Help on creating Addons

I went through the tutorial on making addons.
The examples works fine, but when I try to add a pre-made python code, I cannot get it to run

My Dockerfile looks like this:

FROM %%BASE_IMAGE%%
ENV LANG C.UTF-8
RUN apk add --no-cache python3
'# Copy data for add-on
COPY run.sh /
RUN chmod a+x /run.sh
CMD [ “/run.sh” ]

My config.json looks like this:

{
“name”: “Sector Alarm”,
“version”: “1.1.4”,
“slug”: “sector_alarm”,
“description”: “Testing Sector Alarm Integration”,
“startup”: “before”,
“boot”: “auto”,
“options”: {},
“schema”: {}
}

And my run.sh looks like this:

python3 sectoralarm

Where “sectoralarm” is the .py file to be run.

When installing/running the addon, I get the following error:

starting version 3.2.2
python3: can’t open file ‘sectoralarm’: [Errno 2] No such file or directory

In the Dockerfile you forgot to copy your sectoralarm file.

Refrasing the whole thing…
I want to make an add-on from this: https://github.com/petterl/python-sectoralarm
