The GKE Hub service handles the registration of many Kubernetes clusters to Google Cloud, and the management of multi-cluster features over those clusters.
A factory function to construct an object of typeGkeHubConnection.
The returned connection object should not be used directly; instead it should be passed as an argument to the constructor ofGkeHubClient.
The optionaloptionsargument may be used to configure aspects of the returnedGkeHubConnection. Expected options are any of the types in the following option lists:
