This action could be used as a continuous integration (CI) to build and test a ROS 2 project.

This action works by building and testing a ROS 2 project inside a Docker's container using the official ROS 2 Docker image. To handle which ROS 2 environment to be used, this action uses a Docker in Docker (DinD). Hence the CI process happens inside the container's container, not just the first layer of the Docker's container for GitHub Actions. Although, The CI process is guaranteed to be fast (approximately 3-5 minutes, depends on each package) as almost every component of the ROS 2 has already been installed inside the Docker's image.

To be able to build and test the project inside the repository, This action requires the Checkout action. Before the build process, the project files will be put under the /ws/repo directory inside the container. Then, the build and test process will be done using colcon inside the /ws directory. After the test process happens, the build results (build, install, and log) will be copied inside the /ws/repo/.ws.

The drawback of using this action is it still needs to install external dependencies that haven't been included in the ROS 2 default installation. But that problem could be solved by adding a apt-packages or a pip-packages input inside the action configuration (see this) or by cloning external packages inside the /ws directory before the build process happens (see this).

For more information, see the action.yml and the GitHub Actions guide.
