Container Keyboard to Chromium Kiosk?

Product support balenaOS
1

Hey folks…

First post. We really love balenaOS and balenaCloud.

We are trying to deploy multiple PIs that launch chromium in kiosk mode. Everything is loading up and running and chromium loads the kiosk site correctly, but the local input devices are not seen by chromium for some reason. DMESG from within the container does show the touchscreen, keyboard, mouse and wedge scanner.

Am I missing something obvious??

Hey Jay,

One of my colleagues pointed me over to this article. Can you confirm the following?

  • Make sure your container is privileged in docker-compose.yml
  • Make sure you enable udevd
  • Which base container image are you using?

Cheers,
Trevor Sullivan

Thanks Trevor. See below. I am assuming udev is enabled as udevadm does seem to work … though issuing udev from the CLI returns:

bash: udev: command not found

docker-compose.yml

And here is the dockerfile…

ADD raspberry.png /etc/wallpaper.png

ENV UDEV=1

ADD run /bin/run

ENTRYPOINT [ “/bin/run” ]

Hey Jay,

Thanks for that additional detail. Are there any other files besides the run executable? Would you be willing to provide this whole project in a GitHub or GitLab repository, so I can try to reproduce it on one of my Raspberry Pi devices?

Cheers,
Trevor Sullivan

Hi Jacob,

I’d recommend opening up a new thread, linking back to this one for reference, and including the details around:

  • Hardware platform
  • What behavior you’re seeing (ie. observed

I’d also recommend checking out this example repository: GitHub - balena-io-experimental/balena-electronjs: electronJS-based resin application template

Cheers,
