In your Dockerfile, either of these should work:

  • Use the ENV instruction (ENV PYTHONPATH="/:$PYTHONPATH")
  • Use a prefix during the RUN instruction (RUN export PYTHONPATH=/:$PYTHONPATH && <do something>)

The former will persist the changes across layers. The latter will take effect in that layer/RUN command
