Cannot pipe data to docker container

[PeterKietzmann]

I've tried:

python examples/test_rng_example.py | docker run --rm -it <name>:latest --small-crush` 

but unfortunately I get errors with the PIPE:

the input device is not a TTY
Exception ignored in: <_io.TextIOWrapper name='<stdout>' mode='w' encoding='UTF-8'>
BrokenPipeError: [Errno 32] Broken pipe

• Starting the container without the pipe works. I shows the initial log outputs of "SmallCrush" and waits for data.
• Starting docker only with -i does not show the error, it starts the SmallCrush as expected but the input data is a static and unrelated value.

Now I'm not so familiar with docker and for sure i googled and tried varying parameters but all without success. Do you have an suggestions how to fix this?

PS: I totally forget to say thanks for this contribution :-)! It is really helpful and simplifies usage of the TestU01 library a lot – if only I got it running.

Got the same error. Just remove t flag from testu01 container due to not the TTY device:

python examples/test_rng_example.py | docker run --rm -i <name>:latest --small-crush
