Alternate node name for component_container results in warning #346
Description
Bug report
I'm following the tutorial at https://index.ros.org/doc/ros2/Tutorials/Composition/#remapping-container-name-and-namespace . When I run the component_container with an alternate node name (by specifying __node:=MyContainer), I always get a warning when inserting components into the container.
Required Info:
- Operating System:
- Ubuntu 18.04
- Installation type:
- Source
- Version or commit hash:
- DDS implementation:
- Fast-RTPS
- Client library (if applicable):
- rclcpp_components
Steps to reproduce issue
In terminal 1:
ros2 run rclcpp_components component_container __node:=MyContainer
In terminal 2:
ros2 component load /MyContainer composition composition::Listener
Expected behavior
Composition Listener is loaded into the container without warnings.
Actual behavior
In the terminal running the component_container:
[INFO] [MyContainer]: Load Library: /home/ubuntu/ros2_ws/install/composition/lib/liblistener_component.so
[INFO] [MyContainer]: Found class: rclcpp_components::NodeFactoryTemplate<composition::Listener>
[INFO] [MyContainer]: Instantiate class: rclcpp_components::NodeFactoryTemplate<composition::Listener>
[WARN] [rcl.logging_rosout]: Publisher already registered for provided node name. If this is due to multiple nodes with the same name then all logs for that logger name will go out over the existing publisher. As soon as any node with that name is destructed it will unregister the publisher, preventing any further logs for that name from being published on the rosout topic.
Additional information
If I run the component_container without __node:=MyContainer, no error is shown. Also, using a namespace (__ns:=/ns) doesn't cause this to happen, only the change in node name.
