[FIXED] How to run a ROS2 node inside docker image?

Issue

I have a ros2 package and successfully create a docker image of it. Then when im inside the container i would like to run only one single node of the ros2 package. So first create the environment with PATH=$PATH:/home/user/.local/bin then vcs import . <system_integration/ros.repos then docker pull ghcr.io/test-inc/base_images:foxy. Im running and executing the docker with

docker run --name test -d --rm -v $(pwd):/home/ros2/foxy/src ghcr.io/company-inc/robot1_vnc_ros2:foxy

docker exec -it test /bin/bash

Then when Im inside the docker I build the package with

colcon build --symlink-install --event-handlers console_cohesion+ --cmake-args -DCMAKE_BUILD_TYPE=Release --packages-up-to system_integration

So now im inside the docker in the root@1942eef8d977:~/ros2/foxy and would like to run one python node. But ros2 run package_name node_name would not work right? Im not familiar much with docker so not sure how to run the node. Any help

Thanks

Solution

Have you sourced the setup file within the container?

Where ever the package source is located, you need to run source ./install/setup.bash
