Class GkeHubClient (2.18.0)

The GKE Hub service handles the registration of many Kubernetes clusters to Google Cloud, and the management of multi-cluster features over those clusters.

The GKE Hub service operates on the following resources:

GKE Hub is currently available in the global region and all regions in https://cloud.google.com/compute/docs/regions-zones. Feature is only available in global region while membership is global region and all the regions.

Membership management may be non-trivial: it is recommended to use one of the Google-provided client libraries or tools where possible when working with Membership resources.

Equality

Instances of this class created via copy-construction or copy-assignment always compare equal. Instances created with equal std::shared_ptr<*Connection> objects compare equal. Objects that compare equal share the same underlying resources.

Performance

Creating a new instance of this class is a relatively expensive operation, new objects establish new connections to the service. In contrast, copy-construction, move-construction, and the corresponding assignment operations are relatively efficient as the copies share all underlying resources.

Thread Safety

Concurrent access to different instances of this class, even if they compare equal, is guaranteed to work. Two or more threads operating on the same instance of this class is not guaranteed to work. Since copy-construction and move-construction is a relatively efficient operation, consider using such a copy when using this class from multiple threads.

Functions

ListMemberships(std::string const &, Options)

Lists Memberships in a given project and location.

Parameters
Name Description
parent std::string const &

Required. The parent (project and location) where the Memberships will be listed. Specified in the format projects/*/locations/*. projects/*/locations/- list memberships in all the regions.

opts Options

Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type Description
StreamRange< google::cloud::gkehub::v1::Membership >

a StreamRange to iterate of the results. See the documentation of this type for details. In brief, this class has begin() and end() member functions returning a iterator class meeting the input iterator requirements. The value type for this iterator is a StatusOr as the iteration may fail even after some values are retrieved successfully, for example, if there is a network disconnect. An empty set of results does not indicate an error, it indicates that there are no resources meeting the request criteria. On a successful iteration the StatusOr<T> contains elements of type google.cloud.gkehub.v1.Membership, or rather, the C++ class generated by Protobuf from that type. Please consult the Protobuf documentation for details on the Protobuf mapping rules.
