how can i set up rtabmap ros2 humble docker container with realsense d455

[sid leesa]

Hi, I’m trying to use RTAB-Map in a ROS 2 Humble Docker container with RealSense D455.

I cloned the RTAB-Map repository using the ros2 branch:
git clone --branch ros2 https://github.com/introlab/rtabmap_ros.git

I built it with colcon build in my workspace before entering the container.

After I entered the container, there is no RTAB-Map-related directory.
Because of this, I cannot run colcon build inside the container.
Why does this happen? Did I miss something in the Docker setup?

Thanks in advance!
