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 NewVolumeProvisioner

func NewVolumeProvisioner(cloud cloudprovider.Interface, flags VolumeConfigFlags) (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 ProbeRecyclableVolumePlugins

func ProbeRecyclableVolumePlugins(flags VolumeConfigFlags) []volume.VolumePlugin

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

CMServer is the main context object for the controller manager.

func NewCMServer

func NewCMServer() *CMServer

NewCMServer creates a new CMServer with a default config.

func (*CMServer) AddFlags

func (s *CMServer) AddFlags(fs *pflag.FlagSet)

AddFlags adds flags for a specific CMServer to the specified FlagSet

func (*CMServer) ResyncPeriod

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

func (*CMServer) Run

func (s *CMServer) Run(_ []string) error

Run runs the CMServer. This should never exit.

type VolumeConfigFlags

type VolumeConfigFlags struct {
	PersistentVolumeRecyclerMinimumTimeoutNFS           int
	PersistentVolumeRecyclerPodTemplateFilePathNFS      string
	PersistentVolumeRecyclerIncrementTimeoutNFS         int
	PersistentVolumeRecyclerPodTemplateFilePathHostPath string
	PersistentVolumeRecyclerMinimumTimeoutHostPath      int
	PersistentVolumeRecyclerIncrementTimeoutHostPath    int
	EnableHostPathProvisioning                          bool
}

VolumeConfigFlags is used to bind CLI flags to variables. This top-level struct contains *all* enumerated CLI flags meant to configure all volume plugins. From this config, the binary will create many instances of volume.VolumeConfig which are then passed to the appropriate plugin. The ControllerManager binary is the only part of the code which knows what plugins are supported and which CLI flags correspond to each plugin.
