ControllersDisabledByDefault is the controller disabled default when starting cloud-controller managers.

Functions

func CreateControllerContext

func CreateControllerContext(s *cloudcontrollerconfig.CompletedConfig, clientBuilder clientbuilder.ControllerClientBuilder, stop <-chan struct{}) (genericcontrollermanager.ControllerContext, error)

CreateControllerContext creates a context struct containing references to resources needed by the controllers such as the cloud provider and clientBuilder. rootClientBuilder is only used for the shared-informers client and token controller.

func KnownControllers

func KnownControllers() []string

KnownControllers indicate the default controller we are known.

func NewCloudControllerManagerCommand

func NewCloudControllerManagerCommand() *cobra.Command

NewCloudControllerManagerCommand creates a *cobra.Command object with default parameters

func ResyncPeriod

func ResyncPeriod(c *cloudcontrollerconfig.CompletedConfig) func() time.Duration

ResyncPeriod returns a function which generates a duration each time it is invoked; this is so that multiple controllers don't get into lock-step and all hammer the apiserver with list requests simultaneously.

func Run

func Run(ctx context.Context, c *cloudcontrollerconfig.CompletedConfig, h *controllerhealthz.MutableHealthzHandler) error

Run runs the ExternalCMServer. This should never exit.

func RunWrapper

func RunWrapper(s *options.CloudControllerManagerOptions, c *cloudcontrollerconfig.Config, h *controllerhealthz.MutableHealthzHandler) func(ctx context.Context)

RunWrapper adapts the ccm boot logic to the leader elector call back function

func StartHTTPServer

func StartHTTPServer(c *cloudcontrollerconfig.CompletedConfig, stopCh <-chan struct{}) (*controllerhealthz.MutableHealthzHandler, error)

StartHTTPServer starts the controller manager HTTP server
