示例1: TestDestroyWithInitLayer

func TestDestroyWithInitLayer(t *testing.T) {
	daemon := mkDaemon(t)
	defer nuke(daemon)

	container, _, err := daemon.Create(&runconfig.Config{
		Image: GetTestImage(daemon).ID,
		Cmd:   []string{"ls", "-al"},
	},
		&runconfig.HostConfig{},
		"")

	if err != nil {
		t.Fatal(err)
	}
	// Destroy
	if err := daemon.Destroy(container); err != nil {
		t.Fatal(err)
	}

	// Make sure daemon.Exists() behaves correctly
	if daemon.Exists("test_destroy") {
		t.Fatalf("Exists() returned true")
	}

	// Make sure daemon.List() doesn't list the destroyed container
	if len(daemon.List()) != 0 {
		t.Fatalf("Expected 0 container, %v found", len(daemon.List()))
