Constants

const RestartSignal = syscall.SIGUSR2

RestartSignal is the signal that causes the pod to be restarted.

Functions

func Restart

func Restart(
	ctx context.Context,
	k8sClient ctrlclient.Client,
	reason string) error

Restart instructs the Deployment responsible for this pod to do a rollout, restarting all of the replicas. By using this method, at least one pod is always up and responsive.

Types

type RestartSignalHandler

type RestartSignalHandler interface {
	Close()
	Closed() <-chan struct{}
}

RestartSignalHandler waits to receive a signal that tells the pod to restart.

func NewRestartSignalHandler

func NewRestartSignalHandler(
	ctx context.Context,
	k8sClient ctrlclient.Client,
	elected <-chan struct{}) RestartSignalHandler

NewRestartSignalHandler returns a new signal handler that waits to receive a SIGUSR2 signal, upon which the pod is restarted via the package's Restart(context.Context, ctrlclient.Client, string) error method. Calling the handler's Close() method will stop the signal handler.
