Challenges of using Containers to Run Graphical Embedded Systems
summary
Tests run on iMX6 (Etna/Mesa) and iMX8 (Vivante proprietary) using Fedora on the host and Ubuntu images in Docker, with x11docker and GLMark2 for benchmarks. Running X11 or Wayland clients inside containers requires sharing GPU devices (e.g. /dev/dri and sometimes /dev/galcore), building Weston 7.0 on iMX6 to fix a bug, and copying vendor libs into the image. Measured frame rates match host-native runs, so containerization does not hurt 3D performance, while Wayland over X11 improves security.
