Steps for reproducing this issue:

1. Create Dockerfie

FROM python

RUN python -m venv penv
RUN . penv/bin/activate

RUN pip install --upgrade pip setuptools wheel swig
RUN pip install PyKCS11

2. build image

   docker build .

It looks like you have a problem with your installation of swig:

         File "/usr/local/bin/swig", line 5, in <module>
           from swig import swig

Install the swig Debian package, not the Pypi package.
