Mount device driver package to Docker container

Question

I am trying to access a NI cDAQ device from a Python script in a Docker container, using this python script (as a start):

import nidaqmx

task = nidaqmx.Task()
task.do_channels.add_do_chan(lines="cDAQ1Mod1/port0/line0")
task.write(1)

I have failed to install the device driver using this Dockerfile:

FROM ubuntu:latest

ENV DEBIAN_FRONTEND noninteractive

RUN apt update && apt-get install -y \
    apt-utils \
    python3 \
    pip
RUN pip install --no-cache-dir nidaqmx

COPY ni_drivers.deb ./
RUN apt install ./ni_drivers.deb
RUN apt update && apt install -y \
    ni-xnet \
    ni-daqmx \
    ni-serial
RUN dkms autoinstall

COPY hellodaq.py ./
CMD ["python3", "./hellodaq.py"]

During the build, I get the following message:

Error! Bad return status for module build on kernel: 5.15.0-43-generic (x86_64)
Consult /var/lib/dkms/ni843x/21.5.0f124/build/make.log for more information.
dpkg: error processing package ni-843x-dkms (--configure):
 installed ni-843x-dkms package post-installation script subprocess returned error exit status 10

And ultimately:

E: Sub-process /usr/bin/dpkg returned an error code (1)

(whats the best way of reading var/lib/dkms/ni843x/21.5.0f124/build/make.log? Since the build fails I cannot run the container.)

Therefore I tried to run the script in a Docker without the device driver:

FROM ubuntu:latest    

RUN apt update && apt-get install -y \
    python3 \
    pip

RUN pip install --no-cache-dir nidaqmx    
COPY hellodaq.py ./
CMD ["python3", "./hellodaq.py"]

As a replacement, I tried to mount the device driver from the host system:

sudo docker run \
--mount type=bind,source=/usr/lib/x86_64-linux-gnu/ni-daqmx,target=/usr/lib/x86_64-linux-gnu/ni-daqmx \
--mount type=bind,source=/usr/share/ni-daqmx,target=/usr/share/ni-daqmx \
hellodaq

However, this has not resolved the issue, and the python script cannot access the device driver.

Is it even possible to mount installed deb packages, device drivers specifically? Did I forget a step, i.e. adding the device driver to the PATH in the Docker container? (is that a thing?)

Is there some alternative way to do access the cDAQ from a Docker container?
