Functions

func IsExitSignal

func IsExitSignal(s os.Signal) (bool, bool)

IsExitSignal returns a flag indicating whether a signal is SIGKILL, SIGHUP, SIGINT, SIGTERM, or SIGQUIT. The second return value is whether it is a graceful exit. This flag is true for SIGTERM, SIGHUP, SIGINT, and SIGQUIT.

func RegisterSignalHandler

func RegisterSignalHandler(f SignalHandlerFunc)

RegisterSignalHandler registers a SignalHandlerFunc.

func TrapSignals

func TrapSignals(ctx apitypes.Context)

TrapSignals tells the process to trap incoming process signals.

Types

type SignalHandlerFunc

type SignalHandlerFunc func(ctx apitypes.Context, s os.Signal)

SignalHandlerFunc is a function that can be registered with `core.RegisterSignalHandler` to receive a callback when the process receives a signal.
