Docker run does not display any output

I ran into the same issue on a Raspberry Pi 1B+ (armv6l). Inspired by @JanDrábek’s answer, the first observation is that the hello-world image would indeed be one supporting ARM, yet only after using hypriot/armhf-hello-world instead did I get the expected output:

$ uname -a
Linux 4.1.19+ #858 Tue Mar 15 15:52:03 GMT 2016 armv6l GNU/Linux
$ docker run hello-world  # No output
$ docker image inspect hello-world | grep Architecture  # Arch looks right though
        "Architecture": "arm",
$ docker run hypriot/armhf-hello-world  # This does the job
Hello from Docker.
