Connecting Realsense camera in LXC container

Setting Up RealSense in LXC

Introduction

This guide explains how to set up an additional RealSense camera in an LXC container running ubuntu 20.04 Focal. The container uses Ubuntu 22.04 for newer software compatibility.

Steps

1. Prepare the Container

1. Install LXC:

   sudo apt-get install lxc

2. Launch the Container:

   lxc launch ubuntu:22.04 my-container

3. Install Required Software in the Container:

   sudo apt-get install librealsense2 ros-foxy-desktop realsense2-camera

2. Device Mapping

1. Identify Device Information:

   lsusb

   Note the vendorid and productid.

2. Map the USB Device:

   lxc config device add my-container realsense usb vendorid=8086 productid=0b07 gid=1000

3. Video Devices Mapping

1. Map /dev/videoX Devices:

   ls -la /dev/video*
   lxc config device add my-container video0 unix-char path=/dev/video0 gid=1000
   lxc config device add my-container video1 unix-char path=/dev/video1 gid=1000

4. Restart and Test

1. Restart the Container:

   lxc restart my-container

2. Test the Setup:

   source /opt/ros/foxy/setup.bash
   ros2 launch realsense2_camera rs_launch.py

Conclusion

This setup allows the use of the RealSense D435i camera within an LXC container on a Jetson device, leveraging the host’s kernel and maintaining compatibility with other RealSense cameras.
