Functions ¶
func AttemptToLoadRecycler ¶ added in v1.2.0
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 GetAvailableResources ¶ added in v1.7.0
func GetAvailableResources(clientBuilder controller.ControllerClientBuilder) (map[schema.GroupVersionResource]bool, error)
TODO: In general, any controller checking this needs to be dynamic so
users don't have to restart their controller manager if they change the apiserver.
Until we get there, the structure here needs to be exposed for the construction of a proper ControllerContext.
func GetDynamicPluginProber ¶ added in v1.8.0
func GetDynamicPluginProber(config componentconfig.VolumeConfiguration) volume.DynamicPluginProber
GetDynamicPluginProber gets the probers of dynamically discoverable plugins for the attach/detach controller. Currently only Flexvolume plugins are dynamically discoverable.
func IsControllerEnabled ¶ added in v1.6.0
func KnownControllers ¶ added in v1.6.0
func KnownControllers() []string
func NewControllerInitializers ¶ added in v1.7.0
NewControllerInitializers is a public map of named controller groups (you can start more than one in an init func) paired to their InitFunc. This allows for structured downstream composition and subdivision.
func NewControllerManagerCommand ¶ added in v1.1.1
NewControllerManagerCommand creates a *cobra.Command object with default parameters
func ProbeAttachableVolumePlugins ¶ added in v1.3.0
func ProbeAttachableVolumePlugins() []volume.VolumePlugin
ProbeAttachableVolumePlugins collects all volume plugins for the attach/ detach controller. The list of plugins is manually compiled. This code and the plugin initialization code for kubelet really, really need a through refactor.
func ProbeControllerVolumePlugins ¶ added in v1.4.1
func ProbeControllerVolumePlugins(cloud cloudprovider.Interface, config componentconfig.VolumeConfiguration) []volume.VolumePlugin
ProbeControllerVolumePlugins collects all persistent volume plugins into an easy to use list. Only volume plugins that implement any of provisioner/recycler/deleter interface should be returned.
func ProbeExpandableVolumePlugins ¶ added in v1.8.0
func ProbeExpandableVolumePlugins(config componentconfig.VolumeConfiguration) []volume.VolumePlugin
ProbeExpandableVolumePlugins returns volume plugins which are expandable
func ResyncPeriod ¶ added in v1.2.0
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 StartControllers ¶ added in v1.2.0
func StartControllers(ctx ControllerContext, startSATokenController InitFunc, controllers map[string]InitFunc) error
Types ¶
type ControllerContext ¶ added in v1.6.0
type ControllerContext struct { // ClientBuilder will provide a client for this controller to use ClientBuilder controller.ControllerClientBuilder // InformerFactory gives access to informers for the controller. InformerFactory informers.SharedInformerFactory // Options provides access to init options for a given controller Options options.CMServer // AvailableResources is a map listing currently available resources AvailableResources map[schema.GroupVersionResource]bool // Cloud is the cloud provider interface for the controllers to use. // It must be initialized and ready to use. Cloud cloudprovider.Interface // Stop is the stop channel Stop <-chan struct{} // InformersStarted is closed after all of the controllers have been initialized and are running. After this point it is safe, // for an individual controller to start the shared informers. Before it is closed, they should not. InformersStarted chan struct{} }
func CreateControllerContext ¶ added in v1.7.0
func CreateControllerContext(s *options.CMServer, rootClientBuilder, clientBuilder controller.ControllerClientBuilder, stop <-chan struct{}) (ControllerContext, error)
func (ControllerContext) IsControllerEnabled ¶ added in v1.6.0
func (c ControllerContext) IsControllerEnabled(name string) bool
type InitFunc ¶ added in v1.6.0
type InitFunc func(ctx ControllerContext) (bool, error)
InitFunc is used to launch a particular controller. It may run additional "should I activate checks". Any error returned will cause the controller process to `Fatal` The bool indicates whether the controller was enabled.
