tomlankhorst / talker_listener_ros.launch

Last active June 3, 2020 10:08

Launch ROS nodes in a docker container (roscpp_tutorial/talker_listener). This example uses host networking, but creating a network and setting the ROS_MASTER_URI should work just as well. See: https://github.com/ros/ros_tutorials/tree/melodic-devel/roscpp_tutorials https://hub.docker.com/_/ros/

	<launch>
	<node launch-prefix="docker run --rm --name listener -v$HOME:$HOME -u$UID --privileged --net=host -eROS_HOME=$ROS_HOME ros:melodic-ros-base-bionic" name="listener" pkg="roscpp_tutorials" type="listener" output="screen"/>
	<node launch-prefix="docker run --rm --name talker -v$HOME:$HOME -u$UID --privileged --net=host -eROS_HOME=$ROS_HOME ros:melodic-ros-base-bionic" name="talker" pkg="roscpp_tutorials" type="talker" output="screen"/>
