Hardware description: Windows 11, Docker inside VS Code with ROS2
OS: Linux
Installation type: Installed though first_application_linux
Version or commit hash: humble

Steps to reproduce the issue

I followed the tutorial with modified files to make in work on Windows 11. VS Code configuration: Dockerfile

FROM osrf/ros:humble-desktop
ARG USERNAME=Jakub
ARG USER_UID=1000
ARG USER_GID=$USER_UID

# Create the user
RUN groupadd --gid $USER_GID $USERNAME \
    && useradd --uid $USER_UID --gid $USER_GID -m $USERNAME \
    #
    # [Optional] Add sudo support. Omit if you don't need to install software after connecting.
    && apt-get update \
    && apt-get install -y sudo \
    && echo $USERNAME ALL=\(root\) NOPASSWD:ALL > /etc/sudoers.d/$USERNAME \
    && chmod 0440 /etc/sudoers.d/$USERNAME
RUN apt-get update && apt-get upgrade -y
RUN apt-get install -y python3-pip
ENV SHELL /bin/bash

# ********************************************************

{
    "name": "ROS 2 Development Container",
    "privileged": true,
    "remoteUser": "Jakub",
    "build": {
        "dockerfile": "Dockerfile",
        "args": {
            "USERNAME": "Jakub"
        }
    },
    "workspaceFolder": "/home/ws",
    "workspaceMount": "source=${localWorkspaceFolder},target=/home/ws/src,type=bind",
    "customizations": {
        "vscode": {
            "extensions":[
                "ms-vscode.cpptools",
                "ms-vscode.cpptools-themes",
                "twxs.cmake",
                "donjayamanne.python-extension-pack",
                "eamodio.gitlens",
                "ms-iot.vscode-ros"
            ]
        }
    },
    "containerEnv": {
        "ROS_LOCALHOST_ONLY": "1",
        "ROS_DOMAIN_ID": "42"
    },
    "remoteEnv": {
        "DISPLAY": "host.docker.internal:0"
      },
    "runArgs": [
        "-e", "DISPLAY=${env:DISPLAY}",
        "--gpus=all"
    ],
    "mounts": [
        "source=${localWorkspaceFolder}/../cache/ROS_DISTRO/build,target=/home/ws/build,type=bind",
        "source=${localWorkspaceFolder}/../cache/ROS_DISTRO/install,target=/home/ws/install,type=bind",
        "source=${localWorkspaceFolder}/../cache/ROS_DISTRO/log,target=/home/ws/log,type=bind"
    ],
    "postCreateCommand": "sudo rosdep update && sudo rosdep install --from-paths src --ignore-src -y && sudo chown -R Jakub /home/ws/"
}

Then inside the docker I followed the tutorial. I try to run: First terminal:

source /opt/ros/$ROS_DISTRO/setup.bash
source install/local_setup.bash
ros2 run micro_ros_agent micro_ros_agent udp4 --port 8888

Second terminal:

source /opt/ros/$ROS_DISTRO/setup.bash
source install/local_setup.bash

# Use RMW Micro XRCE-DDS implementation
export RMW_IMPLEMENTATION=rmw_microxrcedds

# Run a micro-ROS node
ros2 run micro_ros_demos_rclc ping_pong

Third terminal:

source /opt/ros/$ROS_DISTRO/setup.bash
source install/local_setup.bash
ros2 topic list

Expected behavior

In the third topic I should be able to see topic named /microROS/pong.

Actual behavior

There are only two topics:

/parameter_events
/rosout

Additional information

When I try to run rviz2 its working correctly, I am able to see topics in every terminal.

Could you share your micro-ROS Agent output using the flag -v6?

Nov 14 '23 14:11 pablogs9

Output from: ros2 run micro_ros_agent micro_ros_agent udp4 --port 8888 -v6 after runnig ros2 run micro_ros_demos_rclc ping_pong and waiting for 7 messages. Also during run I tried in another terminal to list topics.

Does it works if you do in ROS 2 terminal: ros2 daemon stop and the ROS_DOMAIN_ID=0 ros2 topic list ?

Nov 14 '23 14:11 pablogs9

No, unfortunately. I tried to write it in each terminal but that does not help.

Nov 14 '23 14:11 Jakubach

What does means "When I try to run rviz2 its working correctly, I am able to see topics in every terminal." ??

Nov 14 '23 15:11 pablogs9

When I start rviz2, then I can see topics in another terminals:

/clicked_point
/goal_pose
/initialpose
/parameter_events
/rosout
/tf
/tf_static

but when I would like to see topics from micro-ros example then it is impossible.

Nov 14 '23 15:11 Jakubach

The micro-ROS Agent is working properly since it is publishing and subscribing to DDS/ROS2 dataspace as you can see in the log ( <<DDS>> and >> DDS <<). You need to check if your docker configuration allows you to communicate via DDS with the instance where you are running the ROS 2 CLI.

Nov 14 '23 15:11 pablogs9

I just checked another example from eProsima and it works correctly in every terminal.

Launch a micro-ROS Agent with: ros2 run micro_ros_agent micro_ros_agent udp4 --port 8888 -v6
Launch a micro-ROS Client publisher application: ros2 run micro_ros_demos_rclc int32_publisher
Launch a micro-ROS Client subscriber application: ros2 run micro_ros_demos_rclc int32_subscriber

The problem is probably caused by this line during launching the not working example:

# Use RMW Micro XRCE-DDS implementation
export RMW_IMPLEMENTATION=rmw_microxrcedds

But without this line the example is not even starting properly so I am not able to run it. Also with this line the above example with int32_publisher is also not working (not showing topics).

Nov 14 '23 16:11 Jakubach

Same problem here, and I am not using docker.

Trying the pingpong node, and not getting any topics from uros.

Nov 24 '23 15:11 flabrosse

When I try the int32 publisher and subscriber examples, I can't see a topic when only the publisher is started. Once the subscriber is started, then I can see the /std_msgs_msg_Int32 topic, and info -v indicates that there are two subscribers to it, both int32_subscriber_rclc, and no publishers.

Nov 24 '23 15:11 flabrosse

Another piece of info: When I run the node int32_publisher only, ros2 node list shows no running node. If I then also run int32_subscriber then the node is listed as running, but only this one, still not the publisher.
