Functions

func StartClusterController

func StartClusterController(config *util.ControllerConfig, clusterHealthCheckConfig *util.ClusterHealthCheckConfig, stopChan <-chan struct{}) error

StartClusterController starts a new cluster controller.

Types

type ClusterClient

type ClusterClient struct {
	// contains filtered or unexported fields
}

ClusterClient provides methods for determining the status and zones of a particular KubeFedCluster.

func NewClusterClientSet

func NewClusterClientSet(c *fedv1b1.KubeFedCluster, client generic.Client, fedNamespace string, timeout time.Duration) (*ClusterClient, error)

NewClusterClientSet returns a ClusterClient for the given KubeFedCluster. The kubeClient is used to configure the ClusterClient's internal client with information from a kubeconfig stored in a kubernetes secret.

func (*ClusterClient) GetClusterStatus

func (c *ClusterClient) GetClusterStatus() (*fedv1b1.KubeFedClusterStatus, error)

GetClusterStatus gets the kubernetes cluster's health and version status

func (*ClusterClient) GetClusterZones

func (c *ClusterClient) GetClusterZones() ([]string, string, error)

GetClusterZones gets the kubernetes cluster zones and region by inspecting labels on nodes in the cluster.

type ClusterController

type ClusterController struct {
	// contains filtered or unexported fields
}

ClusterController is responsible for maintaining the health status of each KubeFedCluster in a particular namespace.

func (*ClusterController) RecordError

func (cc *ClusterController) RecordError(cluster runtimeclient.Object, errorCode string, err error)

func (*ClusterController) Run

func (cc *ClusterController) Run(stopChan <-chan struct{})

Run begins watching and syncing.

type ClusterData

type ClusterData struct {
	// contains filtered or unexported fields
}

ClusterData stores cluster client and previous health check probe results of individual cluster.
