation will succeed if no spec tag has already been defined and the spec field is set. Delete will remove both spec and status elements from the image stream.

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

Type
object

1.10. SecretList [image.openshift.io/v1]

Description
SecretList is a list of Secret.
Type
object

Chapter 2. Image [image.openshift.io/v1]

Description

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.

ImageStreamImage represents an Image that is retrieved by image name from an ImageStream. User interfaces and regular users can use this resource to access the metadata details of a tagged image in the image stream history for viewing, since Image resources are not directly accessible to end users. A not found error will be returned if no such image is referenced by a tag within the ImageStream. Images are created when spec tags are set on an image stream that represent an image in an external registry, when pushing to the integrated registry, or when tagging an existing image from one image stream to another. The name of an image stream image is in the form "<STREAM>@<DIGEST>", where the digest is the content addressible identifier for the image (sha256:xxxxx…​). You can use ImageStreamImages as the from.kind of an image stream spec tag to reference an image exactly. The only operations supported on the imagestreamimage endpoint are retrieving the image.

PropertyTypeDescription

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.

Chapter 5. ImageStreamImport [image.openshift.io/v1]

Description

The image stream import resource provides an easy way for a user to find and import container images from other container image registries into the server. Individual images or an entire image repository may be imported, and users may choose to see the results of the import prior to tagging the resulting images into the specified image stream.

This API is intended for end-user tools that need to see the metadata of the image prior to import (for instance, to generate an application from it). Clients that know the desired image can continue to create spec.tags directly into their image streams.

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

images[]

object

ImageImportStatus describes the result of an image import.

import

object

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.

Type
array

5.1.24. .status.images[].manifests[]

Description

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).

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.

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.

PropertyTypeDescription

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.

array

5.1.64. .status.repository.images[].manifests[]

Description

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).

Chapter 7. 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.

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).

PropertyTypeDescription

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
PropertyTypeDescription

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
PropertyTypeDescription

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

Type
object
PropertyTypeDescription

importMode

string

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
PropertyTypeDescription

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.

Chapter 9. ImageStreamTag [image.openshift.io/v1]

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).

Chapter 10. ImageTag [image.openshift.io/v1]

Description

ImageTag represents a single tag within an image stream and includes the spec, the status history, and the currently referenced image (if any) of the provided tag. This type replaces the ImageStreamTag by providing a full view of the tag. ImageTags are returned for every spec or status tag present on the image stream. If no tag exists in either form a not found error will be returned by the API. A create operation will succeed if no spec tag has already been defined and the spec field is set. Delete will remove both spec and status elements from the image stream.

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.

ParameterTypeDescription

dryRun

string

When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed

fieldValidation

string

fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered.
