Help develop addon

Development
1

Hi.
I’m trying to develop an addon starting from my python script. It requires just python and paho-mqtt.
The script works fine on my linux machine, since a week, so i started to move the script into an addon for let it run directly on hass.
I follow the template and make a Dockerfile, run.sh etc.
The installation fail with this error:

1/13 : ARG BUILD_FROM

So the problem, if i inderstood, is from the Dockerfile:

> ARG BUILD_FROM
> FROM $BUILD_FROM
> 
> ENV LANG C.UTF-8
> 
> SHELL ["/bin/bash", "-o", "pipefail", "-c"]
>

> RUN \
>     apk add --no-cache \
>          python3 \
>              py3-pip \
>      \
>      && pip3 install paho-mqtt \
> 
> # Copy data for add-on
> COPY run.sh /
> COPY pws_server.py /
> RUN chmod a+x /run.sh
> 
> CMD [ "/run.sh" ]

Someone can help me?

Copy rootfs is what you want. It will copy the rootfs files from your repo.

Mine is down below… Although mine isn’t necessarily great…

Hi @HasQT thanks for your support. I tried adding COPY root / and also to add and remove mine COPY commands, same error:

>     RUN     apk add --no-cache 	 python3              py3-pip           && pip3 install paho-mqtt COPY rootfs /

I guess it would probably help if you shared more of your addon. Is there a repo somewhere? Or at the very least what’s in your build.yaml so its clear how $BUILD_FROM is being set.

Also if you aren’t using it there’s an alpine addon base image that comes with python and pip already installed here. If you use that as your base all you have to do is install paho-mqtt via pip.

&& pip3 install paho-mqtt \

should be

&& pip3 install paho-mqtt

you don’t need the \ as it is the last command

Yep, this let the addon to install. Thanks, now i try to make it works and make the configuration interactive.
