Retrieves a list of resources that refer to the VM instance specified in the request. For example, if the VM instance is part of a managed or unmanaged instance group, the referrers list includes the instance group. For more information, read Viewing referrers to VM instances.
HTTP request
GET https://compute.googleapis.com/compute/beta/projects/{project}/zones/{zone}/instances/{resourceId}/referrers
The URL uses gRPC Transcoding syntax.

pageToken |
Specifies a page token to use. Set |
filter |
A filter expression that filters resources listed in the response. The expression must specify the field name, a comparison operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The comparison operator must be either For example, if you are filtering Compute Engine instances, you can exclude instances named You can also filter nested fields. For example, you could specify To filter on multiple expressions, provide each separate expression within parentheses. For example:
By default, each expression is an
|
orderBy |
Sorts list results by a certain order. By default, results are returned in alphanumerical order based on the resource name. You can also sort results in descending order based on the creation timestamp using Currently, only sorting by |
returnPartialSuccess |
Opt-in for partial success behavior which provides partial results in case of failure. The default value is false. |
Request body
The request body must be empty.
