Overview

Package app implements a server that runs a set of active components. This includes replication controllers, service endpoints and nodes.

CAUTION: If you update code in this file, you may need to also update code

Functions

func AttemptToLoadRecycler

func AttemptToLoadRecycler(path string, config *volume.VolumeConfig) error

AttemptToLoadRecycler tries decoding a pod from a filepath for use as a recycler for a volume. If successful, this method will set the recycler on the config. If unsuccessful, an error is returned. Function is exported for reuse downstream.

func NewControllerManagerCommand

func NewControllerManagerCommand() *cobra.Command

NewControllerManagerCommand creates a *cobra.Command object with default parameters

func NewVolumeProvisioner

func NewVolumeProvisioner(cloud cloudprovider.Interface, config componentconfig.VolumeConfiguration) (volume.ProvisionableVolumePlugin, error)

NewVolumeProvisioner returns a volume provisioner to use when running in a cloud or development environment. The beta implementation of provisioning allows 1 implied provisioner per cloud, until we allow configuration of many. We explicitly map clouds to volume plugins here which allows us to configure many later without backwards compatibility issues. Not all cloudproviders have provisioning capability, which is the reason for the bool in the return to tell the caller to expect one or not.

func ProbeAttachableVolumePlugins

func ProbeAttachableVolumePlugins(config componentconfig.VolumeConfiguration) []volume.VolumePlugin

ProbeAttachableVolumePlugins collects all volume plugins for the attach/ detach controller. VolumeConfiguration is used ot get FlexVolumePluginDir which specifies the directory to search for additional third party volume plugins. The list of plugins is manually compiled. This code and the plugin initialization code for kubelet really, really need a through refactor.

func ProbeRecyclableVolumePlugins

func ProbeRecyclableVolumePlugins(config componentconfig.VolumeConfiguration) []volume.VolumePlugin

ProbeRecyclableVolumePlugins collects all persistent volume plugins into an easy to use list.

func ResyncPeriod

func ResyncPeriod(s *options.CMServer) func() time.Duration

func Run

func Run(s *options.CMServer) error

Run runs the CMServer. This should never exit.

func StartControllers

func StartControllers(s *options.CMServer, kubeClient *client.Client, kubeconfig *restclient.Config, stop <-chan struct{}) error
