ros_demo_module2

A demo module that includes a ROS 2 package to demonstrate inter-container communication in ROS 2.

Requirements

• Docker Engine
• Docker Compose plugin (If you're using Compose version 1, you need to use "docker-compose" instead of "docker compose" in your commands!)

Setup

1. Clone the repository

2. Go into the repository's Docker directory and run Docker Compose up

cd ros_demo_module1/docker \
&& sudo docker compose up

The Docker image gets built and after that, compose will start up a container that automatically builds the Colcon workspace and starts the launch file that was specified in docker/ros_entrypoint.sh which gets copied into the image during the build process.

You can stop the nodes at any time using CTRL + C in the command line. The compose will stop the container (it does not delete it!). This means you can start the container again using sudo docker compose up.

If you want to run the container detached, add the -d flag to the compose command like this:

sudo docker compose up -d

If you do this, you will have to sudo docker compose stop to stop the container or sudo docker compose down to completely remove it.
