You can add a pip install ibm_db in your dockerfile or create a requirements.txt file. And call him in your dockerfile with :

 ADD        ./requirements.txt ./
 RUN        python3 -m pip install -r requirements.txt

EDIT It worked for me : In my dockerfile :

FROM       python:3.6
ADD        ./requirements.txt ./
RUN        python3 -m pip install -r requirements.txt
ADD        ./test.py /run

After building succesfully I ran my image with

docker run --name testpython testpython:1 sleep 3600

Go in my container

docker exec -it testpython /bin/bash

And when I run a python console or my test script, the import is OK.

NOTE : With the image python:3.6.8-alpine3.9 the build doesn't work. Check this to see why
