ResourceDescriptor class final

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"
    pattern: "projects/{project}/topics/{topic}"
  };
}

The ResourceDescriptor Yaml config will look like:

resources:
- type: "pubsub.googleapis.com/Topic"
  pattern: "projects/{project}/topics/{topic}"

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"
    pattern: "projects/{project}/logs/{log}"
    pattern: "folders/{folder}/logs/{log}"
    pattern: "organizations/{organization}/logs/{log}"
    pattern: "billingAccounts/{billing_account}/logs/{log}"
  };
}

The ResourceDescriptor Yaml config will look like:

resources:
- type: 'logging.googleapis.com/LogEntry'
  pattern: "projects/{project}/logs/{log}"
  pattern: "folders/{folder}/logs/{log}"
  pattern: "organizations/{organization}/logs/{log}"
  pattern: "billingAccounts/{billing_account}/logs/{log}"
