Problems getting this to work in Docker XBlock-SDK (without devstack)

[taniwallach]

I am trying to get this to work using an updated Docker version of the XBlock-SDK from https://github.com/taniwallach/xblock-sdk/tree/update-base-add-docker-compose-yml as a Docker image build using that branch does start up.

I ran into several problems, and still have not been able to get it to work.

My modified Dockerfile to overcome some of the issues I encountered is:

FROM xblock-sdk
RUN mkdir -p /usr/local/src/staff_graded-xblock
VOLUME ["/usr/local/src/staff_graded-xblock"]
RUN apt-get update && apt-get install -y gettext

# Upgrade pip
RUN echo "pip install -U pip" >> /usr/local/src/xblock-sdk/install_and_run_xblock.sh

# Next line fails, no such file
#RUN echo "pip install -r /usr/local/src/staff_graded-xblock/requirements.txt" >> /usr/local/src/xblock-sdk/install_and_run_xblock.sh
#
# so try this one instead - which does seem to work
RUN echo "pip install -r /usr/local/src/staff_graded-xblock/requirements/dev.txt" >> /usr/local/src/xblock-sdk/install_and_run_xblock.sh

RUN echo "pip install -e /usr/local/src/staff_graded-xblock" >> /usr/local/src/xblock-sdk/install_and_run_xblock.sh

# Need to add this to create database
RUN echo "python /usr/local/src/xblock-sdk/manage.py migrate" >> /usr/local/src/xblock-sdk/install_and_run_xblock.sh

# Skip translations - it fails
#RUN echo "cd /usr/local/src/staff_graded-xblock && make compile_translations && cd /usr/local/src/xblock-sdk" >> /usr/local/src/xblock-sdk/install_and_run_xblock.sh

RUN echo "exec python /usr/local/src/xblock-sdk/manage.py \"\$@\"" >> /usr/local/src/xblock-sdk/install_and_run_xblock.sh
RUN chmod +x /usr/local/src/xblock-sdk/install_and_run_xblock.sh
ENTRYPOINT ["/bin/bash", "/usr/local/src/xblock-sdk/install_and_run_xblock.sh"]
CMD ["runserver", "0.0.0.0:8000"]

which depends on the locally prepared xblock-sdk image.

1. Due to a failure to get the i8n code to work - the line to run it was commented out.
2. Add python /usr/local/src/xblock-sdk/manage.py migrate which is required to get the database initialized.

• This probably only needs to be done once and not on each restart.

The server does come up, but gives an error No module named 'lms' shown below from bulk_grades/api.py: The line triggering the error seems to be

from lms.djangoapps.grades import api as grades_api
