I2c-tools - Add-on problem

Installation Home Assistant OS
1

I’m trying to make my first add-on. I think is useful to have quick i2c scan. So I’ve checked the repository and found package:
https://pkgs.alpinelinux.org/packages?name=i2c-tools&branch=edge
Then I’ve made Dockerfile:

ARG BUILD_FROM
FROM $BUILD_FROM
ENV LANG C.UTF-8

RUN apk add --no-cache musl i2c-tools

COPY run.sh /
RUN chmod a+x /run.sh
CMD [ "/run.sh" ]

Unfortunately, it doesn’t install. There’s error:
ERROR (SyncWorker_0) [hassio.docker.addon] Can't build local/armhf-addon-i2c_addon:1: The command '/bin/sh -c apk add --no-cache musl i2c-tools' returned a non-zero code: 1
When I left only musl without i2c-tools then it installs without problems.
Where can I check what exactly goes wrong?

I2C-tools isn’t available in the stable repository. To install, you must add the following repository, to your “/etc/apk/repositories”:
http://dl-cdn.alpinelinux.org/alpine/edge/testing

At the time of this post, it can be installed by current repository. But I could not manage to make it work. running “sudo i2cdetect -y 1” gives permission denied with docker.

I already added below to config.json:

"devices": ["/dev/i2c-1:/dev/i2c-1:rwm"],
"auto_uart": "yes",
 "full_access": "yes",
 "gpio": "yes"

Did you manage to get it working in the end?
