Types

type Controller

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

Controller is the controller which, among other things: - loads configuration from disk - checkpoints configuration to disk - downloads new configuration from the API server - validates configuration - monitors for potential crash-loops caused by new configurations - tracks the last-known-good configuration, and rolls-back to last-known-good when necessary For more information, see the proposal: https://github.com/kubernetes/kubernetes/pull/29459

func NewController

func NewController(initConfigDir string, dynamicConfigDir string, defaultConfig *kubeletconfig.KubeletConfiguration) *Controller

NewController constructs a new Controller object and returns it. Directory paths must be absolute. If the `initConfigDir` is an empty string, skips trying to load the init config. If the `dynamicConfigDir` is an empty string, skips trying to load checkpoints or download new config, but will still sync the ConfigOK condition if you call StartSync with a non-nil client.

func (*Controller) Bootstrap

func (cc *Controller) Bootstrap() (*kubeletconfig.KubeletConfiguration, error)

Bootstrap attempts to return a valid KubeletConfiguration based on the configuration of the Controller, or returns an error if no valid configuration could be produced. Bootstrap should be called synchronously before StartSync.

func (*Controller) StartSync

func (cc *Controller) StartSync(client clientset.Interface, nodeName string)

StartSync launches the controller's sync loops if `client` is non-nil and `nodeName` is non-empty. It will always start the Node condition reporting loop, and will also start the dynamic conifg sync loops if dynamic config is enabled on the controller. If `nodeName` is empty but `client` is non-nil, an error is logged.
