How to run the Docker image to see the changes made on script?

Dockerfile is look like this:

FROM python:3

ADD my_script.py /

RUN pip install pystrich

CMD [ "python", "./my_script.py" ]

This runs smoothly, whatever the output is from my_script.py, docker run command gives that output.

Once I made changes on my_script.py, do I need to re-run the docker build command and run that image again to see the changes from output?

Yes. You need to rebuild the image because you add it to the image at build time.

You can avoid the re-build if you map the file as a volume when you run the container.

FROM python:3

RUN pip install pystrich

CMD [ "python", "/my_script.py" ]

docker run -v my_script.py:/my_script.py ...
