Publish custom Hass.io addon with hassio-builder

Development
1

Hi Hass.io community,

I built a custom Hass.io addon which is ready for being published to DockerHub.

I followed the instructions from the developer documentation, but when I execute any command via the hassio-builder container it fails with a permission denied error:

$ docker run --rm --privileged homeassistant/amd64-builder --help
/usr/bin/bashio: line 26: /usr/bin/builder.sh: Permission denied

Note: I execute this command from my local development machine.

Has anyone of you published a custom addon via the hassio-builder ?
Am I missing something ?

Many thanks for your support in advance.
