示例1: containerStop
// containerStop halts a container by sending a stop signal, waiting for the given
// duration in seconds, and then calling SIGKILL and waiting for the
// process to exit. If a negative duration is given, Stop will wait
// for the initial signal forever. If the container is not running Stop returns
// immediately.
func (daemon *Daemon) containerStop(container *container.Container, seconds int) error {
if !container.IsRunning() {
return nil
}
stopSignal := container.StopSignal()
// 1. Send a stop signal
if err := daemon.killPossiblyDeadProcess(container, stopSignal); err != nil {
logrus.Infof("Failed to send signal %d to the process, force killing", stopSignal)
if err := daemon.killPossiblyDeadProcess(container, 9); err != nil {
return err
}
}
// 2. Wait for the process to exit on its own
if _, err := container.WaitStop(time.Duration(seconds) * time.Second); err != nil {
logrus.Infof("Container %v failed to exit within %d seconds of signal %d - using the force", container.ID, seconds, stopSignal)
// 3. If it doesn't, then send SIGKILL
if err := daemon.Kill(container); err != nil {
container.WaitStop(-1 * time.Second)
logrus.Warn(err) // Don't return error because we only care that container is stopped, not what function stopped it
}
}
daemon.LogContainerEvent(container, "stop")
return nil
}
示例2: containerStop
// containerStop halts a container by sending a stop signal, waiting for the given
// duration in seconds, and then calling SIGKILL and waiting for the
// process to exit. If a negative duration is given, Stop will wait
// for the initial signal forever. If the container is not running Stop returns

daemon.stopHealthchecks(container)
stopSignal := container.StopSignal()
// 1. Send a stop signal
if err := daemon.killPossiblyDeadProcess(container, stopSignal); err != nil {
// While normally we might "return err" here we're not going to
// because if we can't stop the container by this point then
// it's probably because it's already stopped. Meaning, between
// the time of the IsRunning() call above and now it stopped.
// Also, since the err return will be environment specific we can't
// look for any particular (common) error that would indicate
// that the process is already dead vs something else going wrong.
// So, instead we'll give it up to 2 more seconds to complete and if
// by that time the container is still running, then the error
// we got is probably valid and so we force kill it.
if _, err := container.WaitStop(2 * time.Second); err != nil {
logrus.Infof("Container failed to stop after sending signal %d to the process, force killing", stopSignal)
