No module named 'production_settings'

[flashfingaz]

Hi,

I'm trying to deploy this plugin inside a docker installation via the official instructions but it fails with 'No module named 'production_settings'. I'm not sure whats the root cause of this problem as I did not find any import directive for 'production_settings'.

So far this seems only to affect the cashpayment plugin (tried with pretix-pages, pretix-passbook - could build both of them without this problem)

Maybe I'm just missing something here...

Any help would be great. Thanks in advance!

my Dockerfile looks like this:

FROM pretix/standalone:stable
USER root
RUN pip3 install pretix-cashpayment
USER pretixuser
RUN cd /pretix/src && make production

build output as follows:

I am not really sure, what this might be caused by... I'll have a look at it and try to figure it out.

Also, paging @raphaelm, the almighty pretix-god, for further insights, as the only place I could find production_settings is in https://github.com/pretix/pretix/blob/master/deployment/docker/production_settings.py ;-)

[raphaelm]

My wild guess would be that you need to chdir before you pip install in your dockerfile:

FROM pretix/standalone:stable
USER root
RUN cd /pretix/src && pip3 install pretix-cashpayment
USER pretixuser
RUN cd /pretix/src && make production

Haven't tested it, though.

I tried as @raphaelm suggested to cd into /pretix/src via Dockerfile and also tried to add it to PATH but the situation remains. I will try around some more as it seems PATH is not modified permanently in the docker build env.

current Dockerfile:

FROM pretix/standalone:stable
USER root
RUN export PATH=$PATH:/pretix/src && pip3 install pretix-cashpayment
USER pretixuser
RUN cd /pretix/src && make production

[pc-coholic]

Please try this:

FROM pretix/standalone:stable
USER root
ENV DJANGO_SETTINGS_MODULE=
RUN pip3 install pretix-cashpayment
ENV DJANGO_SETTINGS_MODULE=production_settings
USER pretixuser
RUN cd /pretix/src && make production

[flashfingaz]

PYTHONPATH did the trick, the following Dockerfile actually worked for me to build the plugin:

FROM pretix/standalone:stable
USER root
RUN export PYTHONPATH=$PYTHONPATH:/pretix/src && pip3 install pretix-cashpayment
USER pretixuser
RUN cd /pretix/src && make production

[flashfingaz]

@pc-coholic just now saw your answer. tried it and it works as well.

Thx guys, your fast input made this horrible problem dissolve in a flash :) 👍

I ran into this issue. I think the root cause is lack of DJANGO_SETTINGS_MODULE. I specified it as in the docs and it worked.

RUN DJANGO_SETTINGS_MODULE=pretix.settings pip install whatever
