Fullscreen webkit browser with HW accelerated CSS, WebGL, and HTML5 video on the RaspberryPi 3

Hello,
I’m also working on a digital signage project. I will need to run videos and HTML 5 animations there,
I’m trying to setup a docker compose with balena-wifi, wpe and a node express server to host the web app that will be running on wpe. I’m having trouble making it work… anyone has any example with that setup?

It’s basically this: https://www.balena.io/docs/learn/develop/multicontainer/ + WPE and Balena WIFI to help users connect their PI to the wifi, since I won’t know the wifi credential in advance.
