Building micro_ros_agent inside docker container

I’ve alredy read this thred but it doesn’t helpd me.

I’m using JetPack Version: 4.4.1-b50 (is there instructions to update to 4.6?) and dustynv/ros:humble-ros-base-l4t-r32.7.1 base image.
the part of my Dockerfile that faild is:

RUN git clone -b humble src/micro_ros_setup && \
    # sudo rosdep fix-permissions && \
    rosdep update && \
    rosdep install --from-paths src --ignore-src -y && \
    colcon build

I get:

ERROR: the following packages/stacks could not have their rosdep keys resolved to system dependencies:
micro_ros_setup: No definition of [ament_cmake] for OS version [bionic]



ros:humble-ros-base requrires L4T >=32.6 so please upgrade your environment into JetPack >= 4.6.


Hello, I’ve updated my system following this steps, the ones under “To update to a new minor release”
Now I have:

Welcome to Ubuntu 18.04.6 LTS (GNU/Linux 4.9.337-tegra aarch64)

elgarbe@jetson:~$ head -1 /etc/nv_tegra_release
# R32 (release), REVISION: 7.4, GCID: 33514132, BOARD: t210ref, EABI: aarch64, DATE:Fri Jun  9 04:25:08 UTC 2023
elgarbe@jetson:~$ sudo apt-cache show nvidia-jetpack
Package: nvidia-jetpack
Version: 4.6.4-b39

Is my system updated correctly?

Now, I use the following:

elgarbe@jetson:~$ docker run --privileged --runtime nvidia -it --rm --network=bridge dustynv/ros:humble-ros-base-l4t-r32.7.1
sourcing   /opt/ros/humble/install/setup.bash
ROS_ROOT   /opt/ros/humble
root@a3b2e6157c59:/# apt-mark hold '*opencv*' && apt-get update && apt dist-upgrade -y

I have to use bridge network in this case in order to have internet connection inside the container, I’m not sure why.
Then follow the steps to build micro_ros agent from here:

root@a3b2e6157c59:/# mkdir uros_ws && cd uros_ws

then continue with this steps:

I take this issue

but the problem continue after adding the flag to colcon build.

Any advice?


Ok, I’ve managed to make it work.
I left the files here for future references:


FROM dustynv/ros:humble-ros-base-l4t-r32.7.1

RUN mkdir -p /home/microros_ws
WORKDIR /home/microros_ws

RUN mkdir src \
    && git -C src clone -b $ROS_DISTRO \
    && git -C src clone -b $ROS_DISTRO  \
    && . /opt/ros/$ROS_DISTRO/install/ \
    &&  apt update \
    &&  apt install -y python3-pip \
    libspdlog-dev \
    libfmt-dev \
    &&  apt autoremove -y \
    &&  sudo rosdep fix-permissions \
    &&  rosdep update \
    &&  rosdep install --from-paths src --ignore-src -y \
    &&  colcon build --cmake-args -DUAGENT_BUILD_EXECUTABLE=OFF -DUAGENT_P2P_PROFILE=OFF -DUAGENT_USE_SYSTEM_LOGGER=ON --no-warn-unused-cli \
    &&  rm -rf log/ build/ src/* \
    &&  rm -rf /var/lib/apt/lists/*



CMD ["bash"]


version: '3.4'
    network_mode: "host"
    privileged: true
      context: .
      dockerfile: Dockerfile
      - /etc/timezone:/etc/timezone:ro
      - /etc/localtime:/etc/localtime:ro
    command: ros2 run micro_ros_agent micro_ros_agent serial -v --dev /dev/ttyACM0

set -e
source /opt/ros/humble/install/setup.bash
source /home/microros_ws/install/setup.bash
exec "$@"

Then run this command on jetson nano:

docker-compose up --build

and after building the image it will start micro-ros-agent.
The use of docker-compose will allow us to run other packages.

Thank and best regards

Good to know it works now.
Thanks for the feedback.
