Warning when launching a node in a container

Execution environment
Ubuntu20.04.6 LTS
Docker version 26.1.3, build b72abbb
ros2 humble

When I run femto_bolt.launch.py in my own docker container, I get the following warning.

ros2 launch_femto_bolt.launch.py

[component_container-1] libEGL warning: egl: failed to create dri2 screen
[component_container-1] GlContext::Initialize eglInitialize error code = 0x3001
[component_container-1] libEGL warning: failed to open /dev/dri/renderD129: Permission denied

I think this is due to the fact that the proper graphics drivers are not installed in my container, but could you please tell me what specific libraries are required to be installed?

If you have any information necessary to investigate, please direct me.
I will try to provide as much information as possible.

Thank you in advance.

Make sure you have Installed udev rules on the host side. Additionally, you need to mount it in /dev/shm, and then mount the entire /dev directory into the Docker container.
