func hello(w http.ResponseWriter, r *http.Request) {
    cl, _ := docker.NewClient("unix:///var/run/docker.sock")
    d := dexec.Docker{cl}

    m, _ := dexec.ByCreatingContainer(docker.CreateContainerOptions{
        Config: &docker.Config{Image: "busybox"}})

    cmd := d.Command(m, "echo", `I am running inside a container!`)
    b, err := cmd.Output()

    log.Printf("%s", b)
    io.WriteString(w, fmt.Sprintf("%s", b))
