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/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 pkg/runtime`	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/api-conventions.md#types-kinds
`.metadata`	`ObjectMeta meta/v1`	Standard object’s 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.

Table 1. Global guery parameters
Parameter	Type	Description
`pretty`	`string`	If 'true', then the output is pretty printed.

HTTP method: DELETE
Description: delete collection of Image

Table 2. Query parameters
Parameter	Type	Description
`continue`	`string`	The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server the server will respond with a 410 ResourceExpired error indicating the client must restart their list without the continue field. This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
`fieldSelector`	`string`	A selector to restrict the list of returned objects by their fields. Defaults to everything.
`includeUninitialized`	`boolean`	If true, partially initialized resources are included in the response.
`labelSelector`	`string`	A selector to restrict the list of returned objects by their labels. Defaults to everything.
`limit`	`integer`	limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
`resourceVersion`	`string`	When specified with a watch call, shows changes that occur after that particular version of a resource. Defaults to changes from the beginning of history. When specified for list: - if unset, then the result is returned from remote storage based on quorum-read flag; - if it's 0, then we simply return what we currently have in cache, no guarantee; - if set to non zero, then the result is at least as fresh as given rv.
`timeoutSeconds`	`integer`	Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.
`watch`	`boolean`	Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion.

If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
`orphanDependents`	`boolean`	Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
`propagationPolicy`	`string`	Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
