Chapter 3. ImageSignature [image.openshift.io/v1]
Chapter 3. 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 Required type content 3.1. 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 conditions array Conditions represent the latest available observations of a signature's current state. conditions[] object SignatureCondition describes an image signature condition of particular kind at particular probe time. content string Required: An opaque binary string which is an image's signature. created Time If specified, it is the time of signature's creation. imageIdentity string A human readable string representing image's identity. It could be a product name and version, or an image pull spec (e.g. "registry.access.redhat.com/rhel7/rhel:7.2"). issuedBy object SignatureIssuer holds information about an issuer of signing certificate or key. issuedTo object SignatureSubject holds information about a person or entity who created the signature. 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 signedClaims object (string) Contains claims from the signature. type string Required: Describes a type of stored blob. 3.1.1. .conditions Description Conditions represent the latest available observations of a signature's current state. Type array 3.1.2. .conditions[] Description SignatureCondition describes an image signature condition of particular kind at particular probe time. Type object Required type status Property Type Description lastProbeTime Time Last time the condition was checked. lastTransitionTime Time Last time the condition transit from one status to another. message string Human readable message indicating details about last transition. reason string (brief) reason for the condition's last transition. status string Status of the condition, one of True, False, Unknown. type string Type of signature condition, Complete or Failed. 3.1.3. .issuedBy Description SignatureIssuer holds information about an issuer of signing certificate or key. Type object Property Type Description commonName string Common name (e.g. openshift-signing-service). organization string Organization name. 3.1.4. .issuedTo Description SignatureSubject holds information about a person or entity who created the signature. Type object Required publicKeyID Property Type Description commonName string Common name (e.g. openshift-signing-service). organization string Organization name. publicKeyID string If present, it is a human readable key id of public key belonging to the subject used to verify image signature. It should contain at least 64 lowest bits of public key's fingerprint (e.g. 0x685ebe62bf278440). 3.2. API endpoints The following API endpoints are available: /apis/image.openshift.io/v1/imagesignatures POST : create an ImageSignature /apis/image.openshift.io/v1/imagesignatures/{name} DELETE : delete an ImageSignature 3.2.1. /apis/image.openshift.io/v1/imagesignatures Table 3.1. 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 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. HTTP method POST Description create an ImageSignature Table 3.2.
