image.run_via_binary_in_foreground raises conu.exceptions.CountExceeded

[b10n1k]

i have a problem when i try to create a container with run_via_binary_in_foreground

container = image.run_via_binary_in_foreground(volumes=(base_path, "/opt"),
                                                          additional_opts=["--net=host",
                                                                           "--pid=host",
                                                                           "--ipc=host",
                                                                           "-i",
    
                                                                           "--cap-add", "SYS_ADMIN",
                                                                           "--privileged",
                                                                           "-w=/opt"],
                                                          popen_params={"stdin": subprocess.PIPE,
                                                                        "stdout": subprocess.PIPE})

the trace is

tests/conftest.py:24:

---

../../../.virtualenvs/pytest_env/lib/python3.9/site-packages/conu/backend/docker/image.py:540: in run_via_binary_in_foreground

../../../.virtualenvs/pytest_env/lib/python3.9/site-packages/conu/utils/probes.py:54: in run
return self._run()

i cant find anything in the documentation. Can someone help me understand what am i doing wrong?

This error message means there was a timeout (might be set too low). How long does it take the image to run using CLI?

[b10n1k]

not long. ~1s
0.94s user 0.25s system 37% cpu 3.154 total

i also tried with the example from the repo https://github.com/user-cont/conu/blob/master/docs/source/examples/check_env.py
replacing the registry.fedoraproject.org/fedora with docker.io fedora and seems to have the same issue

i am still looking for some help or documentation of how i can change the timeout properly and use the run_via_binary_in_foreground. is there a channel for communication/support?
