How to connect to SICK TIM LiDAR through docker?

asked 2020-12-14 08:01:41 -0500

Py gravatar image

I am able to connect to my SICK TIM LiDAR fine when running it from my machine. Here's the basic launch file:

<launch>

    <node name="sick_tim310_1" pkg="sick_tim" type="sick_tim310" respawn="false" output="screen">
    </node>

</launch>

However, when I try to containerise this with Docker it does not connect to the LiDAR via USB and I get the message:

process[sick_tim310_1-2]: started with pid [64]
/opt/ros/noetic/lib/sick_tim/sick_tim310: error while loading shared libraries: libdiagnostic_updater.so: cannot open shared object file: No such file or directory
[sick_tim310_1-2] process has died [pid 64, exit code 127, cmd /opt/ros/noetic/lib/sick_tim/sick_tim310 __name:=sick_tim310_1 __log:=/root/.ros/log/bc9ceac0-3e11-11eb-a6cb-50eb712545a4/sick_tim310_1-2.log].
log file: /root/.ros/log/bc9ceac0-3e11-11eb-a6cb-50eb712545a4/sick_tim310_1-2*.log

Here's the minimal Docker file:

FROM osrf/ros:noetic-desktop-full

RUN apt-get update && apt-get install -q -y nano && \

RUN bash -c "source /opt/ros/noetic/setup.bash && \
             cd ~ && \
             mkdir -p /catkin_ws/src && \
             cd /catkin_ws/src && \
             catkin_init_workspace && \
             mkdir my_package"

COPY . /catkin_ws/src/my_package
WORKDIR ~

RUN bash -c "source /opt/ros/noetic/setup.bash && \
             cd /catkin_ws/ && \
             catkin_make"

RUN bash -c "chmod +x /catkin_ws/src/my_package/container_entrypoint.sh"

RUN bash -c "source /opt/ros/noetic/setup.bash && \
                       source /catkin_ws/devel/setup.bash && \
                       cd && \
                       sudo rm /etc/ros/rosdep/sources.list.d/20-default.list && \
                       cd /catkin_ws && \
                       rosdep init && \
                       rosdep update && \
                       rosdep install --from-paths src --ignore-src --rosdistro=noetic -y"

ENTRYPOINT ["/catkin_ws/src/my_package/container_entrypoint.sh"]

CMD ["bash"]

The container_entrypoint.sh script referenced is:

#!/bin/bash

set -e

source /opt/ros/noetic/setup.bash
source /catkin_ws/devel/setup.bash

exec "$@"

The container is run with this script:

#!/bin/bash

docker run -it \
    --rm \
    --privileged \
    --net=host \
    my_package:latest \
    /bin/bash -c \
    "
     roslaunch my_package my_package.launch
    "
export containerId=$(docker ps -l -q)

Could anyone point out what I might be doing wrong please?

Is this library installed?

As suggested in the first comment, diagnostic_updater was missing so installing this fixed the problem.
