Types

type Interface

type Interface interface {
	// Sync is the method that tries to sync the cluster.
	Sync(ctx context.Context) error

	// SyncOrchestratorStatus brings info from orchestrator on resource status
	SyncOrchestratorStatus(ctx context.Context) error
}

Interface is for cluster Factory

func New

func New(cluster *api.MysqlCluster, opt *options.Options, klient kubernetes.Interface,
	myClient myclientset.Interface, ns string, rec record.EventRecorder) Interface

New creates a new cluster factory
