Class ResourceDescriptor

A simple descriptor of a resource type.

ResourceDescriptor annotates a resource message (either by means of a protobuf annotation or use in the service config), and associates the resource's schema, the resource type, and the pattern of the resource name.

Example:

message Topic { // Indicates this message defines a resource schema. // Declares the resource type in the format of {service}/{kind}. // For Kubernetes resources, the format is {api group}/{kind}. option (google.api.resource) = { type: "pubsub.googleapis.com/Topic" name_descriptor: { pattern: "projects/{project}/topics/{topic}" parent_type: "cloudresourcemanager.googleapis.com/Project" parent_name_extractor: "projects/{project}" } }; }

The ResourceDescriptor Yaml config will look like:

resources:

  • type: "pubsub.googleapis.com/Topic" name_descriptor:
    • pattern: "projects/{project}/topics/{topic}" parent_type: "cloudresourcemanager.googleapis.com/Project" parent_name_extractor: "projects/{project}"

Sometimes, resources have multiple patterns, typically because they can live under multiple parents.

Example:

message LogEntry { option (google.api.resource) = { type: "logging.googleapis.com/LogEntry" name_descriptor: { pattern: "projects/{project}/logs/{log}" parent_type: "cloudresourcemanager.googleapis.com/Project" parent_name_extractor: "projects/{project}" } name_descriptor: { pattern: "folders/{folder}/logs/{log}" parent_type: "cloudresourcemanager.googleapis.com/Folder" parent_name_extractor: "folders/{folder}" } name_descriptor: { pattern: "organizations/{organization}/logs/{log}" parent_type: "cloudresourcemanager.googleapis.com/Organization" parent_name_extractor: "organizations/{organization}" } name_descriptor: { pattern: "billingAccounts/{billing_account}/logs/{log}" parent_type: "billing.googleapis.com/BillingAccount" parent_name_extractor: "billingAccounts/{billing_account}" } }; }

The ResourceDescriptor Yaml config will look like:

resources:

  • type: 'logging.googleapis.com/LogEntry' name_descriptor:
    • pattern: "projects/{project}/logs/{log}" parent_type: "cloudresourcemanager.googleapis.com/Project" parent_name_extractor: "projects/{project}"
    • pattern: "folders/{folder}/logs/{log}" parent_type: "cloudresourcemanager.googleapis.com/Folder" parent_name_extractor: "folders/{folder}"
    • pattern: "organizations/{organization}/logs/{log}" parent_type: "cloudresourcemanager.googleapis.com/Organization" parent_name_extractor: "organizations/{organization}"
    • pattern: "billingAccounts/{billing_account}/logs/{log}" parent_type: "billing.googleapis.com/BillingAccount" parent_name_extractor: "billingAccounts/{billing_account}"

For flexible resources, the resource name doesn't contain parent names, but the resource itself has parents for policy evaluation.

Example:

message Shelf { option (google.api.resource) = { type: "library.googleapis.com/Shelf" name_descriptor: { pattern: "shelves/{shelf}" parent_type: "cloudresourcemanager.googleapis.com/Project" } name_descriptor: { pattern: "shelves/{shelf}" parent_type: "cloudresourcemanager.googleapis.com/Folder" } }; }

The ResourceDescriptor Yaml config will look like:

resources:

  • type: 'library.googleapis.com/Shelf' name_descriptor:
    • pattern: "shelves/{shelf}" parent_type: "cloudresourcemanager.googleapis.com/Project"
    • pattern: "shelves/{shelf}" parent_type: "cloudresourcemanager.googleapis.com/Folder"

Properties

Descriptor

Declaration
public static MessageDescriptor Descriptor { get; }
Property Value
Type Description
MessageDescriptor

History

Optional. The historical or future-looking state of the resource pattern.

Example:

// The InspectTemplate message originally only supported resource // names with organization, and project was added later. message InspectTemplate { option (google.api.resource) = { type: "dlp.googleapis.com/InspectTemplate" pattern: "organizations/{organization}/inspectTemplates/{inspect_template}" pattern: "projects/{project}/inspectTemplates/{inspect_template}" history: ORIGINALLY_SINGLE_PATTERN }; }

Declaration
public ResourceDescriptor.Types.History History { get; set; }
Property Value
Type Description
ResourceDescriptor.Types.History

NameField

Optional. The field on the resource that designates the resource name field. If omitted, this is assumed to be "name".

Declaration
public string NameField { get; set; }
Property Value
Type Description
System.String

Parser

Declaration
public static MessageParser<ResourceDescriptor> Parser { get; }
Property Value
Type Description
MessageParser<ResourceDescriptor>

Pattern

Optional. The relative resource name pattern associated with this resource type. The DNS prefix of the full resource name shouldn't be specified here.

The path pattern must follow the syntax, which aligns with HTTP binding syntax:

Template = Segment { "/" Segment } ; Segment = LITERAL | Variable ; Variable = "{" LITERAL "}" ;

Examples:

  • "projects/{project}/topics/{topic}"
  • "projects/{project}/knowledgeBases/{knowledge_base}"

The components in braces correspond to the IDs for each resource in the hierarchy. It is expected that, if multiple patterns are provided, the same component name (e.g. "project") refers to IDs of the same type of resource.

Declaration
public RepeatedField<string> Pattern { get; }
Property Value
Type Description
RepeatedField<System.String>

Plural

The plural name used in the resource name, such as 'projects' for the name of 'projects/{project}'. It is the same concept of the plural field in k8s CRD spec https://kubernetes.io/docs/tasks/access-kubernetes-api/custom-resources/custom-resource-definitions/

Declaration
public string Plural { get; set; }
Property Value
Type Description
System.String

Singular

The same concept of the singular field in k8s CRD spec https://kubernetes.io/docs/tasks/access-kubernetes-api/custom-resources/custom-resource-definitions/ Such as "project" for the resourcemanager.googleapis.com/Project type.

Declaration
public string Singular { get; set; }
Property Value
Type Description
System.String

Type

The resource type. It must be in the format of {service_name}/{resource_type_kind}. The resource_type_kind must be singular and must not include version numbers.

Example: storage.googleapis.com/Bucket

The value of the resource_type_kind must follow the regular expression /[A-Za-z][a-zA-Z0-9]+/. It should start with an upper case character and should use PascalCase (UpperCamelCase). The maximum number of characters allowed for the resource_type_kind is 100.

Declaration
public string Type { get; set; }
Property Value
Type Description
System.String
