Nav2 is the Navigation stack for ROS2 (foxy). This post lists out the step required to setup and test Nav2 stack inside a Docker container.
Install Docker by going though the Docker Docs.
Pull the ROS2 docker image from hub.docker.com:
docker pull tsadarsh/ros2-foxy
To view the GUI applications like RViz and Gazebo, enable clients to access your device XServer:
xhost +
Set DISPLAY variable and mount X11 unix-domain socket to pipe the GUI applications outside the container:
docker run -it -e DISPLAY=$DISPLAY -v /tmp/.X11-unix/:/tmp/.X11-unix/ tsadarsh/ros2-foxy
Run a sudo apt update
Follow the Getting started guide from the official ROS2 docs and install:
sudo apt install ros-foxy-navigation2
sudo apt install ros-foxy-nav2-bringup
Install the Turtlebot 3 packages:
sudo apt install ros-foxy-turtlebot3*
To run the example, first source the foxy setup.bash
and set the environment variables:
source /opt/ros/<ros2-distro>/setup.bash
export TURTLEBOT3_MODEL=waffle
export GAZEBO_MODEL_PATH=$GAZEBO_MODEL_PATH:/opt/ros/<ros2-distro>/share/turtlebot3_gazebo/models
Finally launch the example turtlebot3 simulation:
ros2 launch nav2_bringup tb3_simulation_launch.py headless:=False
Note: Gazebo initially takes 5-10 minutes to start, download and cache all the required models. Until then the screen appears to be frozen.
If you encounter this error: libGL error: MESA-LOADER: failed to open amdgpu: /usr/lib/dri/amdgpu_dri.so: cannot open shared object file: No such file or directory (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri, suffix _dri)
, then mount /dev/dri
to your container:
docker run -it -e DISPLAY=$DISPLAY -v /tmp/.X11-unix/:/tmp/.X11-unix/ -v /dev/dri:/dev/dri tsadarsh/ros2-foxy
