ImageStreamMapping [image.openshift.io/v1] - Image APIs | API reference

Specification
API endpoints
- /apis/image.openshift.io/v1/namespaces/{namespace}/imagestreammappings

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

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

API endpoints

The following API endpoints are available:

/apis/image.openshift.io/v1/namespaces/{namespace}/imagestreammappings
- POST: create an ImageStreamMapping

/apis/image.openshift.io/v1/namespaces/{namespace}/imagestreammappings

Table 1. Global path parameters
Parameter	Type	Description
`namespace`	`string`	object name and auth scope, such as for teams and projects

Table 2. Global query parameters
Parameter	Type	Description
`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
`fieldManager`	`string`	fieldManager is a name associated with the actor or entity that is making these changes. The value must be less than or 128 characters long, and only contain printable characters, as defined by https://golang.org/pkg/unicode/#IsPrint.
`fieldValidation`	`string`	fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields, provided that the `ServerSideFieldValidation` feature gate is also enabled. 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 and is the default behavior when the `ServerSideFieldValidation` feature gate is disabled. - 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 when the `ServerSideFieldValidation` feature gate is enabled. - 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.
`pretty`	`string`	If 'true', then the output is pretty printed.
