Can not work in docker container

[Hongfei-Niu]

When I ran the scripts pixels in docker container, it just has error like the following.

 File "/usr/local/src/test/mics_hat/interfaces/pixels.py", line 74, in <module>
    pixels = Pixels()
  File "/usr/local/src/test/mics_hat/interfaces/pixels.py", line 21, in __init__
    self.dev = apa102.APA102(num_led=self.PIXELS_N)
  File "/usr/local/src/test/mics_hat/interfaces/apa102.py", line 90, in __init__
    self.spi.open(bus, device)  # Open SPI port 0, slave device (CS) 1
FileNotFoundError: [Errno 2] No such file or directory

I am not familiar with the spidev, and not sure if linking the relevant device, when I ran the container, could fixed this error, like (docker run --device $path1:$path2 -it $image_id /bin/bash)

If I am right, could you please help me find the path of the device.
if I am wrong, could you please help me out with it.
