示例1: GetOnionHostname

content, stat, err := cli.CopyFromContainer(containerID, HostnamePath)
// XXX: This isn't very pretty. But we need to wait until Tor generates
// an .onion address, and there's not really any better way of
// doing it.
for err != nil && strings.Contains(err.Error(), "no such file or directory") {
// Make sure the container hasn't died.
if inspect, err := cli.ContainerInspect(containerID); err != nil {
return "", fmt.Errorf("error inspecting container: %s", err)
} else if !isRunning(inspect.State) {
