描述
Issue template
- 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
# ********************************************************
# * Anything else you want to do like clean up goes here *
# ********************************************************
# [Optional] Set the default user. Omit if you want to keep the default as root.
USER $USERNAME
CMD ["/bin/bash"]
devcontainer.json
{
"name": "ROS 2 Development Container",
"privileged": true,
"remoteUser": "Jakub",
"build": {
"dockerfile": "Dockerfile",
"args": {
"USERNAME": "Jakub"
}
},
"workspaceFolder": "/home/ws",
"workspaceMount": "source=${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.

- 送出 Pull Request,並在描述裡引用這個 Issue 編號。
研究方向
從 Dockerfile 和 devcontainer.json 開始,然後重現所連結的 first_application_linux 教學中的三終端設定。將 ROS_LOCALHOST_ONLY 和 ROS_DOMAIN_ID 設定與 agent 和 ping_pong 指令進行比較,並使用 ros2 topic list 驗證結果。當第三個終端中可以看到 /microROS/pong 時即表示完成。
